How to scan a pipe at any angle. Pipe cutting at forty-five degrees or another angle

In various situations, masters of the household level often come to the question of proper marking for accurate cutting of pipe billets at an angle of 45 degrees. Today there is a huge selection of tools for both the domestic and industrial pipe cutting process at any angle. The cost of such devices is quite high.

How to cut a pipe at an angle

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

Pipe marking and cutting

Tool for cutting pipes at an angle

The very process of marking the cut workpiece seems quite a simple matter. But it should be noted that the allowed rounding during the manual marking process will create an irreparable error after trimming, which will lead to inconsistency and the formation of defective products. In order to eliminate such defects, it is required to make a simple tool for clearly marking profile parts. At the same time, cutting products at an angle of 450 is much simpler.
An ordinary section of a steel profile of a p-shaped shape, made at an angle of 45 degrees, will become a reliable tool for accurate cutting of pipes. At the same time, the profile size 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 right angle, you must have the following additional tool:

1. Goniometer;
2. Scriber for metal;
3. Bulgarian;
4. Cutting disc;
5. File.

How to cut a pipe at an angle

It’s easy 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 an angle gauge, an angle of 45 degrees will be marked at any end of the segment. Next, grinder to cut the profile. The resulting template must be tested for accuracy. In case of deviations, file the measuring device with a file.

Using such a self-made marking tool, the process is much simplified, especially with a large volume. For marking, it is only necessary to place the cut profile pipe in the fixture made, to draw the correct angle using the scriber. In the process of marking, 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 the straight marked lines are cut. Such templates for trimming pipes at an angle of 45 degrees will save enough time and money.

Marking and cutting circular pipes

In the case of cutting round pipes at an angle of 45 degrees, a tool made for rectangular pipes does not quite fit. For a more accurate - streamlined drawing of the cut line at an angle, it is recommended to use a paper piece, which is wound on the workpiece.

Patterns are developed in the modern world with the help of computer programs.

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

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 cut the pipe correctly 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 the 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:

• Turn off the riser with gas before working. 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 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 regulated by mechanical devices. It is important to note that the models of the machine differ in shape, therefore, before using, consider the ratio of dimensions to the pipe.
• Gas cutting is the most popular option for cutting larger diameter pipes, sheet metal. The cut occurs 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 delicately 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, fillers are used, 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 cutting pipes of various sizes and materials. Also do not forget to process the edges of the pipes after cutting with a file or sandpaper. And the most basic thing that you should remember when starting such an action is safety. When starting to work, wear a special suit (casing), mask or goggles. Hands should be protected from sparks, so use tight gloves.

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 this 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 of marking, it is recommended to 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 template 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 specified 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 wish, 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 is not suitable.

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, an electric motor with a torch 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 for fastening 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 to cut 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 machine provides cutting 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, a special table can be used 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, after which they perform a cut.

Thermal guillotines support cutting at an angle, and this is their advantage. However, for working 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 with a water tank instead of a pattern

This method of marking 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 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 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 along the 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 in handling 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 using the marking material, and after the marking is done 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 grinder with a mounted cutting disc.

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 you need to cut a pipe of large diameter, you can use a number of special devices and tools. 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 effect of a high intensity flame, and the waste produced in 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 cutting 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 completely 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.

Pipe cutting 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 from two sides, after which the straight marking lines are cut. This device for cutting pipes at an angle significantly saves time and money.

Marking and cutting pipes 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:

When installing the pipeline, it is often necessary to cut the pipe at an angle. Moreover, the angle should have exactly the degree that is necessary for the design. If the angle is not manufactured correctly, it is impossible to manufacture exactly the dimensions of the pipeline that were supposed to be performed. For example, the pipe during installation will rotate 45 degrees, therefore, you need to know how to cut the pipe at 45 degrees. For this we need marking tools, a grinder or a hacksaw for metal.

One of the easiest 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 with a folded sheet so that the edges of the diagonals are opposite each other. Thus, on the smaller side of the sheet we have an angle of 45 degrees. We take any marking tool and mark the place of the future section of the pipe along the sheet line. To prevent the markings from being accidentally erased, you can use a narrow tape. This marking method is convenient for a long pipe of large diameter, and the cut location of which is somewhere in the middle.

Using a water tank

What if we are dealing with a pipe of small diameter, and it is necessary 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 tank. Then we just need to carefully lower the edge of the pipe into the water and tilt it to the mark on the tank. We take out the pipe, mark the line of contact with water, and boldly cut according to the marking. This method is good for marking a large number of pipes. A ready-made template from a container with water will speed up the process of our work.

Computer program to help

I would also like to consider the markup method using a computer program. This is a rather complicated method for those who are not used to working with a computer. It requires knowledge of the PC, the availability of programs for scans and drawings. We start by completing a drawing with the size of the circle and the slope. We make the so-called virtual template.

Then, using a printer, print the image on a sheet of paper. The larger the diameter of the pipe, the more there will be sheets with a marking. Scissors cut out all parts of the drawing and with adhesive tape, glue them. The finished template is applied to the pipe, and on the edge of the paper we do the marking. This markup method is considered one of the most accurate. If the computer does not have such programs, you can use the Internet. You can download a pattern for marking on the network. It also needs to be printed on a printer and cut. Wrap the finished piece around the pipe and mark it.

If the pipe is profile

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 profile with a larger diameter. Take a small segment of a profile pipe and use an angle meter to mark an angle of 45 degrees. We cut off according to the marking with a grinder and grind the edges so that during work we do not get injured on the burrs. All that remains for us is to insert a profile of a smaller diameter into the template and, having made the markup, cut it off.

In this article, we looked at how to cut a pipe at 45 degrees. Using one of the above methods, markup and cut. For a more even cut, it is better to use a grinder. When cutting by welding, experience will be required, otherwise, unevenness will result in slices. In extreme cases, you can use a hacksaw for metal. Currently, there are many different devices for cutting pipes at an angle, but buying them requires extra costs. It’s easier and cheaper to make a template once, and use it as needed.
