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

Buy ready-made corner elements

Of course, the easiest way is not to bother with trimming this or that part, but to buy a ready-made one that does not need processing or trimming. Such parts and elements are sold today everywhere in large supermarkets or smaller stores.

For example, as for baguettes or fillets, special corner elements are sold for them that fit perfectly into the corner and do not need to be trimmed. They just need to be glued into place and pressed well.

Method of joining platbands without trimming

Today, platbands are often not cut at an angle and then joined together, but the joints are made at right angles. This method of connecting platbands does not require any special trimming, which is very convenient. In addition, this method looks more modern and attractive.

Cutting at an angle using a miter box

If you still need to cut this or that part at an angle, then you should stock up on a miter box - a simple 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 in such a way that they form an even and exact angle at 45 degrees.

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

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

Now you can trim the workpiece simply. A baguette, platband or plinth is placed in the miter box, after which a saw is inserted into the slots and the excess is simply cut off. The angle ends up being perfect, exactly 45 degrees.

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

Cutting parts at an angle using a protractor

You can cut the part at an angle using a protractor. This measuring tool, which is easy to use, and which is designed specifically for measuring corners or making the necessary markings on certain parts. The protractor is applied to the part, the angle is marked and the markings are made with a pencil. Using these markings, cutting the workpiece at the desired angle will not be difficult.

Using Templates

If you don’t have a protractor, miter box or ready-made corner elements, you’ll have to look for a suitable template. Of course, the template must have the desired angle. It is applied to the workpiece and the workpiece is marked with a pencil. This is one of the most simple ways achieve the desired result.

Trimming "on the spot"

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

Instead, it is sometimes convenient to trim the same ceiling plinth local. That is, first they glue one strip of the plinth, trim it in the corner, and cut the second strip under it.

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

You will need

• - miter box;
• - hacksaw;
• - wooden blank;
• - protractor;
• - pencil;
• - a clamp or screws and a screwdriver.

Instructions

Prepare a corner template that will help you easily make an accurate cut of a piece of wood at an angle of 45 degrees. This device is a profile in the form of an inverted letter “P”; On its sides there are through slots for a hacksaw. They are usually located at angles of 45, 60 and 90 degrees. More complex miter boxes are additionally equipped with arbitrary fixed slots, or have a rotating design - it allows you to install the saw in the optimal position.

Buy ready-made carpentry tool at a hardware store with a wooden, metal or plastic tray. For a novice master this is best option. If desired, you can make a simple miter box from three planed boards or plywood strips (thickness - about 1.5-2 cm).

Drill several holes in the walls of the future miter box, apply wood glue to the ends and assemble the box (tray) of the miter box. Secure the corner template with screws. The walls of the instrument must lie strictly parallel to one another; the bottom and each side form clear perpendiculars.

Mark a 45 degree angle with a pencil and add additional groove lines if necessary. To avoid mistakes in your calculations, use a protractor.

The most important thing is the slots. It is recommended to perform them with the same hacksaw that will subsequently be used to make cuts in the finished miter box. Start sawing without putting too much pressure on the working tool and hold the blade. First saw through one side, then the opposite.

Start processing lumber. Secure the miter box to a workbench or work table with a clamp (clamps for fixing parts) or screws. Then make a mark for the future cut on the slats (boards, plinths) and place the workpiece in the box. Press it firmly against one of the side walls of the template, aligning the marks with the 45-degree angle slot.

Insert the hacksaw into the grooves of the miter box and cut the workpiece. The saw will be limited to fixed cuts and you will get a clean and precise cut.

When cutting skirting boards, make sure that the corners in the room are really straight. If the walls are very uneven, the angle of the cut on the workpieces should be adjusted. Measure the joints with a goniometer interior walls and divide the result in half (the joint of the skirting boards is “in a miter”). To make an accurate cut, it is recommended to make grooves with a given angle homemade miter box. Another option is store-bought rotary tool, which allows you to change the angle from 0 to 180 degrees in steps of about 15 degrees.

During installation and plumbing work, it is often necessary to cut workpieces at a certain angle. Changing the direction of the cut line is necessary for further joining and welding with other pipes of the same configuration, or for installation of shut-off and control valves.

It is worth considering that precision cutting at the desired angle is necessary to obtain high density rolled metal connections. To do this, you need to have the necessary equipment, a high-quality pipe cutter and have relevant experience in carrying out pipe processing work.

In this article we will look at techniques for cutting pipes at various angles.

1. Methods for marking pipes at an angle of 45 degrees

Cutting pipe blanks at an angle of 45° is most in demand when installing heating mains, sewer networks, gas pipeline systems. For these purposes, pipes made of ferrous metals and stainless steels cylindrical section, small and medium diameter - 20-500 mm.

One of the main tasks when cutting pipes at an angle of 45 degrees is the accuracy of measuring the angle and the evenness of the pipe cut, so that when joining, the joined elements coincide with an accuracy of a millimeter. This is especially true for thin-walled pipes - with the slightest cutting error, the walls of the connected pipes will not be able to connect in the desired configuration. Therefore, close attention must be paid to cutting accuracy.

Pipe marking round section

If you don’t have a production template, you can use a pattern made from a square paper sheet. To mark the pipe, perform the following steps:

1. Fold the square sheet strictly diagonally, aligning opposite corners. The length of the diagonal of the pattern should be equal to the circumference of the workpiece.
2. The folded sheet is wrapped around the pipe. It is important to ensure that the side of the pattern located closer to the end of the workpiece is strictly perpendicular to the central axis.
3. Dotted markings are made at the location of the future cut.
4. Next, the pipe is cut.

Important! When considering cutting methods, it is necessary to take into account the material of the pipes. It is easier to cut copper and steel blanks with a diameter of up to 65 mm using paper patterns. To mark thick-walled steel pipes of large cross-section, it is better to use paronite templates.

Marking square and rectangular pipes

To make a pattern for marking profile pipe It is more expedient to use a similar workpiece only with a larger cross-section. Marking on the workpiece is performed once using an engineering ruler or protractor. Into the cavity ready-made template the profile is inserted, marking and subsequent cutting are performed.

2. Marking pipes at an angle of 90 degrees

Marking the pipe at a 90 degree angle is quite easy. If necessary, you can use a sheet of paper: the sheet is wrapped on the pipe, secured and marked. It is important to ensure that the edges of the sheet coincide along the entire circumference, then the cut will be even.

How to cut a profile pipe at an angle of 90 degrees?

To cut square or rectangular pipes, it is preferable to use a triangle. This device alternately marks with a marker on each side of the profile. After drawing the dotted line, the pipe is cut.

3. Marking pipes at other angles

To cut pipes at angles of other values, you will need patterns with the appropriate values. You can prepare a template using Excel or other computer programs by entering the pipe diameter, desired angle, etc. in the appropriate interface.

In calculation programs, you can calculate the cutting of pipes of any diameter and at any angle. But most often this method is used to create patterns for cutting pipes of small and medium diameter. For cutting pipes large diameter and in large volumes it is preferable to use programmable cutting machines.

How to cut a pipe using the collar method?

Often when installing water supply networks it is required pipe blanks, having a cut at the end in the form of a triangle. This pipe configuration is necessary to connect to another round pipe at a right angle.

To perform a collar cut proceed as follows:

• The circumference of the pipe is measured.
• The pipe is cut at an angle of 90 degrees.
• At the end of the pipe, equidistant points are marked, which are located at angles of 90 and 180 degrees relative to each other.
• Calculations are performed: the diameter of the pipe is divided by three.
• The resulting value is plotted from two diametrically located points and marked with dots.
• These points are connected to other smooth arcs.
• After cutting with a pipe cutting tool, semicircular segments are separated, which are ready for subsequent welding work.

How to order a pipe cutting tool

For advice on the selection of equipment for cutting pipes, please contact our managers.

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

For an inexperienced master the best option would be to purchase a ready-made miter box at a hardware store. At home, it can be made from three planed boards or plywood.

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

Step 3: we mark slots at different angles to cut laminate, trim, etc.

The application of the slots will affect the accuracy of the work performed in the future. Therefore, this process must be approached with special care. It is advisable to make cuts using the same hacksaw that will be used to perform the work.

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

It is necessary to secure the finished corner template on the desktop using a clamp. Next, markings for the future cut should be applied to the workpiece. Next, you need to align the workpiece with the 45-degree slot inside the miter box and press firmly.

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

Subtleties of working with a miter box and various materials

When sawing elements such as baseboards, it is not always necessary to make a 90-degree cut. After all, the walls in the room may be uneven. Before sawing the baseboard, it is necessary to adjust the angle of the cut.

Thus, the article described and characterized the sawing process wooden materials using a miter box.

Pipes are a widely used building material. They are used in installation different systems. A common occurrence during the installation process is when pipes need to be joined at an angle. However, the technology for producing such work does not seem quite common. To create this connection configuration, the pipes must be cut at an angle. Let's look at how such operations are performed and what cutting methods exist.

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

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

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

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

Paper pattern for pipe

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

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

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

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

Programs for calculating cutting angles

Pattern cutting technology allows you to obtain different cutting angles. But to form a pattern at angles other than 45º, you will already need 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 master from making calculations. Patterns for cutting pipes are printed by such programs on a printer.

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

A simple calculation program created on the basis of the MS Excel application allows you to calculate and draw up a pattern for almost any pipe diameter and required cutting angle. All the user needs to do is enter the appropriate values ​​in the “Outer diameter” and “Cut angle” cells. Using these parameters, a pattern will be generated that can be sent for printing.

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

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

Miter box for cutting pipes

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

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

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

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

The advantages of the method are obvious - simplicity, ease of making a tool (miter box), efficiency, versatility. The disadvantages of working with this type of equipment are the need to adjust the dimensions of the miter box to the pipe diameter, provided that an accurate cut is performed. That is, for each pipe you will have to make your own tool.

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

Simple cutting equipment

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

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

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

Pipe laying and cutting procedure:

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

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

The nuances of working with a rectangular section

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

Cutting rectangular pipes ( profile elements) under the right angles usually done according to templates. Such templates are made from metal corners different sizes

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

Precision cutting devices

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

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

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

Industrial models (using the example of BSM)

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

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

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

Application of thermal methods

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

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

Usually, after thermal cutting, products undergo additional processing. The cut line is aligned and the required angle values ​​are adjusted. This approach is economically unprofitable, as it is accompanied by additional costs for mechanical processing. As a rule, thermal cutting techniques are used in industrial production conditions. True, housing and communal services also often resort to this technique.

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

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

Video: how to cut a pipe correctly

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

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

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

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

Marking a corner with a piece of paper

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

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

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

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

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

Using the computer program

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

Print it on your printer. And here it is worth understanding 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 the pages and glue them together; it is best to use stationery tape for this. All that remains is to attach the template to the pipe and apply the markings.

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 template for cutting pipes at an angle. All you have to do is print it and cut it out. To mark, the pattern is simply wrapped around the pipe.

How to cut a profile pipe at an angle

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

You will need a small piece of profile pipe. Using a protractor, mark a 45 degree angle on it. Now, using a grinder, you need to cut off part of the workpiece along the marked line. The edges of the cut need to be sanded and defects eliminated. All that remains is to simply insert the original product into the template for cutting pipes at an angle. Then you need to apply markings along the cut line of the larger profile. And the pipe itself is cut along it.

The text describes ways 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 you can make an even cut. You can replace it with a hacksaw. You can also cut the product by welding, but you need experience in handling the tool, otherwise there will be unevenness.

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 a pipe. This could be plumbing work, laying pipelines or installing heating systems, but in any case it is necessary to know how to cut a pipe evenly. Some features of performing this task will be discussed further.

45 degree cutting

One of the particular examples similar situation is the need to cut the metal pipe at an angle of 45 degrees. Such cutting of material is often required when laying water pipes or heating systems. In this case, you have to deal with steel pipes. For these purposes, conventional cylindrical pipes are usually used. If we are talking about the installation of some kind of metal structures, then profile pipes of rectangular or square cross-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 smooth as possible, which means that especially close attention should be paid to marking the material.

In cases where 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 wrapped around the pipe with the 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 marking material, a series of dotted lines is applied and after the marking is completed along the entire circumference, the template can be removed.

If you have to cut a profile pipe, then it is advisable to make a special template from the same pipe, but with a larger cross-section. In this case, you will only have to use the measuring devices once. To apply markings you will need to use a protractor or a construction square. After sawing off the template, the pipes to be cut can simply be inserted into it and marked. This approach will significantly save work time and cutting a profile pipe at 45 degrees will be convenient.

As for what to use when carrying out work, you should choose the most suitable and familiar one. It can be a simple one or an angle grinder with a cutting disc installed.

90 degree cutting

When the need arises to cut at 90 degrees, the situation is even simpler. In the case of cylindrical elements, you can use the same sheet of paper that is used to wrap the pipe as a template. It is important to ensure that the edge of the sheet is smooth and matches the entire circumference. After marking is applied, the element to be cut is fixed and the cut is made.

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

How to cut a profile pipe evenly

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

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

Large diameter pipe cutting

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

• Bulgarian. The use of an angle grinder is justified from the point of view of the availability of tools and the comparative cheapness of the work. However, you should not count on greater productivity in this case; in addition, carrying out work in this way is associated with considerable risk.
• Roller machine. Such devices are also often called pipe cutters. In essence, such a device is the same grinder, but more suitable for this type of work. The machine includes a special frame where the element to be cut is fixed, as well as a holder with installed cutting rollers, which do the actual 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 due to the action of a high-intensity flame, and the waste produced is blown away by gas pressure. The method can be considered the most practical and effective.

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

How to cut a cast iron pipe

If the pipe is made of cast iron, then in order to cut it smoothly 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 an algorithm of actions.

• We mark in the same way as steel pipes.
• At the cutting site, you need to place a wooden beam as a support.
• Next you need to make a cut of a few millimeters around the entire circumference.
• After this, 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 lengthwise

Another frequently asked question is how to evenly cut a pipe lengthwise with a grinder. Here the algorithm of actions will be approximately the same as for transverse cutting. It is important to pay attention to marking. You can, for example, use painting 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 slowly, since when sawing long elements there is a high probability of the cutting disc slipping from the marking line.

How to cut thin-walled pipes

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

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

During 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 discuss ways to mark pipes for a 45-degree cut at home, without the use of expensive equipment.

Marking and cutting profile pipes

Marking a profile pipe at first glance seems quite simple. However, rounded corners when marking manually will give a serious error. For this reason, it will be more convenient to make a simple device for marking the profile pipe. Cutting metal pipes at 45° When using this device, it becomes much easier.

Forty-five degree pipe cutting device is a piece of U-shaped steel profile, cut at an angle of 45 degrees. The profile dimensions are selected in such a way that the marked pipe fits freely into it. To make this device you will need the following tools:

• Goniometer;
• Metal scriber;
• Angle grinder (grinder);
• Cutting disc;
• File.

Making such a device for cutting pipes is quite simple. It is convenient to use for slicing large quantity pipes, for example for welding frames.

A blank about 20-30 centimeters long is cut from the profile. Using a protractor, an angle of 45 degrees is marked at one of the ends of the segment. After marking, the profile is cut using a grinder. It is necessary to check the accuracy of the angle on the resulting template. If necessary, the template is modified with a file.

Cutting a pipe at forty-five degrees using such a template is greatly simplified. The pipe blank is placed into the template and marked using a scriber. When marking, it is necessary to check the length of the workpiece. After this, 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 cutting device saves a lot of time and money.

Marking and cutting round pipes at an angle

When it is necessary to cut a round pipe at an angle of 45 degrees, the device discussed above may not be suitable. In this case, cutting the pipe at 45 degrees is done using paper patterns wrapped around the workpiece. The marking pattern can be downloaded.

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