How to cut a plastic pipe along Rivne?

I am simple at first glance operation. Cutting pipes in practice discovers a lot of nuances and pitfalls. Not so. Just cut off the tube evenly:

It is very important to choose a cutting method for each specific case and special equipment. It is divided into individual, domestic and industrial

For individual use

Used in households, private construction and small business. Deal with small and average diameters (up to 250 mm) used in systems

Rezaki. They are used to cut off the polymer pipe up to 75 mm. For an even and neat cut, they have a gear mechanism. The workpiece is first clamped by a shelter, which reliably fixes it and does not allow to leave the cutting line. Disk cutter. Suitable for ventilation and sewer polymer pipes with a diameter of up to 200 mm. A blade is not a secate type, but in the form of a disk rolling on the surface of the workpiece. The incision is carried out at several revolutions. Not suitable for metal.Plastic rolling, since a thin metal liner can mix. Guillotine. A flat oblique knife moves in the guides and allows you to smoothly cut off the required length in one pass. Produced both with an electric drive that provides greater performance, and with manual. Kryazuvka for metal. A classic locksmith tool allows you to cut off the preparation clamped in a vice

When using it is important to lead the saw smoothly, with constant effort and without distortions. The burrs formed after work with a hacksaw should be cleaned with a file. Corner grinder, corner grinder

In everyday life, it is called “corner grinder”. This universal tool on the teeth of any materials and diameters. In order to cut the pipe with a corner grinder, special abrasive cutting discs are used. Electric jigsaw. A very popular instrument among home masters can cut pipes, but due to the departure of a flexible blade to the side of accuracy you will only have to dream of a saber’s saw. The tool has not yet become widely distributed among Russian masters. The adjustable emphasis of the saw and its powerful blade allow you to cut off the rental even by weight and close to the wall.

How to cut a pipe evenly

In order for the cut from a general purpose tool to be even, special devices should be used to fix the workpiece. It can be templates, vise or chose

In addition, it is very important to properly mark the future cut and during work to ensure that the fishing line for the trimmer cut does not go to the side

For industrial use

Such equipment is used in production, where the volumes of work are large or you have to cut large diameter pipes. In order to cut off evenly, use:

  • Lathe. Suitable for high.Precision cutting of workpieces, removing chamfers, performing ledges, transitions of diameters and other shaped processing. Allows the lathe and cut the thread, both internal and external. The length of the part is limited by the departure of the machine of the machine. Diameter. The fist of the cartridge.
  • Ribbon machines. They are used in order to cut off a large diameter pipe without extracting it from a trench or a collector point. Work on deformed products.
  • Disk cutting machines. Highly automated installation with a pendulum saw and the mechanism for feeding blanks. It is often included in the production line, used for high.Performance rolling of rolling into equal pieces.
  • Manual disk installations. Mobile equipment is used to cut off the rental exactly right at the installation site. They are equipped with a multifunctional clamp that allows you to reliably fix products of different diameters and cut them out evenly without damaging the edges. Turning table allows you to cut exactly at an arbitrary angle. The most advanced models are equipped with an orbital welding system. This allows you to not only cut off, but also connect the segments.

How to cut pipes from different metals at 45 degrees and 90 degrees

How to cut a pipe at a certain angle? About the straightforward cut has already been said. Next, we consider the methods of separating tubular blanks from various metals using locksmithing metal. In addition to the convenience of cutting, the knock minimizes the number of sawdust, which is important if the work is carried out at home.

Locksmith consists of two knots:

  • Manual hacksaw, which has the upper tubular guides, which allow you to hold the tool strictly perpendicular to the direction of cutting;
  • Colesh.Like housing, in which holes are pre.Made. Slots on both sides to help the employee make accurate corner cuts (usually 90 ° and 45 °, but there are rushed with an angle on which angular cuts in the angle range from 100 to 1150) can be performed).

Distinguish cast and stamped wort. The first, although cheaper, they work poorly in the conditions of periodically arising stresses of bending.

It is important to correctly choose the performance of a hacksaw. For angular cuts, only a precision tool with the upper guides is suitable, which are additionally safe from the bend with spring limiters.

The choice of the size of the locksmith was made according to the following parameters:

  • The width of the rushed, which determines the maximum blank diameter.
  • The length of the stirred, with an increase in which the accuracy of the segment increases.
  • The presence of an angler.
  • The depth and width of the through cuts in the side walls of the channel: the deeper they are, the less sensitively the cutting modes. The state of lubrication, increase the temperature of the hacksaw and the workpiece. On the other hand, when to saw off the pipes of large diameter, the enlarged width of the sawdust will adversely affect accuracy.
  • The case of the case: steel (cast or stamped) cubes should be unequivocally preferred with plastic, although the latter and easier.

How to cut a pipe at an angle of 45 degrees? When working with locksmith stupid, first you need to cut the material, and then, making sure of the wall perpendicularity, gradually increase the pressure force on the hacksaw cloth.

Cutting technology

As a rule, the volumes and complexity of the work that are coming to the home master does not require the use of high.Performance and expensive equipment of the production level. In the manufacture of the frame of the greenhouse, you can completely cut the pipes with a corner grinder or a traditional manual hacksaw.

Each type of cut has its own nuances, and some require special tricks.

At right angles

The accuracy of the cut is largely determined by a qualitatively made marking. Experienced craftsmen advise to marry the cutting lines not with a pencil, but with a painting tape, observing the following sequence of actions:

  • Set aside the required size and put a small mark with a marker or pencil.
  • Gently, applying to the mark, glue the part with masking tape in a circle. The edges of the paper must converge without a shift. This is a sign that the paper is sticking correctly. If the edges have not come down, the tape needs to be re.Packed.
  • Reliably fix the workpiece to exclude its movements and ponds during work. To fix, use a vice, clamps.
  • A cut (smaller) piece of the workpiece should be left by weight so that it does not clamp a blade or disk.
  • The incision starts from the upper part.
  • Corner grinder disk (or hacksaw cloth) is carried out exactly along the edge of the painting tape, without deviating to the side.

This is allowed to cut off the required length.

If the diameter is large, then the marking is performed in the same way, but cut in parts, sectors of 30-60 °. After cutting the next fastening sector, weaken and turn the pipe. Then they fix again and continue to cut off from the place where the previous sector ended. To make it smooth, special attention should be paid to the beginning of the cut, avoiding steps and sickness.

Oblique section under 45 °

Cut the end of the pipe at exactly 45 ° is possible without the use of complex devices. It is enough to apply locksmith. You will need to do the following:

  • Cut a paper sheet in the shape of a square.
  • Fold the diagonal. The rectangular isosceles triangle will learn.
  • Wrap the workpiece with a leaf so that the triangle has a perpendicular to the axis, and the hypotenuse forms an ascending spiral.
  • Fix the sheet with tape.
  • Fix the workpiece and cut off along the oblique edge of the sheet. It will turn out under 45 °.

There is another folk method. The end of the workpiece is immersed in a container with a liquid at the required angle. Cut off along the border of the dipped and dry sections.

If you need to cut off not perpendicularly, then it is better to use an old carpentry tool. A knock.

This is a P-shaped template, in the side walls of which slots are already made at the given corners. The pipe is rested on the far from the master, the wall was stuck and pressed there with a hand or a manual clamp. The canvas of the hand saws are made in the appropriate grooves and saw. If necessary, cut off from a different angle, you can make additional cuts in the walls.

Which tool can be used to cut plastic pipes

If we take into account that the people in our country are artisan, then for cutting pipes they manage to use the most unimaginable improvised means. But do not think that such a cut contributes to the good quality of the future pipeline. Therefore, we consider tools that allow the most qualitatively to cut plastic pipes:

  • Kryzuvka for metal;
  • Self.Locking knife (with small cloves);
  • Scissors for cutting pipes made of plastic;
  • Roller.Type pipeline;
  • Battery pipeline;
  • Guillotine pipeline.

Cutting pipes with a hacksaw for metal or knife should not be considered seriously, since their use leads to the fact that the end of the pipe is blinking, burrs that have to be eliminated with sandpaper or cleansing with a knife. In any case, the quality of the cut suffers. These methods can be used for single cuts. If the pipeline has a complex configuration and many joints of individual sections, then these tools are better not to use. Pipe cutting scissors are used mainly for cutting pipes from plastic polymers.

The sharpened knife blade is fixed only on one side of the tool. At the site of the second blade there is a fairly wide base with a slot intended to receive a cutting plate. Work with such scissors is carried out exclusively due to the muscular strength of a person. A rounded rack is placed between the handles of the scissors, which, after closing the handles of the scissors, pushes the blade in the direction of the base.The pipe cutting process is as follows:

  • On the surface of the pipes, they put a well.Visible mark, putting the cut place with it;
  • The base is located on top of this mark, controlling through the cut of the base its position;
  • Then, having attached strength, they crash into the pipe and, gradually increasing the effort, produce the final cut of the pipe.

Cutting technique

Self.Cutting can be carried out with products with a diameter of 5 to 30 cm. So, if the product does not fall into these boundaries, it is best to contact professionals.

When conducting any such manipulations, it is important to remember the basic rules:

sewer, pipe, using, stir
  • Metal.Plastic products are very sensitive to temperature, so that some problems may occur in hot or cold weather. The material is easily compressed and expands, which makes it difficult to determine the true size.
  • Metal.Plastic, like polypropylene pipes, can be cut by any improvised means. But in order to avoid various negative consequences, it is best to do this with special tools.
  • An excellent tool is a special self.Staining knife. But if it is planned to carry out work to replace one section with another, it is better to abandon the tool in favor of scissors.
  • The material is quite fragile. The attachment of too much effort is fraught with the appearance of cracks or specific deformations. The permissible load can be seen in the passport of the product that was issued at the time of installation of the water supply.
  • The type of cutting directly depends on the shares of metal and plasticity in the product. If the metal is larger, then when cutting friction should be as few as possible. Otherwise, a large fraction of plastic implies a greater intensity of work with great friction.
  • Before starting work, it is necessary to make sure that water or gas does not go through the pipe. You need to block all the taps and wait a bit.
  • After completion of work, you need to cleanly clean the inside of garbage, which can lead to bolts or break specialized equipment.

The use of electronic cutting tools is not considered reasonable, since the specifics of the material for this is not designed. You can cope with manual means.

When working with PVC pipes, it is often required to cut them. One of the advantages of PVC is that they are easy to cut with a wide variety of tools, which relatively simplifies the work. For pvc cutting, you will not need special devices or complex tools. To cope with the task well, you can use various tools, including hacksaws, pipelines and end saws.

  • Also, instead of a vise, you can use another type of clamping device to fix the pipe in a certain place on your workbench. Use what is available.
  • So that you have a sufficient gap, clamp it a few centimeters from the cut. If possible, you can clamp on both sides of the cut, but holding one side a few centimeters from the line of the alleged section will make it completely safe.

Make a mark where you need to cut. With the help of a permanent marker, clearly indicate where you are going to cut the pipe. Do not worry that the ink will remain, later you can wipe them with medical alcohol if the appearance is so important.

Put a hacksaw with teeth to the pipe. Place the hacksaw on the mark and hold the handle tightly, then with the help of the other hand press on the upper part of the hacksaw, pressing its teeth into the pipe. You need to start sawing from the right place in order to avoid extra unnecessary backwater.

Sew the pipe confidently. Start the cut, carefully following the process so that the hacksaw does not go from the mark that you put on the pipe initially. Drink quickly enough so that the incision is deepened, but not so much that the teeth jumping the cut that you perform. You must be able to cut PVC relatively quickly.

  • Sometimes, for the use of scissors type pipelines, extremely strong hands are needed and it would be easier to use a saw of any type. The acquisition of a locking.Type cutter will greatly facilitate your work.

Place the pipe in the lower part of the pipeline made in the form of a crescent. To insert a pipe into it, the pipeline has an open rounded edge, and when you press the button on its handle, the blade comes out from there. Mark the desired section of the cut, then to start the section, insert the pipe into the receiving opening of the pipeline.

Pull the blade on the pipe. To get a blade, press the trigger handle on the pipeline handle and cut the pipe in half. For stability when cutting, hold the pipe with the other hand. You should not be overstrained at the same time.

Consider the use of the User and saw for more accurate cuts. The saw can be used for PVC products when you need to perform many specific, small cuts. Use a dentate saw suitable for the section of the section and based on the availability of endings. If in doubt, select a standard wooden blade size of 10 teeth 2.5 cm, which is found in most endings. Although, this will depend on a particular brand and the type of a purchased saw.

Place the PVC pipe under the blade in the right place of the cut. Speed ​​is the easiest way to use in the world, since when it is used to use a fishing line for a cutting trimmer for your convenience, it will be previously noted next to it. You cannot miss.

Fasten the pipe using a clamping device. Run the blade and reduce the speed to the average. Upon completion of the cut, the process can be easily repeated, when necessary, performing additional cuts.

Scabble for metal.

The most common way. The only drawback. The cut can turn out to be a curve to avoid this, it is advisable not to saw immediately, but to turn the pipe 3-6 times. It will look approximately like this:

How to disconnect the cast.Iron pipes of sewage

First of all, you should get rid of the cement castle (sealing of the bell. The camber of the packley and the device of the castle). The work is not easy-it requires almost tenderness due to the structure of cast iron, scattering from gross treatment, despite its strength. The cement castle is destroyed by a screwdriver or chisel.

Cast iron is cut with a corner grinder. First dismantle the pipe. Then, in the unit remaining in the bell, two cuts are carefully made (at a distance of 100 mm from each other) with a small circle. Pieces are knocked out of the bell with a chisel (they knock on it with a hammer. Pounding with a hammer directly on the cast iron is strictly prohibited).

Important! Do not use gross power. Break the entire system. Cast iron is fragile. You need to act very carefully.

Even if the bell on the tee, which goes to replace, should be carefully so as not to damage the lower pipe included in the same tee (unless, of course, you are going to replace everything from the neighbors). Having removed all the fragments, the bell is thoroughly cleaned of rust, dirt, etc.

Cast iron risers were once massively put in apartment buildings (the designs have been preserved to this day). Certain details were produced at the factory. They also performed the clogging. Used sulfur for this. Such a system can be disassembled only with the use of open fire. At the same time, sulfur allocates toxic pairs. The respirator is necessary. We do not advise doing such work independently. It is actually dangerous.

How to cut a sewer pipe

Plastic structures are cut with a saw, corner grinding (knife, ax), then removing the chamfer with grief in half in half. The remaining Zazubrins violate the integrity of the sealing cuff, which is why leaks subsequently arise. There is a special tool for cutting. A pipeline.

The tool is different. You need to buy not any kind of, but suitable in diameter and designed for a certain material (PND, metal.Plastic, fiberglass, etc. D.). Special scissors are also released for this purpose. Devices with a fracking mechanism are twice as long as usual, but make the perfect slice, which is extremely important for the sewer system.

Marking a square

If there is a square at hand, then you must first determine the exact fishing line for the trimmer of the pipe end, including the profile. By applying the tool and smoothly shifting it on the surface, we get a fishing line for a cutting cut of 45 degrees. The same technique is used with a 30 degree square.

How can you cut pipes

We have a smart people, it manages to adapt the most unimaginable tools and adaptations for cutting the material. But cutting with improvised tool is unable to provide the quality of the pipeline.

For this reason, you need to know what can be used for this and what is not worth it:

  • Kryzuvka for metal;
  • Pipelines of different designs;
  • Self.Shackle knife;
  • Band-saw;
  • Corner grinder;
  • Electrician;
  • Scissors for plastic.

The use of a hacksaw for metal for metal is seriously considered, when working, the end becomes terry, there are burrs on it, which will have to be removed using sandpaper or knife. No matter how you do, the quality of the cut is bad. It is permissible to use it for single cuts. In the manufacture of a pipeline with many joints and turns, it is better to prepare a special tool.

Specialists use special scissors. Their sharp blade is placed on one side device. The second blade replaces the base with a special slot into which the cutting plate passes. When working with this tool, the hand gets tired, quickly cut a lot of material with them is very difficult. They cannot be cut thick pipes, the maximum diameter is not more than 42 mm.

When using a corner grinder, you need to prepare a disk for metal. When working, it is important to accurately distribute the effort. It is impossible to press hard on the corner grinder.

Electricity. The easiest way to work if there is no special pipeline. But the ability to make an uneven cut sharply increases, for this reason it is desirable to gradually turn the pipe during operation.
