How to cut plastic sewage pipe
In order to lay sewer pipes, you can not resort to the services of specialists, and do everything with your own hands.
The laying of sewer pipes with their own hands is carried out according to certain rules, the outdoor sewer has its own features.
First of all it is necessary to cut them into sections of desired length, then they need to be connected with each other by shaped elements. After the assembly of the pipeline is completed, it is attached to the wall.
What tool can be used for cutting plastic pipes
If we consider that the people in our country artisan, then to cut the pipe he manages to use the most unimaginable improvised means. But do not think that this cutting contributes to the good quality of the future pipeline. Therefore, let’s consider the tools that allow the best quality cutting of plastic pipes:
- hacksaw for metal;
- Self-sharpening knife (with fine teeth);
- scissors for cutting plastic pipes;
- Roller-type pipe cutter;
- cordless pipe cutter;
- guillotine pipe cutter.
Do not take pipe cutting with a hacksaw or a knife seriously as their use leads to flabby pipe ends, burrs appear and need to be removed with sandpaper or scraping with a knife.
Either way, the quality of the cut suffers. These methods can be used for single cuts. But if the pipeline has a complex configuration and many connections of individual sections, it is better not to use these tools. Pipe scissors are mostly used to cut plastic pipes.
The sharpened blade of the knife is attached to only one side of the tool. In place of the second blade, there is a fairly wide base with a slit designed to accept the cutting plate. Working with such scissors is made solely by the muscular power of a man. A rounded toothed rail is placed between the scissor handles, which pushes the blade in the direction of the base after the scissor handles are closed.The process of cutting pipe is as follows:
- A well noticeable marking is put on the surface of the pipe to mark the place of the cut;
- the base is placed over this mark, controlling its position through the slot in the base;
- then, using force, cut into the pipe and, gradually increasing the force, make the final cut of the pipe.
The advantages of the scissors are rather high efficiency and low cost of construction. But the disadvantage is considered a direct connection between the effectiveness of the tool and the physical strength of the person working with it. In addition, during the cut, you must monitor the smooth movement of the brush, otherwise the blade can simply slip off the toothed rail.
it is clear that with a large number of cuts the hand gets tired quickly, so the speed of work is reduced. In addition, you can’t cut large-diameter pipes with scissors. The maximum diameter of the processed pipes is 42 mm.
The roller pipe cutter is designed for large amounts of work.It looks just like a normal screw clamp with movable casters attached to the clamp. The cutting roller is located on the end of the screw of the clamp.
The pipe cutter is as efficient as the scissors. But unlike them, there is practically no physical effort involved. The cutting process itself is as follows:
- The cut is marked with a marker at the point of cut;
- The screw is unscrewed from the clamp, and the bracket is brought to the place of the cut;
- then the screw is tightened smoothly (so as not to break the pipe);
- After creating the necessary force on the cutting roller, the clamp begins to rotate around the pipe, while gently tightening the tensioning screw.
In this way the pipe is cut in a circular manner and the end of the pipe is very even and burr-free. The only danger when using the pipe cutter is the cracking of the pipe because the screw presses too hard.
Cordless pipe cutter, in fact, is a shear equipped with an electric motor. Such a tool allows you to cut a pipe without much effort in 6 to 8 seconds. But the diameter of the pipe to be cut is as small as with conventional hand shears.
The guillotine pipe cutter is used for pipes with a diameter of 63 to 350 mm. Practically no wall distortion or breakage occurs. The cutting process is as follows:
- mark the place of the cut on the pipe and insert it into the guillotine, securing it in a 30 to 60 degree angle;
- The guillotine blade, mounted on wheels, swings around it;
- after the first cut of the plastic, the blade plunges into the pipe with the help of the rotating screw handle, and thus finishes the cut of the pipe.
The cut is very even, with no burrs. The guillotine blades are easy to replace. The blades of modern guillotines are additionally coated with Teflon.
The simple rules of working with sewage
Theoretically disassembling plastic sewage pipes does not cause difficulties. Nevertheless, we recommend contacting the professionals. The problem is that in apartment buildings it is extremely difficult to agree with the neighbors. It is even more difficult to ensure that everyone adheres to the hard-earned agreement without exception. Professionals have their moves adjusted over the years. it takes only seconds to change important elements. Professionals also have a regular ear for determining “it’s about to pop” long before it falls over.
Dismantling of cast iron sewers is difficult in itself. Especially when they are standing parts whose perfect tightness was achieved in the Soviet factory. With such a system is the direct route to the professionals.
Cutting cast iron pipes with pipe cutters
For cutting cast iron pipes, there are specialized pipe cutters. For example Exact Pipecut. portable electric pipe cutters, for working with pipes of Ø 15. 360
Pipes made of steel, copper, cast iron, stainless steel and plastic can be cut with EXACT Pipecut 170, 200 and 360. Application of TST carbide disc in pipe cutters gives great advantage over traditional abrasive wheels. cutting speed is up to four times higher, no sparks when cutting, cutting without adding coolant to the cutting zone. For cutting cast iron pipes we use diamond tipped carbide discs.

When working with PVC pipe you often need to cut it. One advantage of PVC is that they are easy to cut with a wide variety of tools, which makes the job relatively easy. You don’t need any special fixtures or complicated tools to cut your PVC. You can use a variety of tools to do a good job, including hacksaws, pipe cutters, and end saws.
- You can also use another type of clamping device instead of a vice to clamp the pipe in a specific spot on your workbench. Use what’s available.
- To make sure you have enough clearance, clamp it a few inches away from the cut. If possible, you can clamp on both sides of the cut, but clamping one side a few inches from the line of the intended cut will make it completely safe.
Make a mark where you want to cut. Use a permanent marker to clearly indicate where you are going to cut the pipe. Don’t worry about leaving ink behind, you can wipe it off later with medical alcohol if appearance is so important.
Put the hacksaw with the teeth against the pipe. Place the hacksaw on the mark and hold the handle firmly, then use your other hand to push the top of the hacksaw, pushing its teeth into the pipe. You need to start cutting in the right place to avoid unnecessary scoring.
Saw the pipe with confidence. Begin the cut, keeping a close eye on the process so that the hacksaw does not move away from the mark you originally placed on the pipe. Saw fast enough to deepen the cut, but not so deep that the teeth jump over the cut you are making. You should be able to cut the PVC relatively quickly.
- Sometimes extremely strong hands are needed to use a scissor-type pipe cutter and it would be easier to use any type of saw. Getting a locking-type cutter will make your job a lot easier.
Place the pipe in the bottom of the pipe cutter, made in the shape of a crescent. To insert the pipe, the pipe cutter has an open, rounded edge, and when you press the button on the handle, the blade comes out. Mark the desired place of the cut, then to begin the cut, insert the pipe into the receiving hole of the pipe cutter.
Point blade at pipe. To release the blade, press the trigger handle on the pipe cutter handle and cut the pipe in half. Hold the pipe with your other hand for stability when cutting. You should not overstretch yourself in the process.
Consider using a trimmer and saw for more precise cuts. The saw can be used for PVC products when you need to make a lot of specific, small cuts. Use a serrated saw that is suitable for the kind of cut and based on the availability of trimmers. If in doubt, choose a standard 10 toothed 2.5 inch wood blade as you find on most pipe cutting machines. Although, this will depend on the particular brand and type of saw you purchased.
Place the PVC pipe under the blade at the desired cutting point. The cutter is the easiest tool in the world to use because when you use it, the cut trimmer line will be pre-marked next to it for your convenience. You won’t miss.
Secure the pipe with a clamping device. Start the blade and slow it down to medium speed. Once the cut is complete, the process can easily be repeated, making additional cuts as needed.
Cutting at an angle
In this case, we will tell you how to make a cut of the pipe at a 45º angle. Marking will be needed in this case too (more details: “How to cut square pipe. marking options for round and square bar pipe”).
To draw it, you will need a square piece of paper, which must be folded diagonally. The obtained triangle is looped around the pipe and fixed. So you get the angle of 45º.
Of course, you can try to lower the pipes at the right slope into the water, then the border of the wet surface will serve as a marking. However, it is best to use a special device for angular cutting. a jig.
Jigsaw has the shape of an inverted “P. It has pre-drilled holes with different angles in its opposite walls. Simply place the pipe inside the machine and cut through the selected slots with a hacksaw.
So it is quite easy to make a straight cut of a pipe from any material by yourself. In this case, there are only a few tricks, which will allow you to quickly and qualitatively perform all the work and build yourself the necessary object for the farm or dacha. Let’s also note that it is better to check your measurements a few times before you start cutting, because you can accidentally make a mistake and damage the material and incur additional financial losses.
Classification and types of pipe cutters
There are a huge number of household and industrial pipe cutters for plastic pipes, but the principle of their action usually boils down to two variants:
Roller tube cutters have from one to several dozens of cutting elements fixed on rigid or movable bases. As they move around the pipe, the rollers gradually deepen into the plastic wall until they completely cut it off.
Guillotine models are cheap, easy to use and are the most common types of pipe cutters used by professional installers
Structurally, roller models have practically no complex mechanical elements, so their price is quite low.
Guillotine devices have a strong cutting edge, which is pressed into the wall of the plastic pipe with a manual effort. Most models have a built-in ratchet mechanism that makes the cutting process smooth and relatively easy.
Naturally, the devices also differ in other parameters:
- the diameter of the processed pipes;
- The types of materials available for work;
- the maximum wall thickness that the device is able to cut;
- electric motor.
The maximum diameter of pipes that can be cut with manual devices is 110 mm. This is the thickness of the sewage pipe for the toilet or riser pipe inside the house. But most tools are limited to a diameter of 50-63 mm.
Roller pipe cutters are inconvenient because they require constant tightening of the screw, which is rather problematic when cutting thin pipes by weight
The maximum wall thickness of plastic pipe is limited only for roller pipe cutters, so their selection should be based on this parameter. Cutting wheels with necessary height of blade can be bought additionally.
The bonus of the roller models is their possible versatility in terms of materials to be mowed. There are pipe cutters that are designed specifically for working with plastic material. But there are also those that can cut steel, copper, stainless steel and other types of metals at the same time.
Electrically driven devices are expensive, so they are purchased mainly by professionals. But with sufficient financial resources, everyone can buy them and make the work of installing plastic distribution easier.
