Pipes are a widespread building material. They are used in the installation of various systems. A common thing during the installation process is the situation when the pipes must be joined at an angle. However, the technology for the production of such works is not quite ordinary. To create such a joint configuration, pipe cutting at an angle is required. Consider how such operations are performed and what cutting methods exist.

Considering the methods of work - cutting directly or at an angle - it is necessary to take into account the different material of the products subjected to processing. So, 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 right angle using special scissors. At the same time, you can control the angle with an ordinary protractor.

Cutting pipes in the process of working with these mounting elements is very common. A popular tool for such cases is the so-called grinder. With this tool, cut straight and at an angle

The most common installation need is cutting water pipes or other pipes at an angle of 45º. We will find out which devices can be used for cutting from this and other angles.

Paper pattern for pipe

For the execution of a relatively accurate cut, you can apply a simple technique, where an ordinary sheet of paper acts as a kind of pattern. For example, it is suitable for creating patterns of A4 printer paper. Previously, the sheet is marked out under a square using a ruler. The diagonal size of the square should be equal to the circumference of the pipe to be cut. Excess parts of the sheet are cut off.

The simplest way to get a marking line on a pipe to produce a cut at an angle of 45 degrees. A plain sheet of paper is used that is applied to the pipe body in the cut area.

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 pipe surface with paper, aligning the extreme points of the hypotenuse together.
4. Mark with a marker the cut mark along the line of any of the legs of the triangle.
5. Trim the pipe along the intended line.

In this way, it is quite convenient to mark and cut pipes at an angle of 45º in the range of diameters from 32 to 63 mm. For greater convenience, it is recommended that you take thick but soft paper. You can also use paronite and similar materials.

Programs for calculating cutting angles

Cutting technology for patterns allows you to get different cutting angles. But for the formation of a pattern at angles other than 45º, it will already be necessary to carry out mathematical calculations and, according to the calculated data, cut out the template from paper or similar materials. True, there are computer programs designed to save the wizard from the production of calculations. Patterns for pipe cutting such programs are printed on a printer.

This is what the window of a computer program that calculates the cut angle for a circular section looks like. Based on the calculation results, a pattern is drawn that can be printed with a printer. A pattern is cut out on a pattern

A simple calculation program, created on the basis of MS Excel, allows you to calculate and compose a pattern for almost any value of pipe diameters and the required cutting angles. All that the user needs to do is enter the corresponding values \u200b\u200bin the “Outer Diameter” and “Cutting Angle” cells. According to these parameters, a pattern will be formed that can be sent for printing.

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

Pipe cutting miter box

There is a simple tool, often used in everyday life, mainly for working with wood. It is called - a miter box. So, this same device is suitable for cutting pipes, and at different angles. The miter box is on sale, but if you want, you can always do it yourself and adjust the design to the desired pipe diameter:

1. Take a wooden board with a width equal to the diameter of the pipe, 400-500 mm long.
2. Take two more boards of the same size, but in width increased by the thickness of the first board.
3. From three boards to assemble the design 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, the two sides of which pass along the inner borders of the side boards.
5. Divide the rectangle with diagonals and along the lines obtained on the upper faces of the side boards, make cuts down to the base.

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 under the pipe cut for a specific angle. The advantage of the miter box - the tool is suitable for repeated use. Work with the tool is permissible to such a degree of wear of the walls of the slots, while they can provide high precision cutting. It is recommended that the tool walls be made of a material of higher strength than wood.

This looks like a possible design of the miter box - a device thanks to which it is also possible to cut pipes at different angles. However, the miter box, as a rule, is conveniently used for cutting pipes of small diameters and with a small wall thickness

The advantages of the method are obvious - simplicity, ease of manufacture of the tool (miter box), efficiency, versatility. The disadvantages of working with such a snap option are the need to adjust the size 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 tool.

Also, with the help of a miter box, you can cut a pipe only with a hacksaw for metal or a secateurs (for plastic products). For working with thick-walled metal pipes under a cut grinder, this tool will not work.

Simple cutting equipment

Metal products of round and rectangular shapes, having sufficiently thick walls, are conveniently cut at an angle using straightforward electromechanical equipment. The cutting element of such a tool is a cutting disc or circular saw mounted on an electric motor shaft. In turn, the electric motor with a torch is part of the entire equipment, which includes the desktop, pendulum support, clamp.

Electromechanical device for cutting pipe elements, including at different angles. A disk cutter and a simple mechanical system for fixing the pipe in different positions are used

To install the pipe at the desired angle and then fasten it, 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:

1. The rotary mechanism sets the desired cutting angle (for example, using a ruler and protractor).
2. The found position is fixed by clamping screws.
3. Between the short and long corners, a pipe is laid and pressed against the clamp screw.
4. A voltage is applied to the electric motor.
5. Applying a slight pressure force to the torch disc, 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 on use in domestic conditions, increased noise, work with pipes of only small and medium diameters. In addition, the snap cutting process is carried out stationary at a distance from the installation site, which is not always acceptable.

The nuances of working with a rectangular section

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

Cutting rectangular pipes (profile elements) at the required angles is usually performed according to the templates. Such patterns are made of metal corners of various sizes.

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

Precision Cutting Machines

Among the branded devices that could be used in everyday life for cutting at an angle, you can pay attention to Italian-made technology. The MASS Mini Cut Band Saw is a small-sized device with a manual clamp, for working not only with pipes, but also with corners, rods, and profile elements.

Convenient and productive apparatus for cutting pipes of small and medium diameters. The cutter is made on the basis of a steel strip that can be installed to cut at an angle

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

Industrial models (for example, BSM)

There are special industrial machines for precise angle cutting operations. A good example: devices manufactured under the brand name "BSM". The machine manufacturer is the German company Rexinger. True, the BSM series machines are designed exclusively for working with polypropylene pipes of sufficiently large diameters. Processing of products like PP, PVC, PE, PVDF is supported.

Industrial machine for cutting pipe products from polymers. Designed to work with products of large diameters, but has equipment for processing pipes from 50 mm. The car provides a cut in a wide range of angles

The cutting tool of the machine is a band saw, due to which the cut is performed at angles from 0 to 67.5º. The precision of the process is provided by a laser cutting recognition. Despite the configuration of the device for products with large diameters, you can use a special table with which pipes of small diameters (50 - 200 mm) can also be successfully cut. A wide range of BSM devices is available.

The use of thermal methods

In addition to mechanical methods, thermal methods are often used, where welding or cutting machines work as tools. For example, an autogenous gas cutter or a conventional welding machine (direct / alternating current). Using such cutting machines, thick-walled metal pipes are available. However, it is extremely difficult to obtain a perfectly even high-quality cut using the electric welding or gas autogen method.

Electric and autogenous cutting technology is ubiquitous. The technique does not provide high precision cutting, but when installing pipes this factor is often not determining

Usually, after thermal cutting, the products are subjected to additional processing. The cut line is aligned, the values \u200b\u200bof the required angle are adjusted. This approach is economically disadvantageous, as it is accompanied by additional costs for machining. As a rule, the thermal cutting technique is applied in the conditions of the industrial-production sphere. True, utilities also often resort to such a technique.

Thermal cutting 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, and then perform a cut.

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

Video: how to cut a pipe

The video shows the calculations and shows a workshop on cutting pipes at angles of 45 and 90:

For each individual installation case, you can choose the most convenient and less expensive method of cutting. The specific choice depends on the material of the pipe, its diameter, 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, turning to a complex calculation procedure, it is possible to cut at non-standard angles with high accuracy.

When installing the pipeline, it is often required to cut the pipe at a certain angle. When performing this task accuracy plays a big role. There are several easy ways to cut the pipe at an angle.

An incorrect section of the pipe will lead to the impossibility of mounting the structure of the form that was originally conceived. For example, if you plan to rotate the system by 45 degrees, then you need 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 for metal).

Marking the corner with a paper sheet

Paper sheet marking is one of the easiest ways to complete a task. A square sheet is needed. 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. It remains to mark the cut line with a construction pencil or marker on a sheet of paper.

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

This marking method is suitable for pipes of small diameter, which are planned to be cut at a certain angle near the edge. First you need to prepare a deep container with water. It indicates the planned angle of inclination. Now you need to carefully immerse the end of the product in the liquid, tilt it to 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 distinguished. On it, the pipe is cut at an angle. This method is best suited for jobs where multiple markings are required.

Using a program for a computer

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

Print it on a printer. And here it is worthwhile to understand that the larger the diameter of the pipe, the more sheets will be required to print it. Then you need to carefully cut out the details of the drawing 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 mark.

This method of solving the problem is highly accurate. All necessary programs can be downloaded on the Internet, they are free to download and use. There you can also find a piece for cutting pipes at an angle. It remains just to print and cut it. To perform the marking, the piece simply wraps around the pipe.

How to cut a profile pipe at an angle

The marking of the profile pipe is different from the round. Its manual execution can lead to a significant error. The best way to solve the problem is to create a template for cutting from the same profile, but larger in diameter.

A small length of profile pipe is required. On it using a protractor, mark an angle of 45 degrees. Now, with the help of a grinder, it is necessary to cut off part of the workpiece in a marked line. The edges of the cut must be sanded, to eliminate defects. It remains to simply insert the original product into the template for cutting pipes at an angle. Then you need to mark on the cut line of a larger profile. And already the pipe itself is cut along it.

The text describes how to cut a pipe at an angle of 45 degrees. When the marking is already completed, it is recommended to use a grinder. With its help, it will turn out to make an even cut. It can be replaced with a hacksaw. It’s also possible to cut the product by welding, but you need experience with the tool, otherwise there will be bumps.

Now in construction stores you can find special tools for cutting pipes. But it’s easier and cheaper to make a template yourself.

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

45 degree cutting

One particular example 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 communications 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 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 coincide, the cut must be as even as possible, which means that special attention should be paid to the marking of the material.

In the case 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 closer to the end of the pipe, is perpendicular to its central axis. Next, a number of dashed lines are drawn with the help of the marking material, and after the marking is completed around the entire circumference, the template can be removed.

If cutting a profile pipe is ahead, then it is advisable to produce a special template from the same pipe, but with a larger cross section. At the same time, it is necessary to use measuring devices only once. For marking, you will need to use a protractor or a building square. After sawing the template, the pipes to be cut can simply be inserted into it and marked out. This approach will significantly save time and cutting a profile pipe at 45 degrees will be convenient.

As for what to use during the work, here it is worth choosing the most suitable and familiar. It can be simple, and a Bulgarian with a cutting disc installed.

90 degree cutting

When the need arises to crop to 90 degrees, the situation is even simpler. 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 flat and matches the entire circumference. After marking, the cut element is fixed and cut.

The video shows the process of cutting pipes at 90 degrees.

How to cut a profile pipe evenly

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

Any suitable tool may be used for sawing. If you have to cut pipes a lot, then it is advisable to make full-fledged templates from scraps. In this case, the measuring and marking work will have to be done only once.

Large diameter pipe cutting

When it is necessary to cut a pipe of large diameter, a number of special devices and tools can be used. This may be necessary if, for example, it is necessary to repair the pipeline.

• Bulgarian.   The use of a grinder is justified in terms of the availability of the tool and the comparative cheapness of the work. However, one should not count on greater productivity in this case, in addition, carrying out work in this way is fraught with considerable risk.
• Roller machine. Such devices are also often called pipe cutters. In fact, such a device is the same 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 clip with installed cutting rollers, which perform direct work. It is important to understand that each machine should 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. The cutting is carried out due to the influence of a high intensity flame, and the waste produced during this process is blown out by gas pressure. The method can be considered the most practical and effective.

There are other options for the implementation of 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 cast iron pipe

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 you cut such a pipe you need to determine the algorithm of action.

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

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

How to cut along

Another frequently asked question is how to evenly cut the pipe along the grinder along. Here the algorithm of actions will be approximately the same as with transverse cutting. It is important to pay attention to marking. You can, for example, use a masking thread, which is usually used when marking walls. In this case, it is necessary to firmly fix the pipe. The sawing process itself must be done carefully and without rushing, since when sawing long elements there is a high probability of the cutting disc slipping off the marking line.

How to cut thin-walled pipes

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

Cutting metal pipes is a rather time-consuming, but quite 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 it is necessary to comply with safety regulations.

In various works, home craftsmen sometimes face the need to mark and cut pipes at forty-five degrees.

There are a large number of industrial devices for cutting pipes at different angles, but the cost of such devices is quite high. The article will discuss how to mark pipes under a cut of 45 degrees at home, without the use of expensive devices.

Marking and cutting of a profile pipe

The marking of a profile pipe at first glance seems quite simple. However, rounded corners with manual marking will give a serious error. For this reason, it will be more convenient to make the simplest device for marking a profile pipe. Metal pipe cutting at 45 °when using this device is simplified at times.

Tool for cutting pipes at forty-five degrees   represents a segment of a p-shaped steel profile cut at an angle of 45 degrees. The dimensions of the profile are selected in such a way that the marked pipe is freely placed in it. To make this device you will need the following tools:

• Goniometer;
• Scriber for metal;
• Angle grinder (grinder);
• Cutting disc;
• File.

Such a device for cutting pipes is made quite simply. It is convenient to use for cutting a large number of pipes, for example, for welding a frame.

A blank of about 20-30 centimeters in length is cut from the profile. Using a protractor, an angle of 45 degrees is marked on one of the ends of the segment. After marking, with the help of a grinder, the profile is cut. On the resulting template, you need to check the accuracy of the angle. If necessary, the template is finalized with a file.

Cutting a pipe at forty-five degrees using this template is greatly simplified. The pipe blank is put into the template and marked with a scriber. When marking, it is necessary to check the length of the workpiece. After that, the pipe is cut according to the marked marks with a grinder.

The pipe is cut along the diagonal lines on both sides, after which the straight marking lines are cut. This device for cutting pipes at an angle significantly saves time and money.

Pipe marking and cutting at an angle of circular cross section

When it is necessary to cut a round pipe at an angle of 45 degrees, the device discussed above may not be suitable. Pipe cutting at 45 degrees in this case is done on paper patterns wrapped around the workpiece. You can download the layout template.

Such patterns are printed from special computer programs. Also on the Internet you can find and print ready-made patterns for the most common pipe sizes. Whatever method of cutting pipes is chosen, it is necessary to monitor the accuracy of marking. The accuracy of the cut depends on this.

Thank you for adding this article to:

This tool is a profile in the form of an inverted letter P. On its sides there are slots for sawing at an angle of 45, 60 and 90 degrees. More complex corner templates or miter boxes have devices for setting different cutting angles.

For an inexperienced master, the best option is to purchase a finished miter box in a hardware store. At home, it can be made of three planed boards or plywood.

The tool can be assembled by fastening together pre-prepared parts. The box of the corner template must be fastened with wood glue or screws. The side walls of the miter box must be strictly parallel to one another. The horizontal beam should create a strict perpendicular with lateral.

Step 3: we plan slots at different angles to saw the laminate, platbands, etc.

The application of slots will affect the accuracy of the work performed in the future. Therefore, this process must be approached with particular painstakingness. It is desirable to produce cuts with the help of the same hacksaw with which the work will be performed.

Step 4: preparing the material to be sawed at an angle of 45 degrees

It is necessary to fix the finished corner template on the desktop using a clamp. Next, the marking of the future cut should be applied to the workpiece. Next, you need to combine the workpiece with a slot of 45 degrees inside the miter box and press firmly.

The hacksaw must be inserted into the corresponding grooves of the corner template and saw the workpiece. Grooves will limit the movement of the saw and the cut will be carried out in the right direction.

Subtleties of work with a miter box and various materials

When sawing such elements as the baseboard, it is not always worth doing a cut of 90 degrees. After all, the walls in the room can be uneven. Before sawing the baseboard, you need to adjust the angle of cut.

Thus, the article described and characterized the process of sawing wood materials with the help of a miter box.

When installing the pipeline, it is often required to cut the pipe at a certain angle. When performing this task accuracy plays a big role. There are several easy ways to cut the pipe at an angle.

An incorrect section of the pipe will lead to the impossibility of mounting the structure of the form that was originally conceived. For example, if you plan to rotate the system by 45 degrees, then you need 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 for metal).

Marking the corner with a paper sheet

Paper sheet marking is one of the easiest ways to complete a task. A square sheet is needed. 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. It remains to mark the cut line with a construction pencil or marker on a sheet of paper.

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

This marking method is suitable for pipes of small diameter, which are planned to be cut at a certain angle near the edge. First you need to prepare a deep container with water. It indicates the planned angle of inclination. Now you need to carefully immerse the end of the product in the liquid, tilt it to 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 distinguished. On it, the pipe is cut at an angle. This method is best suited for jobs where multiple markings are required.

There you can also find a piece for cutting pipes at an angle. It remains just to print and cut it. To perform the marking, the piece simply wraps around the pipe.

How to cut a profile pipe at an angle

The marking of the profile pipe is different from the round. Its manual execution can lead to a significant error. The best way to solve the problem is to create a template for cutting from the same profile, but larger in diameter.

A small length of profile pipe is required. On it using a protractor, mark an angle of 45 degrees. Now, with the help of a grinder, it is necessary to cut off part of the workpiece in a marked line. The edges of the cut must be sanded, to eliminate defects. It remains to simply insert the original product into the template for cutting pipes at an angle. Then you need to mark on the cut line of a larger profile. And already the pipe itself is cut along it.

The text describes how to cut a pipe at an angle of 45 degrees. When the marking is already completed, it is recommended to use a grinder. With its help, it will turn out to make an even cut. It can be replaced with a hacksaw. It’s also possible to cut the product by welding, but you need experience with the tool, otherwise there will be bumps. See also: "How to cut a pipe evenly - tools and methods of cutting."

Now in construction stores you can find special tools for cutting pipes. But it’s easier and cheaper to make a template yourself.

When carrying out installation work on gas or water mains, it is often necessary to change the direction of the line, while the pipeline is cut off and then welded at the right angle. Most often, the direction changes by 90 degrees, while the question arises - how to cut a pipe at 45 degrees in order to accurately connect the joints when welding.

To cope with the problem at the edges of the cut edge of 45 or 90 degrees, you can use the appropriate knowledge and techniques that will help to save not only time, but also materials during the work. At other turning angles, it is impossible to solve the problem with a ruler and a sheet of paper - you will have to call computer equipment for help.

Fig. 1 How to cut a pipe at an angle of 45 degrees

45 degree cutting

Usually, in order to rotate the pipe by 45 degrees, fittings are used, bends with an angle of rotation of 45 degrees, made of the same material as the pipes themselves, if the pipes are steel, then the turns are welded from steel. For HDPE pipes, there are electric-welded or cast bends at 45 degrees (note that it is almost impossible to find compression fittings with such an angle of rotation in Russia).

But, if you still need to cut off a pipe of circular cross section from steel or various types of plastics, then for this 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 the metal profile of a square section.

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

• carried out on a straight surface of the profile in the place where the cut is made, strictly perpendicular to the line;
• apply a folded diagonal sheet of paper to the side surface with a sharp end to the line so that the upper edge of the paper triangle is flush with the upper side of the metal profile.

Fig. 2 Homemade pipe cutting template at 45 degrees

• draw a line with a pencil on the side of the sheet at an angle of 45 degrees, after which the paper corner is applied to the other side and circle it with a pencil (it is better to use a thin marker).

For sawing, you can use a grinder with a metal disc, drawing at the beginning a thin line along the marking, and then gradually deepening it until the edges are completely separated.

When working with a grinder, the following factor must be taken into account - when the edges are completely cut off, the disk may be damaged by an acute angle, which will lead to its failure, and if there is no protection on the grinder, even to injury to the worker. Therefore, it is advisable not to trim the corner edges to the end, but to leave a narrow groove and then break off, subsequently grinding the protrusion.

Making a template for trimming a metal profile

If you need to cut a large number of pipes, you can make a template from a metal profile of a larger diameter on a paper sheet in the above way. The angle of inclination is checked by a protractor or building angle - in this case, the two edges of the trimmed parts of the template are connected.

When working on the part to be cut, the template is put on in the right place and pressed tightly, the marking is applied with a sharpened scriber when the template path is drawn. The part is cut in several passes with a gradual deepening of the groove.

Fig. 3 Cutting a metal profile with a miter box

Do-it-yourself miter box for pipe cutting

Using the template is not very convenient - you have to make a cut along the line, keeping the grinder on weight, which leads to large errors. In the presence of a welding machine, you can make a simple miter box - guides for the disc grinders, preventing it from going sideways.

To do this, use the previously made template, 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 to the profile surface. A grinder with a disk for metal is cut, slightly pressing the disk against the side surface of the device. It is clear that with prolonged operation, the edges in the miter box gradually grind, and although the process occurs simultaneously on all edges, some errors will appear over time. Therefore, it is better to make the device out of hard wear-resistant metal in order to increase its service life and obtain a more accurate tool.

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

Pipe cutting at an angle of 45 and 90 degrees

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

Some masters try to mark the place of the cut with a tape measure, but we warn that the result is most likely to turn out negative. And for a positive result, consider the following recommendation of professionals.

Take a sheet of paper or cardboard, preferably A4, fold it diagonally and wrap it around the pipe where you plan to cut it straight. The edges of the paper should absolutely coincide with each other. And the side of the paper that was closer to the end of the pipe was perpendicular to the axis. Then, in a circle, mark the cut line.

If you want to cut exactly at an angle of 90 degrees, then solve the problem quickly with the help of paper or masking tape again. Wrap around the pipe so that the ends match. Make a smooth marking and saw off.

How to cut a profile pipe evenly?

Masters advise using a square when cutting a profile pipe. To do this, apply the square in turn to the sides, and smoothly rotate and apply marks. After actions, fix a pipe and cut. Prepare yourself a template that will come in handy in the future and save time. It is better to produce an action with a grinder, so the cut will be smoother.

How to cut a cast iron pipe?

When working with a cast iron pipe, keep in mind that this is a fragile material. Therefore, we will introduce a method by which it will be possible to cut such a metal without damage.

Before starting work, make notes for the cut, as in the work with steel pipes. Place a wooden beam for support. Walk the grinder around the circumference of the pipe, making small cuts. Then take the chisels, insert into the groove and apply a strong blow with a hammer. Keep in mind that bakelite cutting discs are used to cut cast iron pipes.

If there is no grinder on hand to cut a cast-iron sewer pipe or other purposes, use a hacksaw for metal, chisels or special pipe cutters.

How to cut a gas pipe?

Cutting the gas pipe is a dangerous action, so it is best to entrust it to professionals. But if you are confident in the forces, then for cutting metal, take a grinder, welding, hacksaw, gas welding.

Trimming instruction:

• Before work, shut off the riser with gas supply. Then release the rest of the gas from the pipe. To do this, set the gas on the burners and wait until it goes out.
• After the steps, cut. Using the welding method, the metal base burns out when exposed to high temperature. The result is fast and efficient. But remember that cutting or rooting gas pipes again needs experience.

Methods for cutting large diameter pipes

There are a number of reliable tools for cutting large diameter pipes, such as sewers. Next, we consider some of them in detail:

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

How to cut the pipe along correctly?

A quick way to cut a pipe along with a grinder:

• Focus on markup.
• Use for this case a masking thread that has found distribution when marking walls.
• Before starting work, fix the pipe and with small movements, carefully saw the pipe.
• Better not be in a hurry, but gently and slowly process the parts of the pipe, so the cutting disc does not come 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, since there is a high probability of material deformation. For cutting use fillers, for example, sand. Actions can be carried out using a grinder, a special machine.

Summing up, we emphasizethat the cutting of metal pipes is a complicated process, but every interested master can strengthen it. Using the advice of professionals, you can easily cope with the cut of 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 basic thing that you should remember when starting such an action is safety. When starting work, wear a special suit (casing), mask or goggles. Hands should be protected from sparks, so use tight gloves.

Sometimes you need to trim a particular part or product at a certain angle. As a rule, you need to trim baguettes, fillets, platbands, plinths and other similar interior elements at an angle of 45 degrees. Everyone can cope with this task. The main thing is not to rush, not to be nervous and everything will work out.

Buy finished corner elements

Of course, the easiest way is not to suffer with trimming one or another part, but to buy ready-made, not requiring processing and trimming. Such parts and elements are sold everywhere in large supermarkets or smaller stores.

For example, with regard to baguette or fillet, special corner elements are sold to them that fit perfectly into the corner and do not need to be trimmed. It is enough to simply stick them in their place and press them down well.

The method of joining platbands without undercutting

Platbands today often do not cut at an angle to then dock with each other, but make a joint at right angles. This method of joining platbands does not require any special trimming, which is very convenient. In addition, this method looks more modern and attractive.

Miter cuts using a miter box

If, nevertheless, it is necessary to cut one or another part at an angle, then it is worth stocking up with a miter box - the simplest device that looks like a small box. The miter box has slots that are designed for a saw or a long sharp knife. Of course, these slots are made so that they form an even and accurate angle of 45 degrees.

However, the miter box can have many slots at once, from different angles. This is convenient, because with the help of a single device, you can cut any parts at different angles.

There are adjustable miter boxes on sale. The slots of such a miter box can be adjusted, which allows the master to set exactly the angle that is currently required. In particular, it is quite simple to translate the slots of such a miter box to a position of 45 degrees.

Now the workpiece can be cut elementarily. A baguette, platband or baseboard is placed in the miter box, after which the saw is inserted into the slots and the excess is cut off elementarily. The angle is ultimately perfect, exactly 45 degrees.

What to do if there is no bite? Very simple. You need to make a template according to which it will not be difficult to transfer the necessary markup to the workpieces. As a template, you can choose a thick cardboard or something else that will be appropriate in this case.

Cutting parts at an angle with a protractor

You can trim the part at an angle using a protractor. This is a measuring tool that is easy to use, and which is designed specifically to measure angles or make the necessary marking on certain parts. The protractor is applied to the part, mark the corner and make markings with a pencil. With this markup, cutting the workpiece at the right angle is not difficult.

Using patterns

If there is no protractor, miter box or ready-made corner elements, you will have to look for a suitable template. Of course, the template should have the right angle. It is applied to the workpiece and the workpiece is marked with a pencil. This is one of the easiest ways to achieve the desired result.

In-place pruning

Not always the walls, floor and ceiling will be in practice perfectly even. Most often they have irregularities. For this reason, there is no need to cut the workpieces at clear and precise angles, because they still will not fit perfectly.

Instead, it is sometimes convenient to trim the same ceiling plinth in place. That is, first one plinth plank is glued, cut it in the corner, and the second plank is cut under it.

Of course, it’s hardly possible to cut off the workpiece perfectly. However, if a small gap appears in the corner, it can always be covered with putty or gypsum plaster. Nothing special.
