How To Cut A Pipe At An Angle

Paper mold for pipe

One of the common ways to make a pattern for pipes with a round surface is a method for which you will need a lined sheet of paper, a ruler and a pencil. To obtain a paper pattern, proceed as follows:

  • Draw a circle on a piece of paper with the diameter of the pipe to be cut, break the circle into 16 equal segments, each time dividing large segments into two equal.

How To Cut A Pipe At An Angle

  • Measure the circumference by multiplying its diameter by the number Pi, equal to 3.14. Lay this size on both sides of the axis of the circle in equal segments, each of which is divided into 8 equal parts.
  • Draw from segments on a straight line vertical mowing line up and horizontal from the points set on the circle.
  • The points of their intersection are connected with a smooth line and, as a result, a template applied to the paper is obtained, which is cut out and glued to the trimmed surface. For trimming, it is better to use an angle grinder with a small diameter disc. the surface will be curved and when using a large disc, the error will increase.

DIY pipe miter box

Using the template is not very convenient. you have to cut along the mowing line, keeping the angle grinder suspended, which leads to large errors. If you have a welding machine, you can make a simple miter box. guides for the disc of an angle grinder, preventing it from going to the side.

For this, a previously made template is used, in the side of which a hole is drilled and a nut is welded. When working, a homemade miter box is put on the profile, a bolt is screwed into its nut and the device is pressed against the profile surface. an angle grinder with a disc for metal makes a cut, slightly pressing the disc to the side surface of the device. It is clear that with long-term work, the edges in the miter box are gradually grinded, and although the process occurs simultaneously on all edges, some errors will appear over time. Therefore, it is better to make the device from hard wear-resistant metal in order to increase its service life and get a more accurate tool.

How to cut thin walled pipes

Another type of pipes are thin-walled products. They are usually made from non-ferrous metals such as aluminum or copper. Cutting thin-walled pipes is more difficult, since there is a high probability of element deformation. In this case, you can use some kind of filler, such as sifted sand. As a tool, you can use an angle grinder, a hacksaw for metal or a special machine. It all depends on the specific situation.

Cutting metal pipes is a rather laborious, but do-it-yourself process. At the same time, work with round pipes does not fundamentally differ from cutting a profile pipe. The main thing to remember is that when performing work, you must follow safety rules.

Searching for records using a filter:

Final part

Do not think that an angle grinder with a cutting disc is a tool used exclusively for dismantling metal structures and does not require accuracy in work. Rather, the opposite is true. The angle grinder requires utmost concentration and accuracy in work. This is a rather traumatic tool, and therefore, when working with it, one should not forget not only about the correct marking, but also about the safety requirements.

Only accurate calculation and cutting will allow perfect alignment of pipes at an angle

HouseChief hopes that the methods described in today’s article will help novice craftsmen in performing various repairs. All questions that arose during the reading process can be asked in the comments below. In the same place, please describe your experience in cutting pipes, which may be useful to other readers.

Finally, we suggest watching a short that will tell you a little more about the methods of operation of the angle grinder.

Thermal applications

In addition to mechanical methods, thermal methods are often used, where welding or cutting machines work as a tool. For example, an autogenous gas torch or conventional welding machine (AC / DC).

With the help of such devices, thick-walled metal pipes are available for cutting. However, it is extremely difficult to obtain a perfectly smooth high-quality cut using the electric welding or gas autogen method.

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

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

Usually, after cutting by a thermal method, the products are subjected to additional processing. The cut line is leveled, the values ​​of the required angle are adjusted. This approach is economically unprofitable, since it is accompanied by additional costs for machining.

As a rule, a thermal cutting technique is used in the conditions of an industrial-production sphere. True, housing and communal services also often resort to this technique.

The thermal cut is also used for working with plastic material. There are devices. thermal guillotines. The sharp thin blade of such devices is heated to a high temperature, after which they perform a cut.

Thermal guillotines support bevel cutting and this is their advantage. However, for work with more rigid materials than PVC, wood, chipboard, these devices cannot be used.

To cut metal-plastic pipes, pipe cutters are needed that can evenly divide products with a multilayer structure into parts. The article recommended by us is devoted to their varieties and methods of application.

Conventional 90º perpendicular cutting

Some people think that you don’t even need to make any markings here, especially if you are holding a large angle grinder with a large cutting disc. However, after, when combining pipes cut without marking, problems may arise. In order to avoid them, you can use ordinary electrical tape or masking tape, which is glued around the pipe. At the same time, its edges at the starting and ending points should perfectly match. If everything is done correctly, after cutting, the two pipes will be combined, forming a perfectly flat line, without unnecessary gaps.

With the help of electrical tape, marking is quite simple.

Cutting at 45 degrees

But, if you still need to cut a round pipe made of steel or various types of plastics, then you will need a piece for cutting pipes at an angle, the shape of which is calculated manually or by machine. The task is greatly simplified if at an angle of forty-five degrees it is necessary to cut a metal profile of a square section.

For a quick cut, you can use an ordinary sheet of paper folded diagonally, with which you mark the surface for the future cut. Using folded paper, proceed as follows:

  • Carry out on the straight surface of the profile in the place where the cut is made, strictly perpendicular to the line;
  • Apply a diagonally folded sheet of paper to the side surface with the sharp end to the mowing line so that the top edge of the paper triangle is flush with the top side of the metal profile.
  • Draw the line with a pencil along the side of the sheet at an angle of 45 degrees, after which the paper corner is applied to the other side and outlined with a pencil (it is better to use a thin marker).

For sawing, you can use an angle grinder with a disc for metal, first drawing a thin line along the markings, and then gradually deepening it until the edges are completely separated.

Cutting at 90 degrees

To cut straight across a round pipeline or rectangular metal profile, use a sheet of plain paper. They wrap the workpiece in such a way that the edges of the paper sheet coincide, after which it is fixed on the part with tape or glue. an angle grinder is held near the edge of the paper sheet with a thin line, after which it is gradually deepened until it is completely cut.

Some tips for cutting pipes

Sometimes in the household it is required to cut to connect the pipeline at different angles or along the axis. The main tool for these works is a universal angle grinder and discs for metal.

Marking and cutting circular pipes

There are several ways to saw off the pipe or cut it into pieces. An angle grinder is the best tool for this task. But the biggest challenge remains the need to properly mark the cut line. They can be different, most often it is necessary to maintain either a right angle relative to the pipe axis, or 45 degrees. Techniques vary somewhat depending on which products need to be cut:

Pipes for water supply, gas and heating distribution;

Profile products for the assembly of 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;

Pipes made of steel, cast iron, thin-walled pipes of non-ferrous metals and soft alloys.

Both tasks can be solved quite simply, even without using a special pipe angle pattern.

Pipe Bevel Cutting Tool

The very process of marking the cut-off workpiece seems to be quite a simple matter. But it should be noted that the rounding made during the manual marking process will create an irreparable error after cutting, which will lead to inconsistencies and the formation of defective products. In order to exclude such defects, it is required to make a simple tool for clear marking of profile parts.

At the same time, cutting products at an angle of 450 is much easier. A regular cut from a U-shaped steel profile, made at an angle of 45 degrees, will become a reliable tool for accurate cutting of pipes. In this case, the size of the profile for the ruler must be selected so that it becomes possible to easily position the cut profile pipe in it.

Manual pipe cutting tool

To perform such a tool marking the correct angle, you must also have the following additional tool:

  • Protractor;
  • Scraper for metal;
  • Angle Grinder;
  • Cutting disc;
  • File.

Pipe bevel cutter

It is not difficult to make a measuring tool for cutting pipes. To do this, it is necessary to cut a segment 20-30 cm long from the profile blank. Using a goniometer, it marks an angle of 45 degrees at any end of the segment. Next, cut off the profile with the angle grinder. The resulting template needs to be tested for accuracy. In case of deviations, file the measuring tool.

Next, you need to cut the pipe clearly along the lines of the marking using an angle grinder. It is worth noting that at first the pipe is notched along the diagonal marks on both sides, then the straight, marked mowing lines are cut. These 45 degree pipe cutting templates will save you a lot of time and money.

Pattern for cutting pipes at an angle

When cutting round pipes at a 45 degree angle, the tool made for rectangular pipes is not quite suitable. For a more accurate. streamlined drawing of the mowing line of the cut at an angle, it is recommended to use a paper template, which is wound on the workpiece.

Patterns are developed in the modern world using computer programs.

Layout on paper is one of the simplest ways to accomplish a task. A square sheet is required. It folds flat diagonally. The resulting template for cutting pipes must be wrapped around the product so that the long side runs parallel to its section.

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

It is recommended to wrap the marking area with narrow tape so as not to accidentally erase it. This method is great for long, large pipes with a cut in the middle of the product.

This method of marking 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 must be highlighted. On it, the pipe is cut at an angle. This method is best for jobs that require multiple striping.

Cutting large diameter pipes

  • Angle Grinder. The use of an angle grinder is justified from the point of view of the availability of the tool and the relative cheapness of work. However, in this case, one should not count on high productivity, in addition, carrying out work in this way is fraught with considerable risk.
  • Roller machine. Such attachments are also often called pipe cutters. In fact, such a device is the same angle grinder, but more adapted for this type of work. The machine includes a special bed, where the cut-off element is fixed, as well as a cage with installed cut-off rollers, which do the direct work. It is important to understand that each machine must be purchased for specific tasks, that is, for the size of the pipes.
  • Gas cutting. This option is most often used when working with large diameters. Cutting is carried out using a high intensity flame, and the waste produced is blown out by the pressure of the gas. The method can be considered the most practical and effective.

Gas cutting is the fastest option in this case.

There are other options for accomplishing the task, such as the use of plasma, waterjet or laser cutting, but in private use they are practically not used.

How to cut a pipe at 45 degrees

One of the particular examples of this situation is the need to cut a metal pipe at an angle of 45 degrees. Such cutting of the material is often required when laying plumbing or heating systems. In this case, you have to deal with steel pipes. For these purposes, the usual 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 section are more often used. The main problem here is that in order for the elements to be connected to match, the cut must be as even as possible, which means that especially close attention should be paid to marking the material.

When 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 wrap the pipe with a 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.

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 section. In this case, you only have to use the measuring devices once. For marking, you will need to use a protractor or construction square.

When the need arises to crop at 90 degrees, things are even easier. In the case of cylindrical elements, the same sheet of paper with which the pipe is wrapped can be used as a template. It is important to ensure that the edge of the sheet is even and matches the entire circumference. After marking, the cut element is fixed and cut is made.

The process of cutting a pipe at 90 degrees is shown.

To mark the section [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 match exactly when applied, you get the perfect cutting line. If the tape or tape stuck tightly to the metal, you can walk right along the edge.

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

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 an angle grinder according to the markings, which are made either with a sheet of paper of the same A4 format, or use a regular school (drawing) isosceles square.

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

How to cut a cast iron pipe

The marking of the profile pipe differs from the round one. Manual execution can lead to significant errors. The best way to solve the problem is to create a cutting template from the same profile, but with a larger diameter.

A small piece of shaped pipe will be required. On it, using a protractor, mark an angle of 45 degrees. Now, using an angle grinder, you need to cut off a part of the workpiece along the marked mowing line. The cut edges must be sanded and defects removed. All that remains is to insert the original product into the bevel cutting template. Then you need to mark the mowing line for the cut of the larger profile. And already the pipe itself is cut along it.

You can cut a profile pipe in much the same way, but here it will be easier to use a square. The device is alternately applied to each side, for which the cut element will need to be rotated, and the markings are applied. Next, the pipe must be fixed immovably and you can start work.

If the pipe is made of cast iron, then in order to cut it evenly, you will have to apply certain knowledge. The fact is that this material is characterized by high fragility, which means that before cutting off such a pipe, you need to determine an algorithm of actions.

  • We mark it similarly to steel pipes.
  • At the place where the cut is made, you need to put a wooden beam as a support.
  • Next, you need to cut a few millimeters around the entire circumference.
  • After that, a chisel is inserted into the groove and a sharp and strong blow with a hammer must be applied.

As a result, it will split along the mowing line, forming a fairly flat cut point, which, if necessary, can be further processed.

Using a computer program

To implement this method of marking pipes for cutting, a computer with special programs is required. First, you need to draw up a drawing, which indicates the transverse dimensions of the product, as well as the planned cut angle. Need to get a virtual template.

Print it out on a printer. And here it should be understood that the larger the pipe diameter, the more sheets will be required for printing it. Then you need to carefully cut out the drawing details from all pages and glue it, it is best to use stationery tape for this. It remains to attach the template to the pipe and apply the markings.

How to cut along

Another frequently asked question is how to cut the angle grinder pipe straight lengthwise. Here the algorithm of actions will be approximately the same as for cross-cutting. It is important to pay attention to the marking. You can, for example, use a painter’s thread, which is usually used when marking walls. In this case, it is necessary to rigidly fix the pipe.

We cut the pipe at an angle of 90 degrees

Accurate sawing and cutting of pipes depends not only on well-executed markings. The material is also of great importance. metal of different thickness and hardness is cut with different efforts and side effects. To properly cut a cast iron pipe, it should not be sawed through to the full depth. Cast iron is a brittle metal, so several cuts are usually made, and then a specialist with one precise blow of a chisel beats off a piece on them.

To work with thin-walled pipes, you will have to very accurately adjust the position of the angle grinder. In this case, the master must choose the right [angle grinder for cutting metal]. In an industrial setting, special pipe cutters, gas cutters and welding machines can be used to perform the same tasks.

When working with gas pipes connected to the mains, it is important to observe safety measures. First turn off the gas supply valve, then make sure that there is nothing in the pipe. To do this, it is enough to open the burners of the stove and light the gas. when it runs out, the flame will go out.

Cutting metal pipes is a rather laborious, but do-it-yourself process. At the same time, work with round pipes does not fundamentally differ from cutting a profile pipe. The main thing to remember is that when performing work, you must follow safety rules.

How to cut a pipe straight at any angle

When doing repairs or laying new communications, you often have to look for an answer to the question: how to cut the pipe exactly? There are many simple methods that can achieve the desired result when cutting pipes from any material.

How to cut a pipe straight at a 90 degree angle

There are several nuances when cutting a pipe to the correct size. It is necessary to consider: the material of manufacture, the angle at which should be cut off. If the angle is right, then the marking is done as follows:

  • Measure the required length, apply with chalk or a marker line.
  • At the level of the mark, wrap the pipe with masking tape or a sheet of paper. It is necessary to ensure that the edges of the adhesive tape coincide with each other. This will ensure a smooth cut.
  • Cut off the pipe with an angle grinder. Exactly how the markings are made is possible only if the cut is made not at one time, but in several steps. After a small cut, it is necessary to turn the pipe by 20.40 degrees until a full turn occurs.

It is impractical to mark using a tape measure. When wrapped around the pipe, it breaks, making it impossible to draw a circle evenly.

How to mark out at a 45 degree angle

It is more difficult to make 45 degree markings. A small diameter pipe can be marked with water. If the piece is small, then this option will do. A pipe is lowered into a container with water at an angle of 45 degrees. Water leaves a mark on the surface that needs to be duplicated with a marker.

Using a paper template, you can mark any pipe diameter. It is done as follows:

  • A circle is drawn on graph paper equal to the diameter of the pipe.
  • The base of the circle will be the X-axis. On it you need to draw a segment equal to the length of the circle, so that the middle coincides with the axis of symmetry of the circle.
  • The resulting line must be divided into 16 equal segments.
  • the line of symmetry of the circle, which will be the Y-axis, is also divided into 8 segments.
  • From points that form segments, you need to make projections: from points on the X-axis, vertical, and from points on the Y-axis. Horizontal. The intersections of these projections must be connected with a smooth line.
  • The resulting figure must be cut with scissors.

The template is wrapped around the pipe and secured with masking tape.

It is difficult to cut the pipe straight at an angle. As a rule, a sander with a large diameter wheel is used, even for cutting thin pipes. A large circle is less distracting.

An interesting way to cut a plastic pipe

There are many tools for working with plastic pipes. There are special scissors that cut pipes with a diameter of up to 75 mm.

You can use a hacksaw for metal or just cut off an angle grinder. But all of these methods have disadvantages. Scissors cut at a 90 degree angle. But how to cut an even plastic pipe if a different angle is required or the large diameter does not allow them to be used? If you cut with a hacksaw, the slippery plastic surface prevents cutting according to the markings. You can make a device that is devoid of the listed disadvantages.

This tool combines pipe guides (miter box) and a nichrome thread cutter.

A nichrome thread is installed on the miter box at the desired angle. It is connected to the electrical network through a ballast or rheostat. This will make it possible to select the desired temperature. After heating the red-hot wire, the workpiece must be lowered into the miter box. This will allow you to cut the pipe straight like clockwork.

Straight cut

It is possible to make a straight cut at an angle of 90º only after marking. Use a piece of paper or masking tape. The latter is preferable, because it is attached directly to the surface and does not move.

The sequence of actions looks like this:

  • Use a tape measure to measure a segment of the desired length, mark this place with a dash marker.
  • Next, along the received mark around the circumference of the pipe, adhesive tape is glued. The more evenly you stick the adhesive tape, the better. it is optimal so that the wide edges meet as accurately as possible. This will allow you to accurately cut the pipe along the mark.
  • The next step is to fix the pipe in a vise or press it against a flat plane so that it does not move during operation, and an even seam is obtained. Note that one end of the pipe must be left in a free position so that the disc is not pinched by the walls during cutting. Cutting starts from top to bottom.
  • The last thing to watch out for. How to cut a pipe straight angle grinder. To do this, guide the disc as precisely as possible along the edge of the adhesive tape.

In cases where pipe products with large sections are cut, the work must be performed in small sectors. To do this, the pipe will have to be constantly rotated around the axis at the end of the next cut.

Tools for home and semi-professional use

For the arrangement of water supply or sewage systems, heating and ventilation circuits in home construction or in the provision of construction services, tools from this category are often used.

Some of the most common devices include:

  • Cutters with pruning shears. Such a tool is used for cutting polymer pipes, the cross section of which does not exceed 75 mm. The gear mechanism of the device allows to apply the necessary force for work. The design of such a cutter provides for a special shelf on which the pipe is laid, which ensures the evenness of the cut strictly at 90º. for such tools can be very different, it all depends on their quality, dimensions, capabilities, manufacturer and other factors.
  • Disc type pipe cutter. In such a device, the pipe is cut by a special disc, which is made of durable material and has sharpened edges. With the help of a lever, the cutting disc is pressed against the surface of the pipe and is guided along its section. Read also: “How to choose a steel pipe cutter and how to use it”.

The best solution for such a tool would be for cutting PVC pipes used in the assembly of indoor and outdoor sewerage systems. At the same time, metal-plastic pipes cannot be processed with such a pipe cutter, since the material is deformed under load.

  • Guillotine knife. The principle of its operation is probably familiar to every educated person. In the upper part of the structure there is a blade that goes down along special grooves and makes an even, clear cut. For convenience, you can get a device with an electric drive. With such a device it is easy and convenient to cut a large number of pipes. However, at points of sale you can also find tools with a screw mechanism.
  • Hacksaw for metal. Such a seemingly simple tool can be successfully used to cut pipes from any material. The main thing is not to overdo it during work, so that the saw blade does not break from excessive efforts.
  • Angle grinder, or, in other words, angle grinder. The process of how to cut a pipe straight from an angle grinder is not particularly difficult. To work, disks of the required diameter are installed on it and cutting is performed. over, processing can be carried out on pipes with different sections and any materials, be it polymers or metal.
  • Electric jigsaw. Although this tool is also widely used in construction, it is not very suitable for cutting pipes, since it is rather difficult for them to cut the pipe exactly.

Consequently, there are many convenient tools that are easy to operate, so you shouldn’t look for difficult ways when everything can be done quickly and easily.

In addition to hand tools for household work and small construction, there is also professional equipment that is used in industry and for laying large main water lines.

Pipe cutting technique

Immediately, we note those cases when work should be done to install the heating system.

In this situation, you will need to purchase a special pruner. it will allow you to cut the pipes exactly without deforming them, and its cost is low. But simpler work can be performed with simple improvised means.

How to cut a pipe straight. cutting tools and methods

In everyday life, we are constantly faced with the need to lay pipelines from various materials, whether it is water supply, sewerage, heating, installation of cable channels, or even the construction of frame structures in a house or in the country. This article will tell you how to cut a pipe exactly for certain purposes, if you do all the work yourself, that is, it provides detailed instructions for all technological operations. Also, let’s talk about the variety of tools for hobbyist or industrial use.

What tools are used to cut pipes

At first glance, it might seem that pipe cutting is a fairly straightforward process that is not worth a separate 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 otherwise, since there will be no further welding or joining of the ends. And it’s quite another matter when you need to make an absolutely accurate cut. Note that if you need to cut oblique ends with an exact angle, you should consult with experienced craftsmen.

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

Industrial equipment

In professional construction and when working with large engineering objects, the question of how to cut a large diameter pipe evenly is solved by using special equipment. Quite often, these are stationary units with a certain set of qualities.

Among the most interesting and functional devices are the following:

  • Lathe of various modifications. With the help of such a machine, you can evenly cut a profile pipe for both a regular water supply system and especially durable products through which liquids with an aggressive environment will pass.

The maximum cross section of the pipe to be machined will vary depending on the distance between the support heads and the diameter of the holes in the spindle. These units can be called universal, because they can cut, chamfer, and also carry out a number of other actions, often in automatic mode.

  • Belt-type cutting machines. Such units are used for cutting pipes of water supply or sewage mains, previously laid in trenches or carried out in a building.

The cutting band can cut pipes, even those that have been heavily deformed. Additionally, such a cutter can chamfer the desired shape.

  • Cutting machines with circular knives. Equipment of this type is capable of cutting pipes made of any metals, including non-ferrous ones. In addition, they have no restrictions on the shape of the product. they can be both round and profiled, with a rather large section.

As a rule, such units are installed on conveyor belts and are additionally equipped with a machine that, after cutting, collects and packs a given number of pipe sections, which will then be sent to customers.

  • Hand-type disc cutters. They are used mainly in cases where cutting a large number of pipes is required directly at the places of their laying. On such machines there is a special clamp that tightly grips the pipe during cutting, preventing it from displacement and deformation. Due to this quality, such equipment can be successfully applied to both metal-plastic and copper or steel pipes.

A number of disc-type cutting machines have built-in orbital welding and a rotation system, which allow cutting and subsequent joining of parts with one mechanism. Such a device can be very useful if you need to perform a very large amount of work on cutting, welding or joining pipes without having stationary equipment.

Often, pipes can be cut evenly with the help of simple improvised tools that every owner can find.

Bevel cutting

In this case, we will show you how to cut a pipe at a 45º angle. The markup will be needed in this case too (more details: “How to cut a pipe at an angle. marking options for round and profile pipes”).

To apply it, you need a square sheet of paper, which must be folded diagonally. The resulting triangle is wrapped around the pipe and fixed. This will give an angle of 45º.

You can, of course, try to lower the pipes at the desired slope into the water, then the border of the wet surface will serve as a markup. However, it is best to use a special device for corner cutting. a miter box.

In shape, the miter box looks like an inverted letter “P”. Pre-made holes with different angles have already been made in its opposite walls. It is enough just to place the pipe inside the fixture and cut it by running a hacksaw along the selected grooves.


Thus, it is quite simple to make an even pipe cut from any material on your own. In this matter, there are only a few tricks that will allow you to quickly and efficiently carry out all the work and build yourself the desired object for a farm or summer cottage. Note also that it is better to check the measurements several times before starting cutting, because you can accidentally make a mistake and spoil the material, while incurring additional financial losses.

Cutting pipes at an angle: advantages and disadvantages of different ways an example of work

Pipes are a widespread building material. They are used in the installation of various systems. During the installation process, situations occur when the pipes must be joined at an angle. The technology for the production of such works is not standard, but you need to know about it.

To create complex joint configurations, bevel cutting of pipes is required. We will tell you how such operations are performed and what cutting methods exist.

Miter box for cutting pipes

There is a simple tool that is often used in everyday life, mainly for working with wood. It is called. miter box. So, the same device is suitable for cutting pipes, and at different angles.

The miter box is on sale, but if you wish, you can always make it yourself and adjust the structure to the required pipe diameter:

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

In this way, a template for cutting at an angle of 45º is made. But with the help of a protractor, you can mark almost any angle and make cuts for a pipe cut for a specific angle.

The advantage of the miter box is that the tool is suitable for repeated use. Working with the tool is permissible to such a degree of wear on the walls of the slots, as long as they can provide high cutting accuracy. It is recommended to make the walls of the tool from a material of higher strength than wood.

The advantages of the method are obvious. simplicity, ease of making a tool (miter box), efficiency, versatility. The disadvantages of working with such a tooling option are the need to adjust the dimensions of the miter box to the pipe diameter, provided that an accurate cut is made. That is, for each pipe you have to make your own instrument.

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

Programs for calculating cutting angles

Curve cutting technology allows obtaining different cutting angles. But to form a piece at angles other than 45º, it will already be necessary to perform mathematical calculations and, according to the calculated data, cut out a template from paper or similar materials.

True, there are computer programs designed to save the foreman from making calculations. Patterns for cutting pipes such programs are printed on a printer.

A simple calculation program created on the basis of the MS Excel application allows you to calculate and create a pattern for almost any values ​​of pipe diameters and required cutting angles.

All the user needs to do is enter the corresponding values ​​into the “Outside diameter” and “Cut angle” cells. According to these parameters, a pattern will be formed that can be sent to print.

Simple tooling for cutting

Round and rectangular metal products with fairly thick walls are conveniently cut at an angle using simple electromechanical equipment.

The cutting element of such a tool is a cutting disc or a circular saw attached to the shaft of an electric motor. In turn, the electric motor with a cutter is part of the entire equipment, which includes a work table, a pendulum support, a clamp.

To install the pipe at the desired angle with its subsequent fastening, an ordinary clamp and two metal corners are used. One corner (short) is attached to the base of the swing mechanism. the pendulum. The second corner (long) is in a free state.

Pipe laying and cutting procedure:

  • The swivel mechanism sets the required cutting angle (for example, using a ruler and protractor).
  • The found position is fixed with clamping screws.
  • A pipe is laid between the short and long corners and pressed with a clamp screw.
  • Voltage is applied to the electric motor.
  • Applying a slight pressure to the cutter blade, the pipe is cut in the right place.

The advantages of this technique are fast work, accurate cut, 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 process of cutting with equipment is carried out stationary at a distance from the installation site, which is not always acceptable.

If you are going to make a copper pipeline at home, then you will need special pipe cutters, with the rules for the selection of which we advise you to familiarize yourself.

Techniques for cutting pipes at an angle

Considering the methods of work. cutting straight or at an angle. one should take into account the different material of the products being processed. So, sleeves made of polypropylene or thin copper are easier and easier to cut than thick-walled steel pipes.

Small diameter plastic products are cut at the desired angle using special scissors. At the same time, you can control the angle with an ordinary protractor. Plastic pipes are also cut with a conventional hacksaw with a fine-toothed blade.

The most frequent need for installation is cutting water, sewer and ventilation pipes at an angle of 45º.

Find out which tools can be used to cut at different angles.

Paper mold for pipe

To perform a relatively accurate cut, you can apply a simple technique, where a regular sheet of paper acts as a kind of pattern. For example, A4 printer paper is well suited for creating a pattern.

Previously, the sheet is laid out under a square using a ruler. The diagonal size of the square must be equal to the circumference of the pipe to be cut. The excess parts of the sheet are cut off.

Then the following steps:

  • Bend the sheet diagonally by aligning opposite corners.
  • Turn the resulting triangle so that the line of the hypotenuse is perpendicular to the pipe axis.
  • In this position, wrap the tubular surface with paper, aligning the extreme points of the hypotenuse together.
  • Use a marker to mark the cut along the mowing line of any of the legs of the triangle.
  • Cut the pipe to the intended mowing line.

This method is quite convenient to mark and cut pipes at an angle of 45º in the range of diameters from 32 to 63 mm. For better markup convenience, it is recommended to use thick, but soft paper. Paronite and similar materials can also be used.

How to correctly choose a pipe cutter for plastic pipes and how to use it in practice is described in detail in our article.

Competently made patterns for true shape cutting of pipes allow you to make cuts with extremely high accuracy. In this case, the gap between the prepared workpieces is still not excluded. In the connection of metal pipes, it is “closed” with a weld; when connecting plastic parts, a specialized cord for soldering is used.

The nuances of working with a rectangular section

To perform cutting of products of rectangular cross-section, it is recommended to prepare template cuts of the corners in advance. They are easy to make from a metal corner, having previously marked with the same protractor.

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

Precision cutting machines

Among the branded devices that could be used in everyday life to perform an angle cut, you can pay attention to the technique of Italian production.

The Mini Cut band saw from the MASS company is a small-sized device with a hand clamp, for working not only with pipes, but also with corners, rods, and profile elements.

The machine supports setting the cutting angle from 0 to 45º. The procedure is carried out using a tape belt with a speed of 45 reciprocating movements per minute. The device is equipped with a 370 W electric motor, which is powered by a household network. Maximum permissible diameter of the cut round pipe. 65 mm.

Numerous machines with electromechanical and electric drive have been developed on an industrial scale for pipe cutting. Technically sophisticated devices allow high precision thermal, oxygen and plasma cutting:
