When repairing or laying new communications, you often have to look for the answer to the question: how to cut the pipe exactly? There are many simple methods that can achieve the desired result when cutting pipes from any material.
How to cut a pipe straight at a 90 degree angle
There are several nuances when cutting a pipe to the desired size. It is necessary to take into account: the material of manufacture, the angle at which it should be cut. If the angle is straight, then the markup is performed as follows:
- Measure the required length, draw a line with chalk or a marker.
- Wrap the pipe with masking tape or a sheet of paper according to the level of the mark. You need to make sure that the edges of the tape coincide with each other. This will ensure a clean cut.
- Cut the pipe with a grinder. Exactly how the markup is made is possible only if the cut is made not at once, but in several steps. It is necessary after a small cut to turn the pipe by 20 - 40 degrees until a full turn occurs.
It is not advisable to make markup using a tape measure. When wrapped around the pipe, it breaks, preventing it from being drawn evenlycircumference.
How to mark up at a 45 degree angle
Making 45 degree markings is more difficult. A small diameter pipe can be marked with water. If the piece is small, then this option is suitable. A pipe is lowered into a container with water at an angle of 45 degrees. Water leaves a mark on the surface that needs to be duplicated with a marker.
Using a paper template, you can mark a pipe of any diameter. It is done as follows:
- A circle is drawn on graph paper equal to the diameter of the pipe.
- The base of the circle will be the X axis. On it you need to draw a segment equal to the length of the circle, so that the middle coincides with the axis of symmetry of the circle.
- The resulting line must be divided into 16 equal segments.
- The line of symmetry of the circle, which will be the Y axis, is also divided into 8 segments.
- From the points that form the segments, you need to make projections: from the points on the X axis - vertical, and from the points on the Y axis - horizontal. The intersections of these projections must be connected with a smooth line.
- The resulting figure must be cut with scissors.
The template is wrapped around the pipe and secured with masking tape.
It is difficult to cut straight pipe at an angle. As a rule, a grinder with a large diameter wheel is used, even for cutting thin pipes. The larger circle leads less to the side.
An interesting way to cut a plastic pipe
There are many tools for working with plastic pipes. There isspecial scissors that cut pipes with a diameter of up to 75 mm.
You can use a hacksaw or just cut it off with a grinder. But all of these methods have drawbacks. Scissors cut at an angle of 90 degrees. But how to cut exactly a plastic pipe if a different angle is required or a large diameter does not allow them to be used? If you cut with a hacksaw, then the slippery plastic surface does not allow you to cut according to the markings. It is possible to make a device devoid of the listed disadvantages.
This tool combines a pipe guide (miter box) and a nichrome thread cutting attachment.
A nichrome thread is installed on the miter box at the right angle. It is connected to the electrical network through a ballast resistance or a rheostat. This will allow you to select the desired temperature. After heating the wire red-hot, the workpiece must be lowered into the miter box. This will cut the pipe smoothly like clockwork.
