How to unroll a pipe at any angle. Cutting pipe at forty-five degrees or another angle

In various situations, household-level craftsmen often come to the issue of correct marking for accurate cutting of pipe blanks at an angle of 45 degrees. Today there is a huge selection of tools, both for the domestic and industrial process of cutting pipes at any angle. The cost of such devices can be quite high.

How to cut a pipe at an angle

It is proposed to consider methods of marking workpieces for cutting at an angle of 45 degrees in a domestic environment without the use of expensive professional equipment.

Pipe marking and cutting

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 eliminate such defects, it is required to make a simple tool for clear marking of the profile parts. In this case, cutting products at an angle of 450 is much easier.
A regular 45-degree U-shaped steel section is a reliable tool for accurate pipe cutting. 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 carry out such a tool marking the correct angle, you must also have the following additional tool:

1. Protractor;
2. Scraper for metal;
3. Bulgarian;
4. Cutting disc;
5. File.

How to cut a pipe at an angle

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. By means of a goniometer, at any end of the segment, it will mark an angle of 45 degrees. Next, cut off the profile with a grinder. The resulting template needs to be tested for accuracy. In case of deviations, file the measuring tool.

Using such a hand-made marking tool greatly simplifies the process, especially with a large volume. To mark, it is only necessary to place the cut profile pipe in the made device and draw the correct angle with a scribe. During the marking process, the length of the products is controlled. Next, you need to cut the pipe clearly along the marking lines using a grinder. It is worth noting that at first the pipe is cut along the diagonal marks on both sides, then straight marked lines are cut. These 45-degree pipe cutting templates will save you a lot of time and money.

Marking and cutting circular pipes

When cutting round pipes at an angle of 45 degrees, the tool made for rectangular pipes is not quite suitable. For a more accurate - streamlined drawing of the cutting line at an angle, it is recommended to use a paper template that is wound around the workpiece.

Patterns are developed in the modern world using computer programs.

The cutting line changes depending on the angle and diameter of the pipe set in the program. Common patterns can be found on the Internet or remember our painted rulers from school.

When dealing with construction or plumbing tasks, you need to know how to cut the pipe straight with a grinder. In the article, we will consider quick and easy ways of how to properly cut a 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 more often required when laying water and heating pipes. Steel, cast iron pipes that are cylindrical in shape are often used. In installation work, rectangular or shaped pipes are used. However, you should correctly cut the pipe with a grinder, so that you can easily connect it later. Therefore, you should carefully mark the pipe.

Some craftsmen try to mark the place of the cut using a tape measure, but we warn you that the result is likely to be negative. And for a positive result, consider the following professional recommendation.

Take a sheet of paper or cardboard, preferably A4, fold it diagonally and wrap it around the pipe where you plan to cut it evenly. The edges of the paper must be in perfect alignment 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 the 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 again. Wrap around the pipe so the ends match. Make even lines and saw off.

How to cut a profile pipe straight?

Masters advise using a square when cutting a profile pipe. To do this, apply the square in turn to the sides, and turn and mark with smooth movements. After action, fix the pipe and cut. Prepare yourself a template that will come in handy in the future and save time. It is better to perform the 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 it is a brittle material. Therefore, we will point out a way with which it will be possible to cut such a metal without damage.

Before starting work, mark the cut as you would for steel pipes. Place a piece of wood for support. Work the grinder around the circumference of the pipe, making small cuts. Then take the chisels, insert them into the groove and hit hard with a hammer. Note that bakelite-based cut-off wheels 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 metal hacksaw, chisels or special pipe cutters.

How to cut a gas pipe?

Cutting a gas pipe is dangerous, so it is best to entrust it to professionals. But if you are confident in your strength, then take a grinder, welding, hacksaw, gas welding to cut the metal.

Pruning instruction:

• Shut off the gas riser before work. 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 the steps taken, cut. Using the welding method, the metal base burns out when exposed to high temperature. The result is fast and effective. But remember that cutting or rooting gas pipes again takes experience.

Methods for cutting large diameter pipes

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

• The grinder is an inexpensive and affordable option, but it is considered not the safest when 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 material removal begins. The clamping force is adjusted using mechanical devices. It is important to note that machine models differ in shape, so consider the ratio with the pipe before use.
• Flame cutting is the most popular option for cutting large diameter pipes, 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 the pipe lengthwise correctly?

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

• Focus on the markup.
• Use for such a case the painter's thread, which has found widespread use when marking walls.
• Before starting work, fix the pipe and with small movements, carefully saw the pipe.
• Better not to rush, but delicately and slowly process the parts of the pipe, so 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, since there is a high probability of deformation of the material. Fillers such as sand are used for cutting. Actions can be carried out using a grinder, a special machine.

Summing up, we emphasize that cutting metal pipes is a complicated process, but anyone who wants to can enhance it. With the advice of a professional, you can easily handle cutting pipes in a variety of sizes and materials. Also remember to file or sandpaper the edges of the pipes after cutting. 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 goggles. Hands should also be reliably protected from sparks, so use thick gloves.

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

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. In this case, you can control the angle with an ordinary protractor.

It is very often necessary to cut pipes in the process of working with these installation elements. A popular tool for such cases is the so-called grinder. Cuts straight and at an angle with this tool

The most common installation requirement is cutting plumbing or other pipes at an angle of 45º. Let's find out what devices can be used to cut at this and another angle.

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 size printer paper is well suited for creating patterns. Previously, the sheet is marked out under a square using a ruler. The size of the diagonal of the square must be equal to the circumference of the pipe to be cut. The excess parts of the sheet are cut off.

The easiest way to get a pipe marking line is to make a 45 degree cut. A regular sheet of paper is used, which is superimposed on the pipe body in the cutting area

1. Bend the sheet diagonally by aligning opposite corners.
2. Rotate the resulting triangle so that the hypotenuse line is perpendicular to the pipe axis.
3. In this position, wrap the tubular 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 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 better markup convenience, it is recommended to use thick, but soft paper. Paronite and similar materials can also be used.

Programs for calculating cutting angles

Curve cutting technology allows you to obtain different cutting angles. But to form a pattern 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. Such programs print out patterns for cutting pipes on a printer.

This is how the window of a computer program looks like, which calculates the cut angle for a circular section. Based on the results of the calculation, a pattern is drawn, which can be printed by a printer. A template is cut according to the pattern

A simple calculation program created on the basis of the MS Excel application allows you to calculate and compose 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.

An example of a pattern obtained by the calculation method in the popular Excel program. The calculation of the points of the curve 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, often used in everyday life, mainly for working with wood. It is called a miter box. So, the 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 required 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 in width increased by the thickness of the first board.
3. Assemble a structure in the form of an inverted letter "P" from three boards, where the first board is installed as a base.
4. In the central part of the structure, mark a rectangle, the 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.

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 accuracy of the cut. It is recommended to make the walls of the tool from a material of higher strength than wood.

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

The advantages of the method are obvious - simplicity, ease of making a tool (miter box), cost-effectiveness, 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 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 under the cut with a grinder.

Simple tooling for cutting

Round and rectangular metal products with sufficiently 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 attached to the motor shaft. In turn, the electric motor with a cutter is part of the entire equipment, which includes a work table, a pendulum support, a clamp.

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

To install the pipe at the desired angle with its subsequent fastening, a conventional 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 turning mechanism sets the required cutting angle (for example, using a ruler and protractor).
2. The position found is fixed with clamping screws.
3. A pipe is laid between the short and long corners and pressed with the clamp screw.
4. Voltage is applied to the electric motor.
5. By applying slight pressure to the cutter blade, the pipe is cut to the desired location.

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 domestic use, increased noise, work with pipes of only small and medium diameters. In addition, the process of cutting with tooling 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 products of rectangular cross-section, it is recommended to prepare in advance the template cuts of the corners. They are easy to make from a metal corner, having previously marked with the same protractor.

Cutting rectangular pipes (profile elements) at the desired angles is usually done according to templates. These templates are made from metal corners of different sizes.

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 marked line.

Precision cutting machines

Among the branded devices that could be used in everyday life to perform an angle cuts, 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.

Convenient and productive machine for cutting small and medium-sized pipes. The cutter is made on the basis of a strip steel blade, which can be installed for making cuts at an angle

The machine supports setting the cutting angle from 0 to 45º. The procedure is carried out using a tape belt at 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. The maximum permissible diameter of the cut round pipe is 65 mm.

Industrial models (for example BSM)

There are dedicated industrial machines for precise bevel cutting operations. A good example: devices manufactured under the BSM brand. The machine tools are manufactured by the German company Rexinger. True, the BSM series machines are designed exclusively for working with polypropylene pipes of sufficiently 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 products of large diameters, but has equipment for processing pipes from 50 mm. The machine cuts in a wide range of angles

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

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 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 cutting line is leveled, the values ​​of the required angle are adjusted. This approach is economically disadvantageous, 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 method.

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 a cut is performed.

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

Video: how to cut a pipe correctly

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

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

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

An incorrect pipe cut will lead to the impossibility of mounting a 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 tools for marking and a grinder (it can be replaced with a hacksaw for metal).

Marking the corner with a paper sheet

Layout on paper is one of the simplest ways to accomplish a 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 section.

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

Method of marking using a container with water instead of a template

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. Along it, the pipe is cut at an angle. This method is best suited for jobs where multiple striping is required.

Using a 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, which indicates the transverse dimensions of the product, as well as the planned cut angle. You need to get a virtual template.

Print it out on a printer. And here it should be understood that the larger the diameter of the pipe, the more sheets will be required for printing 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 apply the markings.

This method of solving the problem is highly accurate. All the necessary programs can be downloaded from the Internet, they are free to download and use. It will also be possible to find a template for cutting pipes at an angle. All that remains is to print and cut it. To carry out the marking, the piece is simply wrapped around the pipe.

How to cut a profile pipe at an angle

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

A small section of a shaped pipe will be required. On it, using a protractor, mark an angle of 45 degrees. Now, with the help of a grinder, you need to cut off part of the workpiece along the marked line. The cut edges need to be sanded and defects removed. All that remains is to insert the original product into the bevel cutting template. Then you need to apply a marking along the cut line of the 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 markup has already been completed, it is recommended to use a grinder. With its help, it will turn out to make an even cut. You can replace it with a hacksaw for metal. It will also be possible to cut the product by welding, but experience in handling the tool is needed, otherwise there will be irregularities.

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

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

Cutting 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. This cutting of 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 shaped pipes of rectangular or square section are more often used. The main problem here is that in order for the connected elements to coincide, the cut must be as even as possible, which means that especially close attention should be paid to the marking of the material.

In the event that 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. Next, using the marking material, a number of dotted lines are applied and after the marking is completed around the entire circumference, the template can be removed.

If the profile pipe is to be cut, 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. After sawing off the template, the pipes to be cut can simply be inserted into it and marked out. This approach will significantly save work time and it will be convenient to cut a profile pipe at 45 degrees.

As for what to use when carrying out work, here it is worth choosing the most suitable and familiar. It can be a simple one, or a grinder with an installed cutting disc.

Cutting at 90 degrees

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 video shows the process of cutting a pipe at 90 degrees.

How to cut a profile pipe straight

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 turned, and the markings are applied. Further, the pipe must be fixed immovably and you can start work.

Any suitable tool can be used for sawing. If you have to cut a lot of pipes, 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 a large diameter pipe needs to be cut, a variety of special attachments and tools can be used. This may be required if, for example, a pipeline needs to be repaired.

• Bulgarian. The use of a grinder is justified from the point of view of the availability of the tool and the relative cheapness of work. However, in this case, you 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 referred to as 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 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.

There are other options for accomplishing the task, such as using 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 cutting off such a pipe, you need to determine an algorithm of actions.

• We mark it in the same way as steel pipes.
• At the place where the cut is made, a wooden beam must be placed 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 line, forming a fairly flat cut point, which, if necessary, can be further processed.

How to cut along

Another frequently asked question is how to cut the pipe lengthwise with a grinder. 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. The sawing process itself must be done carefully and slowly, 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 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 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 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 the safety rules.

In various jobs, home craftsmen are sometimes faced with 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 consider ways of marking pipes for a 45-degree cut at home, without using expensive devices.

Marking and cutting a profile pipe

At first glance, marking a profile pipe seems to be a fairly simple matter. However, rounded corners when manually marking out will give a serious error. For this reason, it will be more convenient to make a simple device for marking a profile pipe. Cutting metal pipe at 45 ° when using this device, it is simplified at times.

A device for cutting pipes at forty-five degrees is a segment of a U-shaped steel profile, cut off at an angle of 45 degrees. The dimensions of the profile are selected in such a way that the pipe to be marked can fit freely into it. To make this device, you will need the following tools:

• Protractor;
• Scraper 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 workpiece with a length of about 20-30 centimeters is cut from the profile. Using a goniometer, an angle of 45 degrees is marked on one of the ends of the segment. After marking, using a grinder, the profile is cut. On the received template, it is necessary to check the accuracy of the angle. If necessary, the template is modified with a file.

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

The pipe is cut along diagonal lines on both sides, after which straight marking lines are cut. This angled pipe cutter saves a lot of time and money.

Marking and cutting pipes at a circular angle

When you need to cut a round pipe at a 45 degree angle, the tool discussed above may not work. In this case, the pipe is cut at 45 degrees using paper templates wrapped around the workpiece. You can download a template for marking.

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. Whichever 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:

When installing a pipeline, it is often necessary to cut the pipe at an angle. Moreover, the angle must have exactly the degree that is necessary for the structure. If the corner is made incorrectly, it is impossible to make exactly the dimensions of the pipeline that were supposed to be made. For example, a pipe will rotate 45 degrees during installation, therefore, you need to know how to cut a pipe at 45 degrees. To do this, we need marking tools, a grinder or a hacksaw for metal.

One of the simplest methods is to mark the corner with a piece of paper. We fold the square sheet strictly diagonally. We take the pipe and wrap it in a folded sheet so that the edges of the diagonals are opposite each other. Thus, on the smaller side of the sheet, we got an angle of 45 degrees. We take any marking tool and mark the place of the future pipe cut along the sheet line. To prevent the markings from accidentally rubbing off, you can use a narrow tape. This method of marking is convenient for a long pipe with a large diameter, and the cut of which is somewhere in the middle.

Using a container with water

What 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 starting work, it is necessary to calculate the angle of inclination and make a mark on the container. Next, we just have to carefully lower the edge of the pipe into the water and tilt it towards the mark on the container. We take out the pipe, mark the line of contact with the water, and boldly cut along the markings. This method is good for marking a large 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 rather difficult method for those who are not used to working with a computer. It requires knowledge of a PC, the availability of programs for scans and drawings. We start by making a drawing indicating the size of the circle and the slope. We make a so-called virtual template.

Then, using the printer, we print the image on a sheet of paper. The larger the pipe diameter, the more marking sheets there will be. We cut out all parts of the drawing with scissors and with the help of scotch tape, glue them. The finished template is applied to the pipe, and we make markings along the edge of the paper. This markup method is considered one of the most accurate. If your computer does not have such programs, you can use the Internet. You can download a template for marking on the net. It also needs to be printed and cut out. We wrap the finished piece around the pipe and make the 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 large error. The best way out of this situation is to make a template from the same larger diameter profile. Take a small section of a profile pipe and use a protractor to mark an angle of 45 degrees. We cut off according to the markings with a grinder and grind the edges so that we do not get hurt by the burrs during work. Then we just need to insert a profile of a smaller diameter into the template and, having made a marking, cut it off.

In this article, we looked at how to cut a pipe at 45 degrees. Using one of the above methods, mark up and cut. For a smoother cut, it is better to use a grinder. When cutting with welding, experience is required, otherwise unevenness will turn out on the cuts. As a last resort, you can use a hacksaw for metal. There are many different angled pipe cutting attachments on the market today, but they are expensive to purchase. It is easier and cheaper to make a template for yourself once and use it as needed.
