How to cut a profile pipe evenly

How to cut a profile pipe evenly

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

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.

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.

How to mark a pipe straight along

Pipes are a widely used building material. They are used in the installation of various systems. A common occurrence during the installation process is when pipes need to be joined at an angle. However, the technology for producing such work does not seem quite common.

To create this connection configuration, the pipes must be cut at an angle. Let's look at how such operations are performed and what cutting methods exist.

Techniques for cutting pipes at an angle

When considering work methods—cutting straight or at an angle—one should take into account the different materials of the products being processed. Thus, hoses made of polypropylene or thin copper are easier and easier to cut than thick-walled steel pipes.

Plastic products of small diameters are cut at the desired angle using special scissors. In this case, you can control the angle with a regular protractor.

It is necessary to cut pipes very often when working with these installation elements. A popular tool for such cases is the so-called grinder. This tool can be used to cut straight and at an angle.

The most common installation need is cutting water or other pipes at an angle of 45º. Let's find out what devices can be used for cutting at this and other angles.

Paper pattern for pipe

To perform a relatively accurate cut, you can use a simple technique, where an ordinary sheet of paper acts as a kind of pattern. For example, A4 printer paper is well suited for creating patterns. The sheet is first marked into a square using a ruler. The diagonal size of the square should be equal to the circumference of the pipe that needs to be cut. Excess parts of the sheet are cut off.

The simplest way to obtain a marking line on a pipe for making a cut at an angle of 45 degrees. A regular sheet of paper is used, which is placed on the pipe body in the cutting area

Next are the following steps:

1. Bend the sheet diagonally, aligning opposite corners.
2. Rotate the resulting triangle so that the hypotenuse line is perpendicular to the axis of the pipe.
3. In this position, wrap the tube surface with paper, aligning the extreme points of the hypotenuse together.
4. Use a marker to mark the cut along the line of any of the legs of the triangle.
5. Cut the pipe along the marked line.

This method is quite convenient for marking and cutting pipes at an angle of 45º in the diameter range from 32 to 63 mm. For greater ease of marking, it is recommended to use thick but soft paper. You can also use paronite and similar materials.

Programs for calculating cutting angles

Pattern cutting technology allows you to obtain different cutting angles. But to form a pattern at angles other than 45º, you will need to perform mathematical calculations and cut out a template from paper or similar materials based on the calculated data. True, there are computer programs designed to save the master from making calculations. Patterns for cutting pipes are printed by such programs on a printer.

This is what the window of a computer program looks like when calculating the cutting angle for a circular section. Based on the calculation results, a pattern is drawn that can be printed.

A template is cut out according to the pattern

A simple calculation program created on the basis of the MS Excel application allows you to calculate and draw up a pattern for almost any pipe diameter and required cutting angle.

All the user needs to do is enter the appropriate values ​​in the “Outer diameter” and “Cut angle” cells. Using these parameters, a pattern will be generated that can be sent for printing.

An example of a pattern obtained by calculation in the popular Excel program. The calculation of the curve passage points is carried out on the basis of only two specified parameters - the pipe diameter and the required cut angle

The disadvantage of the program is that it does not take into account the thickness of the pattern sheet, which leads to minor inaccuracies.

Miter box for cutting pipes

There is a simple tool that is often used in everyday life, mainly for working with wood. It's called a miter box. So, this same device is suitable for cutting pipes, and at different angles. The miter box is commercially available, but if you wish, you can always make it yourself and adjust the structure to the desired pipe diameter:

1. Take a wooden board with a width equal to the diameter of the pipe and a length of 400-500 mm.
2. Take two more boards of the same dimensions, but increased in width by the thickness of the first board.
3. From three boards, assemble a structure in the form of an inverted letter “P”, where the first board is installed as the base.
4. In the central part of the structure, mark a rectangle, two sides of which run along the inner boundaries of the side boards.
5. Divide the rectangle with diagonals and, along the lines obtained on the upper edges of the side boards, make cuts down to the base.

  Laying depth of sewer pipes in a private house

In this way, a template is made for cutting at an angle of 45º. But with the help of a protractor you can mark almost any angle and make cuts to cut the pipe for a specific angle. The advantage of a miter box is that the tool is suitable for repeated use. Working with the tool is permissible until the walls of the slots are worn to such a degree that they can provide high cutting accuracy. It is recommended to make the walls of the instrument from a material of higher strength than wood.

This is what a possible design of a miter box looks like - a device that can also help cut pipes at different angles.

However, a miter box is, as a rule, convenient to use for cutting pipes of small diameters and with small wall thickness

The advantages of the method are obvious - simplicity, ease of making a tool (miter box), efficiency, versatility.

The disadvantages of working with this type of equipment are the need to adjust the dimensions of the miter box to the pipe diameter, provided that an accurate cut is performed. That is, for each pipe you will have to make your own tool.

Also, using a miter box, you can only cut a pipe with a hacksaw or pruning shears (for plastic products). This tool is not suitable for working with thick-walled metal pipes for cutting with a grinder.

Simple cutting equipment

Metal products of round and rectangular shapes with fairly thick walls can be conveniently cut at an angle using simple electromechanical equipment. The cutting element of such a tool is a cutting disc or circular saw mounted on the electric motor shaft. In turn, the electric motor with the cutter is part of the entire equipment, which includes a work table, a pendulum support, and a clamp.

An electromechanical device for cutting pipe elements, including at different angles. A disc cutter and a simple mechanical system for fastening the pipe in different positions are used.

To install the pipe at the desired angle and then fasten it, a regular clamp and two metal corners are used. One corner (short) is attached to the base of the rotating mechanism - the pendulum. The second corner (long) is in a free state.

Pipe laying and cutting procedure:

1. The rotating mechanism sets the required cutting angle (for example, using a ruler and a protractor).
2. The found position is fixed with clamping screws.
3. A pipe is placed between the short and long corners and pressed with a clamp screw.
4. Voltage is supplied to the electric motor.
5. By applying a slight pressure force to the cutter disk, the pipe is cut in the right place.

The advantages of this technique are fast work, accurate cutting, and the ability to process a large number of pipes in a short period of time. Disadvantages: restrictions for use in domestic conditions, increased noise, work with pipes of only small and medium diameters. In addition, the cutting process with equipment is performed stationary at a distance from the installation site, which is not always acceptable.

The nuances of working with a rectangular section

To cut rectangular products, it is recommended to prepare template corner cuts in advance. They can be easily made from a metal corner, having previously been marked with the same protractor.

Cutting rectangular pipes (profile elements) at the desired angles is usually performed using templates. Such templates are made from metal corners of different sizes.

Marking can be done at different angles. To use a template, just attach it to the rectangular pipe in the right place and mark the cutting line. Then use any suitable tool to make a cut along the intended line.

Precision cutting devices

Among branded devices that could be used in everyday life to make cuts at an angle, you can pay attention to Italian-made equipment. The Mini Cut band saw from the MASS company is a small-sized device with manual clamping, for working not only with pipes, but also with angles, rods, and profile elements.

A convenient and productive device for cutting pipes of small and medium diameters. The cutter is made on the basis of a steel strip, which can be installed to make cuts at an angle

The machine supports setting the cutting angle from 0 to 45º.

The procedure is carried out using a tape at a speed of 45 reciprocating movements per minute. The device is equipped with a 370 W electric motor, which is powered from a household network.

The maximum permissible diameter of a round pipe to be cut is 65 mm.

Industrial models (using the example of BSM)

There are special machines for industrial use to perform precise miter cutting operations. A good example: devices produced under the BSM brand. The machine manufacturer is the German company Rexinger. True, the BSM series machines are designed exclusively for working with polypropylene pipes of fairly large diameters. Processing of products such as PP, PVC, PE, PVDF is supported.

Industrial machine for cutting pipe products made of polymers. Designed to work with large diameter products, but has equipment for processing pipes from 50 mm.

The machine provides cutting in a wide range of angles

The cutting tool of the machine is a band saw, thanks to which cuts are made at angles from 0 to 67.5º. The accuracy of the process is ensured by a laser cutting recognizer.

Despite the configuration of the device for large-diameter products, you can use a special table, which can also be used to successfully cut pipes of small diameters (50 - 200 mm). A wide range of BSM devices is produced.

  Adapters for PVC sewer pipes

Application of thermal methods

In addition to mechanical methods, thermal methods are often used, where welding or cutting machines are used as tools. For example, an autogenous gas cutter or a conventional welding machine (DC/AC). With the help of such machines, thick-walled metal pipes can be cut. However, it is extremely difficult to obtain a perfectly even, high-quality cut using electric welding or gas autogen.

Cutting technology using electric welding and autogen is widespread everywhere. The technique does not provide high cutting accuracy, but when installing pipes this factor is often not decisive

Typically, after thermal cutting, products undergo additional processing.

The cut line is aligned and the required angle values ​​are adjusted. This approach is economically unprofitable, as it is accompanied by additional costs for mechanical processing. As a rule, thermal cutting techniques are used in industrial production conditions.

True, housing and communal services also often resort to this technique.

Thermal cutting is also used to work with plastic materials. There are devices - thermal guillotines. The sharp thin blade of such devices is heated to a high temperature, after which the cut is performed.

Thermal guillotines support cutting at an angle, and this is their advantage. However, these devices cannot be used to work with materials that are more rigid than polyvinyl chloride, wood, or chipboards.

Conclusions and useful video on the topic

The video presents calculations and shows a workshop on cutting a pipe at angles of 45 and 90:

For each individual installation case, you can choose the most convenient and less expensive cutting method. The specific choice depends on the pipe material, its diameter, and wall thickness. Using simple marking methods, you can get a fairly accurate angle at which you want to cut the workpiece. At the same time, using a complex calculation technique, it is possible to cut at non-standard angles with high accuracy.

Miter cutting

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

It's not the gods who burn the pots!

When you have all the necessary tools at your disposal, you don’t think about how difficult it is to correctly perform certain routine operations. For example, do you know how to cut a pipe evenly with a grinder? It was this request that my neighbor in the garage came to me with, who, unlike me, was not used to doing much with his own hands.

It turns out that after dismantling the water supply in his apartment, he was left with a large number of unnecessary pipes, from which his wife decided to make a greenhouse in the country. I don’t know why he needed to cut the parts exactly straight, but I gave him all the necessary recommendations.

And at the same time, I thought that other people who do not have a professional pipe cutter in their arsenal would need instructions that describe how to cut a pipe at 90 degrees. That is why I have prepared the material that I bring to your attention today.

Tools used

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. And if you have to cut the parts of the engineering system at a different angle, then there is no way to do it without consulting an experienced builder (I will modestly keep silent about myself).

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.

There is special equipment for any cutting operation. This is what I want to talk about first.

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:

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

Pipe cutters allow you to make cuts quickly and correctly.

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.

The price of such products starts from 10 dollars and can reach up to 100. It depends on the manufacturer, material, size, and so on.

1. 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.

Large diameter pipes are cut with a disc pipe cutter.

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.

1. 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.

Guillotine with screw for even cutting of pipes.

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.

1. 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.

A hacksaw is the simplest tool for cutting pipes from any materials.

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.

1. 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.

A grinder in skillful hands turns into an effective pipe cutter.

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

1. 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.

A jigsaw also cuts pipes, but is it smooth?

Therefore, there is no need to hammer nails with a microscope; there are simpler cutting methods.

But first I want to tell you about the professional equipment used to cut pipes at industrial enterprises and when laying main water transport communications.

For industrial use

We seem to have figured out local and individual engineering systems, but the question remains of how to evenly cut a large-diameter pipe. In this case, special equipment (often stationary) comes to the rescue, with which professional builders work.

I once worked as a housing department foreman, so I had to deal with such units. I'll tell you about the most interesting ones:

1. Lathes. These units perform any processing of round pipeline parts, including those used for transporting aggressive liquids.

A lathe can cut pipes perfectly. And not just cut.

The maximum size of pipes processed depends on the cross-section of the spindle holes and the distance between the fastening heads. In addition to banal cutting, lathes can chamfer, cut pipes and perform other operations, including in automatic mode.

1. Band cutting machines. Used for cutting large diameter sewer and water pipes that are already laid in trenches (or placed in buildings).

Machine for cutting pipes laid in the ground.

The band cutter is capable of performing operations even on highly deformed products. In addition to direct cutting, the device can chamfer the desired shape.

1. Disc cutting machines. Used for processing metal parts, including non-ferrous metals. They can cut both round and profiled pipes of large diameter (section).

The cutting disc machine cuts the pipes into parts of the required length.

In most cases, such devices are part of a production line and are equipped with a device that collects and packages a certain number of identical pipes for shipment to customers.

1. Manual disc cutters. Used for cutting a large number of pipes from different materials directly at the installation site.

Manual disc cutter for pipes made of any materials.

These devices have a special clamping device that firmly holds the part during processing without deforming it. Therefore, you can cut metal, copper, and metal-plastic pipes.

Some cutters are equipped with a rotation system and orbital welding. That is, pipes can not only be cut, but also joined to each other.

Several years ago, I took part in the construction of a large shopping center, and if it weren’t for a manual disc cutter, my hands would have fallen off just from cutting pipes, not to mention soldering and welding them.

However, if you only have a greenhouse at your dacha ahead, you don’t need to buy anything special. Below I will tell you how to cut a pipe using the most common tools that, in my opinion, every thrifty owner has.

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:

1. 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.

1. 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.

1. 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.

1. 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.

Another simple way to apply markings is to lower the pipe at the desired angle into a bucket of water. In this case, the wet boundary will serve as a guide for cutting.

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.

How to cut a profile pipe at 45 degrees

When installing a pipeline, it is often necessary to cut the pipe at a certain angle. Accuracy plays a big role in this task. There are several simple ways to cut a pipe at an angle.

An incorrect pipe cut will make it impossible to install the structure of the shape that was originally intended. For example, if you plan to rotate the system by 45 degrees, then it is necessary to cut the pipe at 45 degrees. To complete the task, you will need marking tools and a grinder (it can be replaced with a hacksaw).

Marking a corner with a piece of paper

Marking with a paper sheet is one of the simplest ways to complete the task. A square sheet is required. It folds exactly diagonally. The resulting template for cutting pipes must be wrapped around the product so that the long side runs parallel to its cross-section.

Then an angle of 45 degrees is formed on the smaller side. All that remains is to mark the cut line using a construction pencil or marker on a sheet of paper.

It is recommended to wrap the marking area with narrow tape to prevent it from being accidentally erased. This method is excellent for long, large pipes with the cut location approximately in the middle of the product.

Method of marking using a container of water instead of a pattern

This marking method is suitable for small-diameter pipes that are planned to be cut at a certain angle close to the edge. First you need to prepare a deep container of water. The planned angle of inclination is marked on it. Now you need to carefully immerse the end of the product in the liquid, tilt it towards the mark, and then pull it out.

As a result of such actions, a clear line of contact with water will appear on it; it needs to be highlighted. The pipe is cut along it at an angle. This method is best suited for jobs that require multiple markings.

Using the computer program

To implement this method of marking pipes for cutting, you will need a computer with special programs. First, you need to draw up a drawing that shows the transverse dimensions of the product, as well as the planned cut angle. You need to get a virtual template.

How to cut a pipe at an angle of 45 or another 90 degrees

From time to time it is necessary to cut the pipe at 90 degrees, or two at 45 degrees. Here's my method. Link to the program Development.

Medicine plays a special role in science, because man, often not immortal, is fragile and very vulnerable to all kinds of diseases. Many people know that in the Middle Ages people lived on average 30 years, and at the moment 60-80 years.

In other words, life expectancy has at least doubled. Naturally, this matter was influenced by a combination of reasons, but medicine played a huge role. And, probably, 60-80 years is not the limit of an average life for a person.

It is possible that someday people will step over the 100-year mark. Scientists around the world are fighting for this.

Developments are constantly being carried out in the field of other sciences. From year to year, scientists around the world make small discoveries, slowly moving the world's population forward and improving life. Places untouched by man are being explored, first on our home planet. But work is happening all the time in space.

In the field of technology, robotics in particular is rushing forward. The creation of a flawless intelligent bot is underway. Once upon a time, bots were an element of science fiction and nothing more. However, already today some companies have real bots on staff that perform various functions and help improve work, save resources and do unsafe activities for humans.

I would also like to pay increased attention to electric computers, which 50 years ago took up a lot of space, were unhurried and required a whole team of employees to take care of them.

And at the moment, in fact, every person has such a machine; it is already called more simply and briefly - a computer. Now they are not only small-sized, but at the same time much faster than their predecessors, and anyone can figure it out.

With the advent of the computer, the world's population ushered in a new era, which is probably called “technological” or “information”.

Remembering about the computer, we should not forget about web development. This also had a big impact on the world's population. This is an inexhaustible source of information, which is now available to virtually every person. It connects people from different continents and instantly transmits information, something that would have been impossible to even dream about 100 years ago.

Here, you will certainly find something exciting, interesting and educational. You, even someday, may be one of the first to find out about a discovery that will not only change the world, but will change your consciousness.

How and with what to cut the pipe: exactly at 90°, at an angle of 45°

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.

How to cut a pipe straight

To ensure an even cut from a general-purpose tool, special devices should be used to fix the workpiece. These can be templates, vices or miter boxes. In addition, it is very important to correctly mark the future cut and, while working, make sure that the cutting line does not go to the side.

Making a template for cutting metal profiles

If you need to cut out a mass of pipes, make a template from a metal profile of a larger diameter on a cardboard sheet using the above method. The angle of inclination is checked with a protractor or a construction square - and then the two edges of the docked parts of the template are connected.

While working, on the part to be cut, where the template fits comfortably and is pressed tightly, the markings are applied with a sharply sharpened scriber while tracing the template outline. The part is cut in several passes with a gradual deepening of the groove.

Oblique incision at 45°

It is possible to cut the end of the pipe exactly at 45° without the use of complex devices. All you have to do is use your plumbing skills. You will need to do the following:

• Cut a piece of paper into a square shape.
• Fold diagonally. Learn the right isosceles triangle.
• Wrap the workpiece with a sheet so that the leg of the triangle is perpendicular to the axis, and the hypotenuse forms an upward spiral.
• Secure the sheet with tape.
• Fix the workpiece and cut along the oblique edge of the sheet. It will turn out at 45°.

Pipe bevel cutting

There is another popular method. The end of the workpiece is immersed in a container with liquid at the required angle. You need to cut along the border of the wet and dry areas.

If you need to cut not perpendicularly, then it is better to use an old carpentry tool - a miter box.

This is a U-shaped template, in the side walls of which slots have already been made at specified angles. The pipe is placed against the wall of the miter box farthest from the master and pressed there with a hand or a hand clamp. The hand saw blade is inserted into the appropriate grooves and sawed. If necessary, cut at a different angle, you can make additional cuts in the walls of the miter box.

For personal use

To cut iron pipes in the household, the following tools are used:

Manual pipe cutters. Allows you to cut round parts to obtain an even, right angle of cut using the cutting edges of the rollers. There are several varieties of products of this type, consisting of single rollers, as they are also called, in a row, attached to a chain. In everyday life, such devices are found quite rarely and are more suitable for professional work.

Bulgarian. It is a universal tool for cutting all iron parts with different angles; to perform the work, special metal discs are used, which are quickly ground down during use. Therefore, there is an option to accurately cut a curved line with a disk of small diameter.

How and with what to cut a pipe: exactly at 90°, at an angle of 45° - Website about

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.

How to cut a pipe at 45 degrees

When installing a pipeline, quite often you have to cut the pipe at an angle. Moreover, the angle should have exactly the degree that is needed for the structure.

If the angle is made incorrectly, it is impossible to produce exactly the dimensions of the pipeline that were supposed to be made. For example, the pipe will rotate 45 degrees during installation, therefore, you need to know how to cut the pipe at 45 degrees.

To do this we need marking tools, a grinder or a hacksaw.

Marking using a sheet of paper

One of the easiest ways is to mark the corner using a sheet of paper. We fold the square sheet strictly diagonally. We take the pipe and wrap it with a folded page so that the edges of the diagonals are opposite each other.

So, on the smaller side of the page we have an angle of 45 degrees. We take any marking tool and mark the location of the future pipe cut along the line of the page. To prevent the markings from being accidentally erased, you can use narrow tape.

This marking method is convenient for a long pipe of enormous diameter, and the cut point of which is somewhere in the middle.

Using a water container

What should we do if we are dealing with a small-diameter pipe, and we need to cut the pipe at an angle somewhere near the edge? A deep container filled with water will come to the rescue. Before you start working, you need to calculate the angle of inclination and make a mark on the container.

Then all we have to do is carefully lower the edge of the pipe into the water and tilt it towards the mark on the container. We remove the pipe, mark the line of contact with the water, and boldly cut along the markings. This method is optimal when marking a huge number of pipes.

A ready-made template from a container of water will speed up the process of our work.

Computer program to help

I would also like to consider the method of marking using a computer program. This is a super complicated method for those who are not used to working with a computer. It requires knowledge of a PC, programs for developments and drawings. We begin work by making a drawing indicating the size of the circle and the slope. We make a so-called virtual template.

After this, we print the image on a sheet of paper using a printer. The larger the diameter of the pipe, the more pages with markings there will be. Using scissors, we cut out all parts of the drawing and, using tape, glue them together. The finished template is applied to the pipe, and we make markings along the edge of the paper.

This marking method is considered one of the most correct. If your computer does not have such programs, you can use the Internet. It is possible to download a pattern for marking on the Internet. In addition, you need to print it on a printer and cut it out.

We wrap the finished pattern around the pipe and make markings.

If the pipe is profiled

But, for example, we have a profile pipe, not a round one. Manual marking of a profile pipe can lead to a huge error. The best way out of this situation would be to make a template from the same profile of a larger diameter.

Take a small piece of profile pipe and use a protractor to mark an angle of 45 degrees. We cut along the markings with a grinder and grind the edges so as not to get hurt by the burrs while working.

Then all we have to do is insert a profile of a smaller diameter into the template and, having made markings, cut it off.

In this article we looked at how to cut a pipe at 45 degrees. Using one of the methods listed above, mark and make a cut. For a more even cut, it is better to use a grinder. When cutting by welding, experience is required, otherwise the cuts will end up with unevenness. As a last resort, you can use a hacksaw. Currently, there are a large number of different devices for cutting pipes at an angle on sale, but purchasing them requires extra costs. It’s easier and cheaper to make a template for yourself once and use it as needed.

That is why the video will show you how to cut a pipe at an angle of 45 or 90 degrees using a computer program:
