How to cut a pipe evenly with a grinder

How to saw off a profile pipe smoothly with a grinder

Quite often, when performing various construction or repair work, it becomes necessary to cut a pipe. This could be plumbing work, laying pipelines or installing heating systems, but in any case it is necessary to know how to cut a pipe evenly. Some features of performing this task will be discussed further.

45 degree cutting

One particular example of such a situation is the need to cut a metal pipe at an angle of 45 degrees. Such cutting of material is often required when laying water pipes or heating systems. In this case, you have to deal with steel pipes.

For these purposes, conventional cylindrical pipes are usually used. If we are talking about the installation of some kind of metal structures, then profile pipes of rectangular or square cross-section are more often used.

The main problem here is that in order for the elements to be connected to coincide, the cut must be as smooth as possible, which means that especially close attention should be paid to marking the material.

In cases where cutting at an angle is required, a simple square sheet of paper can be used as a marking template. It must be folded strictly diagonally, and then wrapped around the pipe with the template.

In this case, it is necessary to carefully ensure that the side of the sheet, which is located closer to the end of the pipe, is perpendicular to its central axis.

Next, using marking material, a series of dotted lines is applied and after the marking is completed along the entire circumference, the template can be removed.

If you have to cut a profile pipe, then it is advisable to make a special template from the same pipe, but with a larger cross-section. In this case, you will only have to use the measuring devices once.

To apply markings you will need to use a protractor or a construction square. After sawing off the template, the pipes to be cut can simply be inserted into it and marked.

This approach will significantly save work time and cutting a profile pipe at 45 degrees will be convenient.

As for what to use when carrying out work, you should choose the most suitable and familiar one. This can be a simple hacksaw for metal, or a grinder with an installed cutting disc.

90 degree cutting

When the need arises to cut at 90 degrees, the situation is even simpler. In the case of cylindrical elements, you can use the same sheet of paper that is used to wrap the pipe as a template. It is important to ensure that the edge of the sheet is smooth and matches the entire circumference. After marking is applied, the element to be cut is fixed and the cut is made.

How to cut a profile pipe lengthwise or crosswise: marking and cutting methods

In households, profile pipes are widely used in the manufacture of greenhouses, greenhouses, canopies to protect vehicles from precipitation and other structures. When working with this material, it is useful to know how to cut a profile pipe along a line or crosswise with the most accurate angle.

Among the large number of construction metal cutting tools, the leader in speed, ease of cutting and efficiency is the angle grinder (grinder), which is often present in the tool kit of any home craftsman. To cut a profile steel pipe using a grinder, you will need a regular metal disc and strict adherence to safety rules - breaking the disc into segments at high rotation speeds can lead to serious injuries.

Fig.1 Profile pipes in the household

How to cut a profile pipe straight across

Most often in households, a rectangular or square pipe metal profile with a wall thickness of no more than 3 mm is used, and cutting into separate sections is necessary when carrying out work on assembling welded frames.

To cut a pipe correctly, additional devices are used to mark and mark the cutting line; some of the devices serve as a support edge for the cutting disk.

The nuances of working with a rectangular section

Rectangular workpieces are much easier to cut lengthwise and crosswise at any angles than cylindrical elements, which are difficult to hold stationary on a flat surface.

Transverse cutting of workpieces at any angle does not present any particular difficulties - the line of the required angular slope is drawn on the side edge and always coincides with the calculated one (round elements require the use of special patterns, calculated on a computer, to align their edges at an angle other than a straight line).

The thickness of the walls of a metal profile when used in households rarely exceeds 5 mm - it is easy to cut using an angle grinder with any metal disc.

Rice. 2 Types of transverse marking methods

What tool is used

As noted above, the main tool for cutting metal parts at home is an angle grinder; if you don’t have one, you can use a hand-held hacksaw or a jigsaw, which can also cut metal materials with a special diamond-coated blade.

For cutting with a grinder, cut-off electrocorundum discs are used, which are not intended for grinding operations. As an auxiliary tool, a tape measure, a metal ruler, various types of clamps, pencils and markers for marking will be useful.

Paper pattern for pipe

Using a paper sheet is a simple method of marking a rectangular or square profile for precise cutting at an angle of 90 or 45 degrees towards its axis.

To make markings for cross cutting at an angle of 90 degrees, take a sheet of paper and wrap it around the pipe until the edges line up exactly, after which they are glued together. With this method, the cutting line is very clearly visible, unlike drawing it with a pencil or marker along the edge of the template.

After this, the profile is cut along the template edge alternately from all sides, trying to avoid complete cutting of the finishing sections - this can lead to the disk hitting sharp corners and its destruction.

A sheet of paper can also be used to mark the side walls of rectangular or square pipes. To do this, the paper sheet is folded diagonally, and the resulting 45-degree angle is applied to the side walls and the appropriate markings are made. To ensure that the side lines are at the same level, an acute angle is applied to the transverse line placed at an angle of 90 degrees to the axis, which is previously applied in the above manner.

Rice. 3 Using a steel template

Miter box for cutting pipes

It is very convenient to cut a profile pipe using a special template, which is an analogue of a construction miter box for cutting building materials at different angles.

To do this, using the above or another method, a metal template is made from a piece of profile pipe cut along the length; it can be designed to obtain a right angle or an angle of 45 degrees.

To cut a metal profile, apply a template to it and draw a line with a scriber, along which a cut is then made. In other cases, the template is held and a grinder is used to draw a line along the surface of the workpiece, trying to avoid strong pressing of the side surface of the disk against the attached metal template. Then the template is removed and cutting continues along a clearly visible depression on the edges of the workpiece.

Using a template, you can get a very straight cut line if you do not hold it manually, but secure it to the workpiece using clamps or mounting bolts.

To make your own fasteners, drill a hole in the side surface of the U-shaped plate of the template and weld a union nut at this point from the outside into which the bolt is screwed.

To secure the template, place it on the part to be cut and screw in the bolt, pressing the template surface against the workpiece, then use a grinder with a metal disc to make a cut, lightly touching the guide edge.

Rice. 4 How to cut a workpiece with a homemade machine

Other options

A good option for making a template is to use a short piece of larger diameter pipe for marking, the guide edge of which has been pre-cut at the desired angles. When marking, the part is placed on the pipe to be cut, after which its surface is marked with a marker or scriber. The second method is to rigidly fix the template on the workpiece using wedges or clamps, followed by cutting with a metal disc with light pressure on the side surface of the template part.

In order not to cut metal pipes or sheets of iron by eye, some home craftsmen use homemade fastening devices for the grinder, rigidly securing it to a vertically mounted spindle. When moving the tool from top to bottom, a stable, even cut occurs on the part located under the disk; if metal guides are fastened to the machine bed, then when a workpiece is applied to them, any desired cutting angle can be obtained.

Fig.5 Working with thick-walled steel

Cutting large diameter profile pipe

A large-diameter metal profile has thick walls and a lot of weight; if for cutting thin-walled parts (wall thickness up to 2 mm) it was possible to use thin disks of about 1 mm in size, then for cutting thick-walled metal they take 2 mm.

disc circles.

Accordingly, it is more convenient to cut thick walls with a large-diameter disk using a powerful large-sized construction angle grinder - household devices do not have enough power to quickly carry out work, and their small disks quickly wear down.

How to cut a pipe evenly with a grinder?

When working with construction or plumbing problems, you need to know how to cut a pipe evenly with a grinder . In the article we will look at quick and easy methods of how to properly cut a pipe with a grinder so that the result comes out flawless.

Cutting pipe at an angle of 45 and 90 degrees

If it is necessary to cut the pipe at an angle of 45 degrees, which is often required when laying water and heating pipes. Iron and cast iron pipes that have a cylindrical shape are often used. For installation work, rectangular or profile pipes are used. But you should cut the pipe correctly with a grinder so that you can connect it later without any problems. Therefore, you should carefully mark the pipe.

Some craftsmen try to mark the cutting area using a tape measure, but we warn you that the result, in my opinion, will not be good. For a good result, consider the following recommendations from experts.

Take a sheet of paper or cardboard, preferably A4, fold it at an angle and wrap it around the pipe where you plan to make an even cut. The edges of the paper must be completely aligned. And the side of the paper that was closer to the end of the pipe was perpendicular to the axis. Then mark a cutting line in a circle.

If you need to cut at an angle of 90 degrees, then solve the problem quickly using paper or masking tape. Wrap it around the pipe so that the ends match. Make even markings and saw off.

How to cut a profile pipe evenly?

Craftsmen recommend using a square when cutting a profile pipe. For this purpose, apply the square to the sides one by one, and turn and apply marks with smooth movements. After the steps, secure the pipe and cut. Prepare a template for yourself that will be needed later and will save time. It is better to create the action with a grinder, so the cut will be smoother.

How to cut a cast iron pipe?

When working with a metal pipe, keep in mind that it is a fragile material. Therefore, we will develop a method that would allow us to cut such metal without damage.

Before work, make notes for the cut, just like when working with iron pipes. Place a wooden beam for support. Walk the grinder around the circumference of the pipe, making small cuts. Later, take the chisels, stick them into the groove and hit them hard with a hammer. Keep in mind that for cutting metal pipes, cutting discs on a bakelite base are used.

How to cut a pipe with a grinder ! Preparation for welding!

Here you will clearly see how simple and easy it is to prepare a perfect pipe for welding!!!

If you don’t have a grinder at home to cut a cast iron sewer pipe or other purposes, use a hacksaw, chisels or special pipe cutters.

How to cut a gas pipe?

Cutting a gas pipe is a dangerous action, so it is best to leave it to the experts. If you are convinced that he is capable, then to cut metal, take a grinder, welding, hacksaw, or gas welding.

• Before the start of the working day, turn off the gas supply riser. Then release the rest of the gas from the pipe. For this purpose, light the gas in the burners and wait for it to go out.
• After these steps, cut. Using the welding method, the iron base burns when exposed to extreme temperatures. The result is quick and effective. If cutting or rooting gas pipes again requires experience.

Methods for cutting huge diameter pipes

There are a number of reliable tools for cutting huge diameter pipes, such as sewer pipes. Next, let's take a closer look at some of them:

• The grinder is a cheap and affordable option, but it is not considered the most dangerous when working with such materials. If you dare to use this method, be careful and use protective equipment.
• A roller machine (pipe cutter) is a tool adapted for similar manipulations. The device is attached and material removal begins. The clamping force is adjusted using mechanical devices. It is important to note that machine models differ in shape, so before implementation, take into account the size ratio with the pipe.
• Gas cutting is a more popular option for cutting larger diameter pipes and sheet metal. The cut occurs due to the action of a flame of the highest intensity, the metal melts and leaves the cut zone with a gas flow. This method is successful and effective.

How to cut a pipe lengthwise correctly?

A quick method to cut a pipe lengthwise using a grinder:

• Pay main attention to the markings.
• For this option, use the painting thread that was found when marking the walls.
• Before starting work, secure the pipe and, using small movements, painstakingly saw the pipe.
• It’s better not to rush, but delicately and slowly process the pipe parts, so the cutting disc will not jump off the marking lines. Remember safety precautions.

How to cut thin-walled pipes?

Thin-walled pipes are made of non-ferrous metals: aluminum, copper. Such work should be created delicately, because there is a high possibility of deformation of the material. For cutting, fillers are used, for example, sand. There is an option to carry out the work using a grinder or a special machine.

To summarize, we emphasize that cutting iron pipes is not an easy process, but anyone can do it better if they want. Using expert advice, you can easily cope with cutting pipes of various sizes and materials.

Also, do not forget to process the edges of the pipes after the cut with ratfil or sandpaper. And most importantly, you must keep this fact in mind when starting such actions; this is safety precautions. When starting work, wear a special suit (casing), a mask or closed-type glasses.

Your hands are also strongly protected from sparks, so use thick gloves.

How to cut a pipe evenly with a grinder

Cutting pipes is a fairly simple operation, but correct cutting of pipes, when the cut is located exactly at right angles to the surface of the product, is a responsible procedure.

However, I am not talking about cutting large diameter pipes. Indeed, in this case, to ensure proper welding or gluing, it is necessary to maintain an angle of 90 degrees.

For individual use

This category of tools is used in private and small commercial construction for the installation of pipeline systems (plumbing, heating, sewerage, ventilation) of small diameter.

Personally, in my practice I used the following devices:

Pruning cutters. Used for cutting polymer pipes with a diameter of up to 75 mm.

To provide the necessary force, the devices are equipped with a gear mechanism. Before cutting a metal-plastic pipe (or a polypropylene product), it must be placed on a special shelf. The design feature of the pruning shears will not allow the part to be installed crookedly, so the cut will always be made at a right angle to the surface.

Disc pipe cutter. A device for cutting pipes, in which the cutting part is made in the form of a disk made of very durable material with sharpened edges. It is pressed against the pipe wall with a lever and pulled around the entire circumference.

I use a disc pipe cutter to cut PVC pipes from which internal and external sewerage is constructed. It cannot be used for metal-plastic, since the applied force will cause the thin-walled material to crumple.

Guillotine. You can imagine the design features and operating principle of this cutting device if you have seen the execution instrument used in medieval France.

There is a knife on top, which is lowered along guides onto the pipe located below. Most often I used such a device for cutting a large number of pipes and the unit was equipped with an electric drive. However, models with a screw are available for sale.

Hacksaw for metal. Suitable for cutting pipes from any materials into required lengths. My grandfather taught me to use it. The special secret here is to apply strictly measured force, otherwise the canvas will break.

After making a cut with a hacksaw, burrs form at the end of the pipe. You need to get rid of them using a shaver or file. Otherwise, the pipe connection may not be airtight.

Angle grinder. We are talking, if anyone doesn’t know, about an ordinary grinder. A special cutting disc is placed on it, after which you can cut pipes of both small and large diameters.

As with a hacksaw, a grinder can work with any material: from plastic to metal and cast iron.

Jigsaw. This tool can also cut pipes, but even I, a person with considerable experience, was not always able to make a cut at a right angle.

Cutting technology

I’ll say right away that if you are going to make a plumbing or heating system from polypropylene or metal-plastic, it is better to immediately buy pruning shears. It's inexpensive, but makes the job a lot easier.

In all other cases, you can use improvised means.

Right angle

To cut a pipe at a 90 degree angle, I suggest marking it before cutting. To do this, you will not need a marker or pencil, as you might think, but a piece of paper or masking tape. I prefer the latter option as it sticks to the surface.

So, I’ll tell you the operation scheme:

• I measure the required length of pipe and place a small mark in the right place with a pencil or black marker.

First you need to mark the cut location.

• Then, focusing on the mark, I stick the tape. It is important to do everything so that the edges of the paper tape meet with maximum accuracy. If it works, then you can be sure that the cut will be made correctly.

Instead of tape, you can use Pipe Wrap tape.

• I then secure the pipe so it doesn't move while cutting. It is best to clamp the part in a vice or press it against a flat surface with something.

Before cutting, the pipe must be carefully secured.

To avoid pinching the cutting disc during the operation, the second end of the pipe must be left suspended, and the cut must be started from the top of the pipe.

• After this, all that remains is to make the cut using a grinder. You must make sure that the cutting disc runs exactly along the edge of the masking tape that you pasted earlier.

If the pipe has a large diameter, you need to cut the wall itself in separate sectors, gradually turning the pipe to the desired side.

Large diameter pipes are cut into sectors.

You need to deal a little differently with a cast iron pipe, which can split if cut incorrectly. In this case, I personally proceed like this:

• I cut the product along the entire diameter;
• then I take a chisel and tap the cut;
• from such an impact the product should burst along the depression made by the disk.

Oblique cut

Now I’ll tell you how to cut a pipe at 45 degrees. In this case, you can also use markup.

The scheme is like this:

• I take a square sheet of paper (the side of the square should be equal to the outer diameter of the pipe);
• I fold it diagonally;
• I wrap it around the pipe and secure it.

Marking the cutting line using a sheet of paper folded diagonally.

In this case, if you make a cut along the oblique edge of a paper sheet, the end will have an angle of 45 degrees.

But it is best not to philosophize, but to use an ordinary miter box, which is intended precisely for such cases. Structurally, the device I mentioned has the shape of an inverted letter P, the opposite slats of which have cuts at the desired angle.

Homemade universal pipe cutter from a grinder

To cut round pipes of different diameters, the master suggests making and using in the future a homemade universal pipe cutter from a grinder.

Of course, it will be easier for someone to cut the pipe evenly without this device. But for beginners who do not yet know how to properly handle an angle grinder, this homemade product may come in handy.

To make a universal pipe cutter, the author uses a 50*50 mm angle, four 201 bearings, four 6000 bearings, a piece of M12 pin and a piece of M10 pin.

Also, in the process of making a homemade product, some other materials may be required.

Main stages of work

First of all, from a construction corner 50x50 mm, you need to cut a workpiece 300 mm long.

Next, along the edges of the corner, the author cuts out “windows” so that the bearings can be installed later.

From the M12 stud it will be necessary to cut two blanks 28 cm long. The author puts bearings on them. Then the studs need to be welded to the corner.

The author cuts a piece of the required length from a 50x30 mm profile pipe and also welds it to the corner. A piece of sheet metal 4 mm thick is used as the base.

A corner will be attached to the metal plate, as well as a pendulum for the angle grinder based on housing bearings.

You will also need to make a mount for the grinder. To do this, you can use available materials.

Using a 25*25 mm profile pipe, the author connects the angle grinder mount to the pendulum.

The final part of the work

At the last stage, it remains to cut off another piece of the corner, which will fix the pipe during the cutting process.

You will also need to cut out “windows” in the workpiece in order to install 6000 bearings in them.

Then the master makes a simple clamp from sections of the profile pipe, which will press the corner to the workpiece.

After welding, we clean all the seams, and the homemade product is ready for use.

In everyday life, we are constantly faced with the need to lay pipelines from various materials, be it water supply, sewerage, heating, installation of cable ducts, or even the construction of frame structures in a house or country house.

This article will tell you how to evenly cut a pipe for certain purposes, if you do all the work yourself, that is, it provides detailed instructions for all technological operations.

In addition, let's talk about the variety of tools for amateur or industrial use.

What tools are used to cut pipes?

At first glance, it may seem that cutting pipes is a fairly simple process that is not worth special mention. However, this is not quite true.

It’s one thing when you don’t need precise, even cuts at an angle of 90º or any other, since no further welding or joining of the ends will be performed. And it’s a completely different matter when you need to make an absolutely precise cut.

Note that if it is necessary to cut oblique ends with an exact angle, it is worth consulting with experienced craftsmen.

Separately, it is worth mentioning pipes with a large diameter, when joining which a cut of exactly 90º must be ensured. Be that as it may, all these operations are performed using special equipment.

Tools for home and semi-professional use

To install water supply or sewerage systems, heating and ventilation circuits in home construction or when providing construction services, tools from this category are often used.

Among the most common devices are:

1. Cutters with pruner design . This tool is used for cutting polymer pipes whose cross-section does not exceed 75 mm. The gear mechanism of the device allows you to apply the force necessary for work. The design of such a cutter includes a special shelf on which the pipe is laid, which ensures an even cut at exactly 90º. Prices for such tools can be very different, it all depends on their quality, dimensions, capabilities, manufacturer and other factors.
2. Disc type pipe cutter

How to cut a profile pipe lengthwise - cutting technology

If cross-cutting a profile does not cause any particular difficulties, then a longitudinal cut, which is necessary for some work in the household, is more complex due to its length.

One of the problems when carrying it out is the accuracy of the markings; to apply it in the center or at another point of the cut edge, marks are placed along the entire length at the same distance from the side wall and then they are connected with a pencil, marker or scriber, using an even corner, construction paper, as a guide. usually a level, a profile from drywall.

Rice. 6 Cutting a pipe lengthwise along a guide angle

In order to cut a metal profile in the longitudinal direction, they drive the angle grinder along the line, gradually cutting a through hole - the method is not very accurate, the tool has to be held suspended without support.

A more convenient way to qualitatively cut a workpiece longitudinally is to use auxiliary supports in the form of a metal corner or even straight plates. To do this, the corner is attached to the surface of the workpiece using clamps and the grinder is guided along its side edge; if the length of the template corner is small, it is unscrewed and moved further to a new place, after which cutting is resumed.

How to cut a pipe straight - common options

Precise pipe cutting looks simple at first glance. This task is quite problematic, especially if you need to make a cut at a certain angle or a cut of a complex configuration. You can do this either with your own hands or with the help of a specialized tool.

Much here depends on the diameter of the product, the wall thickness, the material from which the pipe is made and, of course, the tool itself.

Photo of a hand pruner.

What tools are there?

Pipe cutting tools, like most existing tools, come in manual and electric versions. Both of these niches, in turn, contain specialized professional and applied amateur tools (find out here how to cut threads on a pipe at home).

For example, the question of how to cut a metal-plastic pipe can be solved in two ways.

On the one hand, there is a professional pruner, but on the other hand, you can use a regular hacksaw.

Roller pipe cutter.

• If we talk about pipes made of various types of plastic, then for material with a cross-section of up to 75 mm, a lot of special scissors are produced; professionals call them pruning cutters . Since plastic material is quite dense, all pruners are equipped with a gear mechanism that serves to increase the compression force. The price for such scissors starts from $10 and, depending on the quality, can reach up to $150.
• The next professional in cutting plastic is the disc pipe cutter . If the pruner works on the principle of ordinary scissors, then the cut is made using a sharp, heavy-duty disc. He presses himself against the wall and, rolling around it, makes an incision.

A pipe cutter is indispensable for thin-walled products, since cutting a metal-plastic pipe with a thin wall with pruning shears is difficult because it wrinkles.

Knife for roller cutter.

• The question of how to evenly cut a large-diameter pipe is easily solved by professionals; for this purpose, there is a guillotine adapted for cutting round products . Its operating principle is classic, with a knife on top and a semicircular bed on the bottom.

The device can be electrically driven and cut using hydraulics. There is also a guillotine with a manual, screw drive.

• In addition, there are a lot of specialized machines . Thus, lathes are used for perpendicular cuts. If the question arises of how to cut a pipe at 45 degrees or at any other angle, then, as a rule, band saws are needed.

Manual cutting process.

Important: the main difference between a professional tool and an amateur one is that the cut is performed with extreme precision. Plus, the edge does not require additional processing after finishing the work.

• But the necessary device is not always at hand, and buying it separately is expensive and does not always make sense . The leader among amateur tools is considered to be an ordinary hacksaw. It can easily cope with both metal and plastic, the main thing is to mark it correctly, but more on that later.
• Every good owner always has an angle grinder . With its help, having a certain skill, you can quite accurately unravel pipes of small and medium diameter. The big advantage of the grinder is that it can be used to work on any material, from polyethylene to cast iron or steel.
• At the end of our rating is a jigsaw. It is undoubtedly possible to work with it, but it is difficult to make precise cuts, plus the edges of the pipe will need to be further refined.

Power tools for large diameter pipes.

Using a tool such as a pruning shear or a disc pipe cutter does not require special training; it is easy to work with them efficiently. It's a completely different matter when you have to use improvised means.

Working with a hacksaw.

Making a perpendicular cut

There are several opinions on the topic of how to cut a pipe at 90 degrees. As in any business, a lot depends on the correctness of the markings. The most reliable folk method is to use a paper sheet or masking tape.

It is easier to work with tape; you need to carefully, without creases or distortions, stick it around the perimeter of the pipe. If both sides of the strip meet clearly, without shifts, then you already have 90º.

The product must be securely fastened before cutting, otherwise the pipe will rotate and you will not be able to unravel it smoothly. Ideally, of course, it is better to clamp it in a vice, but at the dacha you don’t always have such luxury. A small diameter pipe can be tied to a stool or table.

Working as a grinder.

To a large-diameter product, you need to attach 2 wooden support bars in parallel, which will prevent the pipe from rotating. It is most convenient to fasten with tape; a few turns made on both sides of the cut will securely fix the product.

Advice: before cutting the pipe evenly with a grinder, in some cases it is better to fasten it only on one side, leaving the other hanging. You need to cut from top to bottom to avoid pinching the disc.

Guillotine for pipes.

Returning to how to cut a large-diameter pipe, it should be noted that with a hacksaw or grinder, such a product should be cut into sectors, gradually.

In the case of a cast iron pipe, the instructions are slightly different:

• It is necessary to make a shallow cut around the perimeter;
• After this, use a chisel and hammer to “tap” this cut;
• At a certain point, the pipe should burst according to the markings.

How to cut a pipe smoothly with a grinder

When working with construction or plumbing tasks, you need to know how to cut a pipe evenly with a grinder. In this article we will look at quick and easy ways of how to properly cut a pipe with a grinder so that the result is perfect.

Methods for cutting large diameter pipes

For cutting large diameter pipes, such as sewer pipes, there are a number of reliable tools available. Next, let's look at some of them in detail:

• The grinder is an inexpensive and accessible option, but it is considered not the safest when working with such materials. If you decide to use this method, be careful and use protective equipment.
• A roller machine (pipe cutter) is a tool adapted for such manipulations. The device is attached and material removal begins. The clamping force is adjusted using mechanical devices. It is important to note that machine models differ in shape, so before use, consider the size relationship with the pipe.
• Gas cutting is the most popular option for cutting larger diameter pipes and sheet metal. The cut occurs due to the action of a high intensity flame, the metal melts and leaves the cut zone with a gas flow. This method is convenient and effective.

How to cut a pipe lengthwise correctly?

A quick way to cut a pipe lengthwise using a grinder:

How to cut a pipe evenly with a grinder

Precise pipe cutting looks simple at first glance. This task is quite problematic, especially if you need to make a cut at a certain angle or a cut of a complex configuration. You can do this either with your own hands or with the help of a specialized tool.

Much here depends on the diameter of the product, the wall thickness, the material from which the pipe is made and, of course, the tool itself.

What tools are there?

How to saw off a profile pipe smoothly with a grinder

Quite often, when performing various construction or repair work, it becomes necessary to cut a pipe. This could be plumbing work, laying pipelines or installing heating systems, but in any case it is necessary to know how to cut a pipe evenly. Some features of performing this task will be discussed further.

45 degree cutting

One particular example of such a situation is the need to cut a metal pipe at an angle of 45 degrees. Such cutting of material is often required when laying water pipes or heating systems. In this case, you have to deal with steel pipes.

For these purposes, conventional cylindrical pipes are usually used. If we are talking about the installation of some kind of metal structures, then profile pipes of rectangular or square cross-section are more often used.

The main problem here is that in order for the elements to be connected to coincide, the cut must be as smooth as possible, which means that especially close attention should be paid to marking the material.

In cases where cutting at an angle is required, a simple square sheet of paper can be used as a marking template. It must be folded strictly diagonally, and then wrapped around the pipe with the template.

In this case, it is necessary to carefully ensure that the side of the sheet, which is located closer to the end of the pipe, is perpendicular to its central axis.

Next, using marking material, a series of dotted lines is applied and after the marking is completed along the entire circumference, the template can be removed.

If you have to cut a profile pipe, then it is advisable to make a special template from the same pipe, but with a larger cross-section. In this case, you will only have to use the measuring devices once.

To apply markings you will need to use a protractor or a construction square. After sawing off the template, the pipes to be cut can simply be inserted into it and marked.

This approach will significantly save work time and cutting a profile pipe at 45 degrees will be convenient.

As for what to use when carrying out work, you should choose the most suitable and familiar one. This can be a simple hacksaw for metal, or a grinder with an installed cutting disc.

90 degree cutting

When the need arises to cut at 90 degrees, the situation is even simpler. In the case of cylindrical elements, you can use the same sheet of paper that is used to wrap the pipe as a template. It is important to ensure that the edge of the sheet is smooth and matches the entire circumference. After marking is applied, the element to be cut is fixed and the cut is made.

How to cut a profile pipe lengthwise or crosswise: marking and cutting methods

In households, profile pipes are widely used in the manufacture of greenhouses, greenhouses, canopies to protect vehicles from precipitation and other structures. When working with this material, it is useful to know how to cut a profile pipe along a line or crosswise with the most accurate angle.

Among the large number of construction metal cutting tools, the leader in speed, ease of cutting and efficiency is the angle grinder (grinder), which is often present in the tool kit of any home craftsman. To cut a profile steel pipe using a grinder, you will need a regular metal disc and strict adherence to safety rules - breaking the disc into segments at high rotation speeds can lead to serious injuries.

Fig.1 Profile pipes in the household

How to cut a profile pipe straight across

Most often in households, a rectangular or square pipe metal profile with a wall thickness of no more than 3 mm is used, and cutting into separate sections is necessary when carrying out work on assembling welded frames.

To cut a pipe correctly, additional devices are used to mark and mark the cutting line; some of the devices serve as a support edge for the cutting disk.

The nuances of working with a rectangular section

Rectangular workpieces are much easier to cut lengthwise and crosswise at any angles than cylindrical elements, which are difficult to hold stationary on a flat surface.

Transverse cutting of workpieces at any angle does not present any particular difficulties - the line of the required angular slope is drawn on the side edge and always coincides with the calculated one (round elements require the use of special patterns, calculated on a computer, to align their edges at an angle other than a straight line).

The thickness of the walls of a metal profile when used in households rarely exceeds 5 mm - it is easy to cut using an angle grinder with any metal disc.

Rice. 2 Types of transverse marking methods

What tool is used

As noted above, the main tool for cutting metal parts at home is an angle grinder; if you don’t have one, you can use a hand-held hacksaw or a jigsaw, which can also cut metal materials with a special diamond-coated blade.

For cutting with a grinder, cut-off electrocorundum discs are used, which are not intended for grinding operations. As an auxiliary tool, a tape measure, a metal ruler, various types of clamps, pencils and markers for marking will be useful.

Paper pattern for pipe

Using a paper sheet is a simple method of marking a rectangular or square profile for precise cutting at an angle of 90 or 45 degrees towards its axis.

To make markings for cross cutting at an angle of 90 degrees, take a sheet of paper and wrap it around the pipe until the edges line up exactly, after which they are glued together. With this method, the cutting line is very clearly visible, unlike drawing it with a pencil or marker along the edge of the template.

After this, the profile is cut along the template edge alternately from all sides, trying to avoid complete cutting of the finishing sections - this can lead to the disk hitting sharp corners and its destruction.

A sheet of paper can also be used to mark the side walls of rectangular or square pipes. To do this, the paper sheet is folded diagonally, and the resulting 45-degree angle is applied to the side walls and the appropriate markings are made. To ensure that the side lines are at the same level, an acute angle is applied to the transverse line placed at an angle of 90 degrees to the axis, which is previously applied in the above manner.

Rice. 3 Using a steel template

Miter box for cutting pipes

It is very convenient to cut a profile pipe using a special template, which is an analogue of a construction miter box for cutting building materials at different angles.

To do this, using the above or another method, a metal template is made from a piece of profile pipe cut along the length; it can be designed to obtain a right angle or an angle of 45 degrees.

To cut a metal profile, apply a template to it and draw a line with a scriber, along which a cut is then made. In other cases, the template is held and a grinder is used to draw a line along the surface of the workpiece, trying to avoid strong pressing of the side surface of the disk against the attached metal template. Then the template is removed and cutting continues along a clearly visible depression on the edges of the workpiece.

Using a template, you can get a very straight cut line if you do not hold it manually, but secure it to the workpiece using clamps or mounting bolts.

To make your own fasteners, drill a hole in the side surface of the U-shaped plate of the template and weld a union nut at this point from the outside into which the bolt is screwed.

To secure the template, place it on the part to be cut and screw in the bolt, pressing the template surface against the workpiece, then use a grinder with a metal disc to make a cut, lightly touching the guide edge.

Rice. 4 How to cut a workpiece with a homemade machine

Other options

A good option for making a template is to use a short piece of larger diameter pipe for marking, the guide edge of which has been pre-cut at the desired angles. When marking, the part is placed on the pipe to be cut, after which its surface is marked with a marker or scriber. The second method is to rigidly fix the template on the workpiece using wedges or clamps, followed by cutting with a metal disc with light pressure on the side surface of the template part.

In order not to cut metal pipes or sheets of iron by eye, some home craftsmen use homemade fastening devices for the grinder, rigidly securing it to a vertically mounted spindle. When moving the tool from top to bottom, a stable, even cut occurs on the part located under the disk; if metal guides are fastened to the machine bed, then when a workpiece is applied to them, any desired cutting angle can be obtained.

Fig.5 Working with thick-walled steel

Cutting large diameter profile pipe

A large-diameter metal profile has thick walls and a lot of weight; if for cutting thin-walled parts (wall thickness up to 2 mm) it was possible to use thin disks of about 1 mm in size, then for cutting thick-walled metal they take 2 mm.

disc circles.

Accordingly, it is more convenient to cut thick walls with a large-diameter disk using a powerful large-sized construction angle grinder - household devices do not have enough power to quickly carry out work, and their small disks quickly wear down.

How to Correctly Cut a Pipe with a Grinder

Announcements

How to cut a pipe evenly with a grinder?

When working with construction or plumbing problems, you need to know how to cut a pipe evenly with a grinder . In the article we will look at quick and easy methods of how to properly cut a pipe with a grinder so that the result comes out flawless.

Cutting pipe at an angle of 45 and 90 degrees

If it is necessary to cut the pipe at an angle of 45 degrees, which is often required when laying water and heating pipes. Iron and cast iron pipes that have a cylindrical shape are often used. For installation work, rectangular or profile pipes are used. But you should cut the pipe correctly with a grinder so that you can connect it later without any problems. Therefore, you should carefully mark the pipe.

Some craftsmen try to mark the cutting area using a tape measure, but we warn you that the result, in my opinion, will not be good. For a good result, consider the following recommendations from experts.

Take a sheet of paper or cardboard, preferably A4, fold it at an angle and wrap it around the pipe where you plan to make an even cut. The edges of the paper must be completely aligned. And the side of the paper that was closer to the end of the pipe was perpendicular to the axis. Then mark a cutting line in a circle.

If you need to cut at an angle of 90 degrees, then solve the problem quickly using paper or masking tape. Wrap it around the pipe so that the ends match. Make even markings and saw off.

How to cut a profile pipe evenly?

Craftsmen recommend using a square when cutting a profile pipe. For this purpose, apply the square to the sides one by one, and turn and apply marks with smooth movements. After the steps, secure the pipe and cut. Prepare a template for yourself that will be needed later and will save time. It is better to create the action with a grinder, so the cut will be smoother.

How to cut a cast iron pipe?

When working with a metal pipe, keep in mind that it is a fragile material. Therefore, we will develop a method that would allow us to cut such metal without damage.

Before work, make notes for the cut, just like when working with iron pipes. Place a wooden beam for support. Walk the grinder around the circumference of the pipe, making small cuts. Later, take the chisels, stick them into the groove and hit them hard with a hammer. Keep in mind that for cutting metal pipes, cutting discs on a bakelite base are used.

How to cut a pipe with a grinder ! Preparation for welding!

Here you will clearly see how simple and easy it is to prepare a perfect pipe for welding!!!

If you don’t have a grinder at home to cut a cast iron sewer pipe or other purposes, use a hacksaw, chisels or special pipe cutters.

How to cut a gas pipe?

Cutting a gas pipe is a dangerous action, so it is best to leave it to the experts. If you are convinced that he is capable, then to cut metal, take a grinder, welding, hacksaw, or gas welding.

• Before the start of the working day, turn off the gas supply riser. Then release the rest of the gas from the pipe. For this purpose, light the gas in the burners and wait for it to go out.
• After these steps, cut. Using the welding method, the iron base burns when exposed to extreme temperatures. The result is quick and effective. If cutting or rooting gas pipes again requires experience.

Methods for cutting huge diameter pipes

There are a number of reliable tools for cutting huge diameter pipes, such as sewer pipes. Next, let's take a closer look at some of them:

• The grinder is a cheap and affordable option, but it is not considered the most dangerous when working with such materials. If you dare to use this method, be careful and use protective equipment.
• A roller machine (pipe cutter) is a tool adapted for similar manipulations. The device is attached and material removal begins. The clamping force is adjusted using mechanical devices. It is important to note that machine models differ in shape, so before implementation, take into account the size ratio with the pipe.
• Gas cutting is a more popular option for cutting larger diameter pipes and sheet metal. The cut occurs due to the action of a flame of the highest intensity, the metal melts and leaves the cut zone with a gas flow. This method is successful and effective.

How to cut a pipe lengthwise correctly?

A quick method to cut a pipe lengthwise using a grinder:

• Pay main attention to the markings.
• For this option, use the painting thread that was found when marking the walls.
• Before starting work, secure the pipe and, using small movements, painstakingly saw the pipe.
• It’s better not to rush, but delicately and slowly process the pipe parts, so the cutting disc will not jump off the marking lines. Remember safety precautions.

How to cut thin-walled pipes?

Thin-walled pipes are made of non-ferrous metals: aluminum, copper. Such work should be created delicately, because there is a high possibility of deformation of the material. For cutting, fillers are used, for example, sand. There is an option to carry out the work using a grinder or a special machine.

To summarize, we emphasize that cutting iron pipes is not an easy process, but anyone can do it better if they want. Using expert advice, you can easily cope with cutting pipes of various sizes and materials.

Also, do not forget to process the edges of the pipes after the cut with ratfil or sandpaper. And most importantly, you must keep this fact in mind when starting such actions; this is safety precautions. When starting work, wear a special suit (casing), a mask or closed-type glasses.

Your hands are also strongly protected from sparks, so use thick gloves.

How to cut a pipe evenly with a grinder

Cutting pipes is a fairly simple operation, but correct cutting of pipes, when the cut is located exactly at right angles to the surface of the product, is a responsible procedure.

However, I am not talking about cutting large diameter pipes. Indeed, in this case, to ensure proper welding or gluing, it is necessary to maintain an angle of 90 degrees.

For individual use

This category of tools is used in private and small commercial construction for the installation of pipeline systems (plumbing, heating, sewerage, ventilation) of small diameter.

Personally, in my practice I used the following devices:

Pruning cutters. Used for cutting polymer pipes with a diameter of up to 75 mm.

To provide the necessary force, the devices are equipped with a gear mechanism. Before cutting a metal-plastic pipe (or a polypropylene product), it must be placed on a special shelf. The design feature of the pruning shears will not allow the part to be installed crookedly, so the cut will always be made at a right angle to the surface.

Disc pipe cutter. A device for cutting pipes, in which the cutting part is made in the form of a disk made of very durable material with sharpened edges. It is pressed against the pipe wall with a lever and pulled around the entire circumference.

I use a disc pipe cutter to cut PVC pipes from which internal and external sewerage is constructed. It cannot be used for metal-plastic, since the applied force will cause the thin-walled material to crumple.

Guillotine. You can imagine the design features and operating principle of this cutting device if you have seen the execution instrument used in medieval France.

There is a knife on top, which is lowered along guides onto the pipe located below. Most often I used such a device for cutting a large number of pipes and the unit was equipped with an electric drive. However, models with a screw are available for sale.

Hacksaw for metal. Suitable for cutting pipes from any materials into required lengths. My grandfather taught me to use it. The special secret here is to apply strictly measured force, otherwise the canvas will break.

After making a cut with a hacksaw, burrs form at the end of the pipe. You need to get rid of them using a shaver or file. Otherwise, the pipe connection may not be airtight.

Angle grinder. We are talking, if anyone doesn’t know, about an ordinary grinder. A special cutting disc is placed on it, after which you can cut pipes of both small and large diameters.

As with a hacksaw, a grinder can work with any material: from plastic to metal and cast iron.

Jigsaw. This tool can also cut pipes, but even I, a person with considerable experience, was not always able to make a cut at a right angle.

Cutting technology

I’ll say right away that if you are going to make a plumbing or heating system from polypropylene or metal-plastic, it is better to immediately buy pruning shears. It's inexpensive, but makes the job a lot easier.

In all other cases, you can use improvised means.

Right angle

To cut a pipe at a 90 degree angle, I suggest marking it before cutting. To do this, you will not need a marker or pencil, as you might think, but a piece of paper or masking tape. I prefer the latter option as it sticks to the surface.

So, I’ll tell you the operation scheme:

• I measure the required length of pipe and place a small mark in the right place with a pencil or black marker.

First you need to mark the cut location.

• Then, focusing on the mark, I stick the tape. It is important to do everything so that the edges of the paper tape meet with maximum accuracy. If it works, then you can be sure that the cut will be made correctly.

Instead of tape, you can use Pipe Wrap tape.

• I then secure the pipe so it doesn't move while cutting. It is best to clamp the part in a vice or press it against a flat surface with something.

Before cutting, the pipe must be carefully secured.

To avoid pinching the cutting disc during the operation, the second end of the pipe must be left suspended, and the cut must be started from the top of the pipe.

• After this, all that remains is to make the cut using a grinder. You must make sure that the cutting disc runs exactly along the edge of the masking tape that you pasted earlier.

If the pipe has a large diameter, you need to cut the wall itself in separate sectors, gradually turning the pipe to the desired side.

Large diameter pipes are cut into sectors.

You need to deal a little differently with a cast iron pipe, which can split if cut incorrectly. In this case, I personally proceed like this:

• I cut the product along the entire diameter;
• then I take a chisel and tap the cut;
• from such an impact the product should burst along the depression made by the disk.

Oblique cut

Now I’ll tell you how to cut a pipe at 45 degrees. In this case, you can also use markup.

The scheme is like this:

• I take a square sheet of paper (the side of the square should be equal to the outer diameter of the pipe);
• I fold it diagonally;
• I wrap it around the pipe and secure it.

Marking the cutting line using a sheet of paper folded diagonally.

In this case, if you make a cut along the oblique edge of a paper sheet, the end will have an angle of 45 degrees.

But it is best not to philosophize, but to use an ordinary miter box, which is intended precisely for such cases. Structurally, the device I mentioned has the shape of an inverted letter P, the opposite slats of which have cuts at the desired angle.

Homemade universal pipe cutter from a grinder

To cut round pipes of different diameters, the master suggests making and using in the future a homemade universal pipe cutter from a grinder.

Of course, it will be easier for someone to cut the pipe evenly without this device. But for beginners who do not yet know how to properly handle an angle grinder, this homemade product may come in handy.

To make a universal pipe cutter, the author uses a 50*50 mm angle, four 201 bearings, four 6000 bearings, a piece of M12 pin and a piece of M10 pin.

Also, in the process of making a homemade product, some other materials may be required.

Main stages of work

First of all, from a construction corner 50x50 mm, you need to cut a workpiece 300 mm long.

Next, along the edges of the corner, the author cuts out “windows” so that the bearings can be installed later.

From the M12 stud it will be necessary to cut two blanks 28 cm long. The author puts bearings on them. Then the studs need to be welded to the corner.

The author cuts a piece of the required length from a 50x30 mm profile pipe and also welds it to the corner. A piece of sheet metal 4 mm thick is used as the base.

A corner will be attached to the metal plate, as well as a pendulum for the angle grinder based on housing bearings.

You will also need to make a mount for the grinder. To do this, you can use available materials.

Using a 25*25 mm profile pipe, the author connects the angle grinder mount to the pendulum.

The final part of the work

At the last stage, it remains to cut off another piece of the corner, which will fix the pipe during the cutting process.

You will also need to cut out “windows” in the workpiece in order to install 6000 bearings in them.

Then the master makes a simple clamp from sections of the profile pipe, which will press the corner to the workpiece.

After welding, we clean all the seams, and the homemade product is ready for use.

In everyday life, we are constantly faced with the need to lay pipelines from various materials, be it water supply, sewerage, heating, installation of cable ducts, or even the construction of frame structures in a house or country house.

This article will tell you how to evenly cut a pipe for certain purposes, if you do all the work yourself, that is, it provides detailed instructions for all technological operations.

In addition, let's talk about the variety of tools for amateur or industrial use.

What tools are used to cut pipes?

At first glance, it may seem that cutting pipes is a fairly simple process that is not worth special mention. However, this is not quite true.

It’s one thing when you don’t need precise, even cuts at an angle of 90º or any other, since no further welding or joining of the ends will be performed. And it’s a completely different matter when you need to make an absolutely precise cut.

Note that if it is necessary to cut oblique ends with an exact angle, it is worth consulting with experienced craftsmen.

Separately, it is worth mentioning pipes with a large diameter, when joining which a cut of exactly 90º must be ensured. Be that as it may, all these operations are performed using special equipment.

Tools for home and semi-professional use

To install water supply or sewerage systems, heating and ventilation circuits in home construction or when providing construction services, tools from this category are often used.

Among the most common devices are:

1. Cutters with pruner design . This tool is used for cutting polymer pipes whose cross-section does not exceed 75 mm. The gear mechanism of the device allows you to apply the force necessary for work. The design of such a cutter includes a special shelf on which the pipe is laid, which ensures an even cut at exactly 90º. Prices for such tools can be very different, it all depends on their quality, dimensions, capabilities, manufacturer and other factors.
2. Disc type pipe cutter

How to cut a profile pipe lengthwise - cutting technology

If cross-cutting a profile does not cause any particular difficulties, then a longitudinal cut, which is necessary for some work in the household, is more complex due to its length.

One of the problems when carrying it out is the accuracy of the markings; to apply it in the center or at another point of the cut edge, marks are placed along the entire length at the same distance from the side wall and then they are connected with a pencil, marker or scriber, using an even corner, construction paper, as a guide. usually a level, a profile from drywall.

Rice. 6 Cutting a pipe lengthwise along a guide angle

In order to cut a metal profile in the longitudinal direction, they drive the angle grinder along the line, gradually cutting a through hole - the method is not very accurate, the tool has to be held suspended without support.

A more convenient way to qualitatively cut a workpiece longitudinally is to use auxiliary supports in the form of a metal corner or even straight plates. To do this, the corner is attached to the surface of the workpiece using clamps and the grinder is guided along its side edge; if the length of the template corner is small, it is unscrewed and moved further to a new place, after which cutting is resumed.

How to cut a pipe straight - common options

Precise pipe cutting looks simple at first glance. This task is quite problematic, especially if you need to make a cut at a certain angle or a cut of a complex configuration. You can do this either with your own hands or with the help of a specialized tool.

Much here depends on the diameter of the product, the wall thickness, the material from which the pipe is made and, of course, the tool itself.

Photo of a hand pruner.

What tools are there?

Pipe cutting tools, like most existing tools, come in manual and electric versions. Both of these niches, in turn, contain specialized professional and applied amateur tools (find out here how to cut threads on a pipe at home).

For example, the question of how to cut a metal-plastic pipe can be solved in two ways.

On the one hand, there is a professional pruner, but on the other hand, you can use a regular hacksaw.

Roller pipe cutter.

• If we talk about pipes made of various types of plastic, then for material with a cross-section of up to 75 mm, a lot of special scissors are produced; professionals call them pruning cutters . Since plastic material is quite dense, all pruners are equipped with a gear mechanism that serves to increase the compression force. The price for such scissors starts from $10 and, depending on the quality, can reach up to $150.
• The next professional in cutting plastic is the disc pipe cutter . If the pruner works on the principle of ordinary scissors, then the cut is made using a sharp, heavy-duty disc. He presses himself against the wall and, rolling around it, makes an incision.

A pipe cutter is indispensable for thin-walled products, since cutting a metal-plastic pipe with a thin wall with pruning shears is difficult because it wrinkles.

Knife for roller cutter.

• The question of how to evenly cut a large-diameter pipe is easily solved by professionals; for this purpose, there is a guillotine adapted for cutting round products . Its operating principle is classic, with a knife on top and a semicircular bed on the bottom.

The device can be electrically driven and cut using hydraulics. There is also a guillotine with a manual, screw drive.

• In addition, there are a lot of specialized machines . Thus, lathes are used for perpendicular cuts. If the question arises of how to cut a pipe at 45 degrees or at any other angle, then, as a rule, band saws are needed.

Manual cutting process.

Important: the main difference between a professional tool and an amateur one is that the cut is performed with extreme precision. Plus, the edge does not require additional processing after finishing the work.

• But the necessary device is not always at hand, and buying it separately is expensive and does not always make sense . The leader among amateur tools is considered to be an ordinary hacksaw. It can easily cope with both metal and plastic, the main thing is to mark it correctly, but more on that later.
• Every good owner always has an angle grinder . With its help, having a certain skill, you can quite accurately unravel pipes of small and medium diameter. The big advantage of the grinder is that it can be used to work on any material, from polyethylene to cast iron or steel.
• At the end of our rating is a jigsaw. It is undoubtedly possible to work with it, but it is difficult to make precise cuts, plus the edges of the pipe will need to be further refined.

Power tools for large diameter pipes.

Using a tool such as a pruning shear or a disc pipe cutter does not require special training; it is easy to work with them efficiently. It's a completely different matter when you have to use improvised means.

Working with a hacksaw.

Making a perpendicular cut

There are several opinions on the topic of how to cut a pipe at 90 degrees. As in any business, a lot depends on the correctness of the markings. The most reliable folk method is to use a paper sheet or masking tape.

It is easier to work with tape; you need to carefully, without creases or distortions, stick it around the perimeter of the pipe. If both sides of the strip meet clearly, without shifts, then you already have 90º.

The product must be securely fastened before cutting, otherwise the pipe will rotate and you will not be able to unravel it smoothly. Ideally, of course, it is better to clamp it in a vice, but at the dacha you don’t always have such luxury. A small diameter pipe can be tied to a stool or table.

Working as a grinder.

To a large-diameter product, you need to attach 2 wooden support bars in parallel, which will prevent the pipe from rotating. It is most convenient to fasten with tape; a few turns made on both sides of the cut will securely fix the product.

Advice: before cutting the pipe evenly with a grinder, in some cases it is better to fasten it only on one side, leaving the other hanging. You need to cut from top to bottom to avoid pinching the disc.

Guillotine for pipes.

Returning to how to cut a large-diameter pipe, it should be noted that with a hacksaw or grinder, such a product should be cut into sectors, gradually.

In the case of a cast iron pipe, the instructions are slightly different:

• It is necessary to make a shallow cut around the perimeter;
• After this, use a chisel and hammer to “tap” this cut;
• At a certain point, the pipe should burst according to the markings.

How to cut a pipe smoothly with a grinder

When working with construction or plumbing tasks, you need to know how to cut a pipe evenly with a grinder. In this article we will look at quick and easy ways of how to properly cut a pipe with a grinder so that the result is perfect.

Methods for cutting large diameter pipes

For cutting large diameter pipes, such as sewer pipes, there are a number of reliable tools available. Next, let's look at some of them in detail:

• The grinder is an inexpensive and accessible option, but it is considered not the safest when working with such materials. If you decide to use this method, be careful and use protective equipment.
• A roller machine (pipe cutter) is a tool adapted for such manipulations. The device is attached and material removal begins. The clamping force is adjusted using mechanical devices. It is important to note that machine models differ in shape, so before use, consider the size relationship with the pipe.
• Gas cutting is the most popular option for cutting larger diameter pipes and sheet metal. The cut occurs due to the action of a high intensity flame, the metal melts and leaves the cut zone with a gas flow. This method is convenient and effective.

How to cut a pipe lengthwise correctly?

A quick way to cut a pipe lengthwise using a grinder:

• Pay main attention to the markings.
• For this case, use painting thread, which is widely used when marking walls.
• Before starting work, secure the pipe and, using small movements, carefully saw the pipe.
• It’s better not to rush, but delicately and slowly process the parts of the pipe, so that the cutting disc does not jump off the marking lines. Remember safety precautions.

How to cut thin-walled pipes?

Thin-walled pipes are made of non-ferrous metals: aluminum, copper. Such work should be done delicately, as there is a high probability of deformation of the material. For cutting, fillers such as sand are used. Actions can be carried out using a grinder or a special machine.

To summarize, we emphasize that cutting metal pipes is a complex process, but every willing craftsman can improve it. Using the advice of professionals, you can easily cope with cutting pipes of various sizes and materials.

Also, do not forget to process the edges of the pipes after cutting with a file or sandpaper. And the most important thing to remember when starting such actions is safety precautions. When starting work, wear a special suit (casing), mask or closed-type glasses.

Your hands should also be reliably protected from sparks, so use thick gloves.

Methods for marking and cutting metal pipes

Methods for marking and cutting metal pipes

The use of [metal pipes] in the production and installation of metal structures involves the need for cutting across, along and at an angle. And you don’t always have special equipment at hand. We will describe in this article how to cut a pipe evenly using available tools.  

Methods for cutting metal pipes at an angle 

Methods for cutting metal pipes at an angle 

There are several ways to saw off a pipe or cut it into pieces. Of the available tools, a grinder is the best for this task. But the biggest problem remains the need to correctly mark the cutting lines. They can be different, most often you have to maintain either a right angle relative to the axis of the pipe, or 45 degrees. The techniques vary somewhat depending on what products need to be cut:

• pipes for laying water supply, gas and for heating distribution;
• profile products for assembling gates, canopies, and other metal structures;
• large-diameter pipes - as a rule, this is rarely needed at home, where the widest clearance is only in the sewer system;
• pipes made of steel, cast iron, thin-walled of non-ferrous metals and soft alloys. 

Both problems can be solved quite simply even without the use of a special pipe angle pattern. 

IMPORTANT TO KNOW: Steel water and gas pipe

We cut the pipe at an angle of 90 degrees

To mark the cut [of water and gas pipes] at a right angle, you can use a sheet of standard A4 paper, wide electrical tape or construction tape. If you wrap a wide enough material around the pipe so that the edges line up exactly when applied, you will get a perfect cutting line. If the tape or tape is firmly stuck to the metal, you can go right along the edge.  

It is important to be able to use the grinder correctly, hold it with a certain force and follow safety rules. The technique described is the simplest; it is also suitable for cutting a large diameter pipe.

We cut the pipe at an angle of 45 degrees 

Most often this has to be done when installing plumbing and heating and assembling frame structures. You can cut the pipe at 45 degrees with a grinder according to the markings, which are made either with a sheet of paper of the same A4 size, or using a regular school (drawing) isosceles square.  

Use a sheet of paper or cardboard

You will have to do several operations with the sheet to get the desired angle. If you don't want to get confused with the folds, just make it square and fold it diagonally to get the angle you want. The same can be done with any sheet, as long as its sides are equal to each other. The method is convenient in that it can be applied to both large-diameter pipes and [profile pipes of square and rectangular cross-section].  

IMPORTANT TO KNOW: Profile stainless pipe

Marking with a square 

Marking with a square 

If you have a square at hand, you must first determine the exact line of the end of the pipe, including the profile one. By applying the tool and smoothly moving it along the surface, we get a cutting line of 45 degrees. The same technique is used with a 30 degree square.  

How to properly cut pipes from different metals 

How to properly cut pipes from different metals 

Accurate cutting and trimming of pipes depends not only on well-executed markings. The material is also of great importance - metal of different thicknesses and hardness is cut with different forces and side effects. To properly cut a cast iron pipe, it should not be sawed all the way through. Cast iron is a brittle metal, so several cuts are usually made, and then a specialist knocks a piece out of them with one precise blow of a chisel.  

To work with thin-walled pipes, you will have to very accurately check the position of the grinder. At the same time, the master must choose the right [discs for cutting metal with a grinder]. In industrial settings, special pipe cutters, gas cutting machines and welding machines can be used to perform the same tasks.  

IMPORTANT TO KNOW: Seamless cold-formed pipes

Safety when cutting a gas pipe 

Safety when cutting a gas pipe 

When working with gas pipes connected to the mains, it is important to follow safety precautions. First turn off the gas supply valve, then make sure that there is nothing in the pipe. To do this, just open the stove burners and light the gas - when it runs out, the flame goes out.

How to cut a pipe evenly with a grinder at 45 and 90 degrees | Cutting methods

When working with construction or plumbing tasks, you need to know how to cut a pipe evenly with a grinder. In this article we will look at quick and easy ways of how to properly cut a pipe with a grinder so that the result is perfect.

Cutting pipe at an angle of 45 and 90 degrees

Cutting pipe at an angle of 45 and 90 degrees

If you need to cut a pipe at an angle of 45 degrees, which is often required when laying water and heating pipes. Often steel and cast iron pipes that have a cylindrical shape are used. In installation work, rectangular or profile pipes are used. However, you should cut the pipe correctly with a grinder so that you can easily connect it later. Therefore, you should carefully mark the pipe.

Some craftsmen try to mark the cutting area using a tape measure, but we warn you that the result will most likely be negative. And for a positive result, consider the following recommendation from professionals.

Take a sheet of paper or cardboard, preferably A4, fold it diagonally and wrap it around the pipe where you plan to make an even cut. The edges of the paper must be absolutely aligned with each other. And the side of the paper that is closer to the end of the pipe was perpendicular to the axis. Then mark a cutting line in a circle.

If you need to cut exactly at an angle of 90 degrees, then solve the problem quickly using paper or masking tape. Wrap it around the pipe so that the ends match. Make an even mark and saw off.

How to cut a profile pipe evenly?

Craftsmen advise using a square when cutting a profile pipe. To do this, apply the square to the sides one by one, and turn and apply marks with smooth movements. After the steps, secure the pipe and cut. Prepare yourself a template that will be useful in the future and will save time. It is better to carry out the action with a grinder, so the cut will be smoother.

How to cut a cast iron pipe?

When working with cast iron pipe, keep in mind that it is a fragile material. Therefore, we will find a way to cut such metal without damage.

Before starting work, make notes for the cut, as you would when working with steel pipes. Place a wooden beam for support. Run a grinder around the circumference of the pipe, making small cuts. Then take the chisels, insert them into the groove and hit them hard with a hammer. Please note that Bakelite-based cutting discs are used to cut cast iron pipes.

If you don’t have a grinder at hand to cut a cast-iron sewer pipe or other purposes, use a hacksaw, chisels or special pipe cutters.

How to cut a gas pipe?

Cutting a gas pipe is a dangerous action, so it is best to leave it to professionals. But if you are confident in your abilities, then use a grinder, welding, hacksaw, or gas welding to cut metal.

Trimming instructions:

• Before work, turn off the gas supply riser. Then release the rest of the gas from the pipe. To do this, light the gas in the burners and wait for it to go out.
• After these steps, cut. Using a welding method, the metal base burns when exposed to high temperature. The result is fast and effective. But remember that cutting or rooting gas pipes again requires experience.

How to cut a pipe evenly with a grinder

How to cut a pipe evenly with a grinder

Precise pipe cutting looks simple at first glance. This task is quite problematic, especially if you need to make a cut at a certain angle or a cut of a complex configuration. You can do this either with your own hands or with the help of a specialized tool.

Much here depends on the diameter of the product, the wall thickness, the material from which the pipe is made and, of course, the tool itself.

What tools are there?

What tools are there?

Pipe cutting tools, like most existing tools, come in manual and electric versions. Both of these niches, in turn, contain specialized professional and applied amateur tools (find out here how to cut threads on a pipe at home).

For example, the question of how to cut a metal-plastic pipe can be solved in two ways.

On the one hand, there is a professional pruner, but on the other hand, you can use a regular hacksaw.

• If we talk about pipes made of various types of plastic, then for material with a cross-section of up to 75 mm, a lot of special scissors are produced; professionals call them pruning cutters . Since plastic material is quite dense, all pruners are equipped with a gear mechanism that serves to increase the compression force. The price for such scissors starts from $10 and, depending on the quality, can reach up to $150.
• The next professional in cutting plastic is the disc pipe cutter . If the pruner works on the principle of ordinary scissors, then the cut is made using a sharp, heavy-duty disc. He presses himself against the wall and, rolling around it, makes an incision.

A pipe cutter is indispensable for thin-walled products, since cutting a metal-plastic pipe with a thin wall with pruning shears is difficult because it wrinkles.

• The question of how to evenly cut a large-diameter pipe is easily solved by professionals; for this purpose, there is a guillotine adapted for cutting round products . Its operating principle is classic, with a knife on top and a semicircular bed on the bottom.

The device can be electrically driven and cut using hydraulics. There is also a guillotine with a manual, screw drive.

• In addition, there are a lot of specialized machines . Thus, lathes are used for perpendicular cuts. If the question arises of how to cut a pipe at 45 degrees or at any other angle, then, as a rule, band saws are needed.

Important: the main difference between a professional tool and an amateur one is that the cut is performed with extreme precision. Plus, the edge does not require additional processing after finishing the work.

• But the necessary device is not always at hand, and buying it separately is expensive and does not always make sense . The leader among amateur tools is considered to be an ordinary hacksaw. It can easily cope with both metal and plastic, the main thing is to mark it correctly, but more on that later.
• Every good owner always has an angle grinder . With its help, having a certain skill, you can quite accurately unravel pipes of small and medium diameter. The big advantage of the grinder is that it can be used to work on any material, from polyethylene to cast iron or steel.
• At the end of our rating is a jigsaw. It is undoubtedly possible to work with it, but it is difficult to make precise cuts, plus the edges of the pipe will need to be further refined.

Some tips for cutting pipes

Using a tool such as a pruning shear or a disc pipe cutter does not require special training; it is easy to work with them efficiently. It's a completely different matter when you have to use improvised means.

Making a perpendicular cut

Making a perpendicular cut

There are several opinions on the topic of how to cut a pipe at 90 degrees. As in any business, a lot depends on the correctness of the markings. The most reliable folk method is to use a paper sheet or masking tape.

It is easier to work with tape; you need to carefully, without creases or distortions, stick it around the perimeter of the pipe. If both sides of the strip meet clearly, without shifts, then you already have 90º.

The product must be securely fastened before cutting, otherwise the pipe will rotate and you will not be able to unravel it smoothly. Ideally, of course, it is better to clamp it in a vice, but at the dacha you don’t always have such luxury. A small diameter pipe can be tied to a stool or table.

To a large-diameter product, you need to attach 2 wooden support bars in parallel, which will prevent the pipe from rotating. It is most convenient to fasten with tape; a few turns made on both sides of the cut will securely fix the product.

Advice: before cutting the pipe evenly with a grinder, in some cases it is better to fasten it only on one side, leaving the other hanging. You need to cut from top to bottom to avoid pinching the disc.

Returning to how to cut a large-diameter pipe, it should be noted that with a hacksaw or grinder, such a product should be cut into sectors, gradually.

In the case of a cast iron pipe, the instructions are slightly different:

• It is necessary to make a shallow cut around the perimeter;
• After this, use a chisel and hammer to “tap” this cut;
• At a certain point, the pipe should burst according to the markings.
