How to cut the thread on the pipe and what you need for this

In life, often there are situations when you need to connect two pipes. This happens when it is necessary to replace the area where the leak occurred, or to change the water supply configuration, to reorganize the heating system, or there is a need to connect new devices, for example, an automatic boiler, washing machine, dishwasher. In each of these cases, without a question on how to cut the thread, you can not do without. We will try to answer it.

The tool that will be needed to cut the thread is simple and reliable. You may need a hacksaw for metal, a file and a pipe cutter with a ratchet, that is, with a device based on a so-called "pawl", allowing circular rotational movements of the plate relative to the pipe without making a full turn of the handle around it. In most cases, such a device is necessary, because usually with one of the sides at least the pipe is adjacent to the wall.

When choosing a tool for pipe thread, you should focus not on its external appeal, but on the country of manufacture. It is better to think about how to cut the carving, than about what impression the home will make a purchase.

Our friends in some countries with a rapidly developing economy very quickly learned to give their products an external gloss, without worrying about the proper quality of the materials of manufacture, and not always very meticulously adhering to technological discipline. The inscriptions "Made in Germany" or "... in Austria" should also not lead into temptation and delusion, especially if the price is a few dollars. The German tool is certainly very expensive, but you can write anything, anything, and anything. Therefore, it is recommended first of all to stop looking at not such brilliant, but strong and reliable instruments of Russian production. If the handle is not as long as the import pipe cutters, then this should not be embarrassing, the torque can be easily increased by putting a piece of pipe on it, possibly just trimmed.

Now directly on how to cut the thread. A set of dies with a marking in inches, ½ ", ¾", etc. is attached to the threaded tool. A suitable one can be picked up by eye or measured by a shank-circul tube, in general, it is not difficult.

It is important to observe three points:

- First, remove the file with a chamfer from the truncated edge of the pipe;

- Secondly, to put on the entrance plate, wider side, otherwise it will not go through the pipe;

- Thirdly, use grease.

The requirements for lubrication are not very stringent, it can be an ordinary car "working off", any technical oil, or even simple fat, is better unsalted. If the last condition is met, the work process will go much faster and require much less effort, and the risk of damage to the remaining pipe undergoing torsional deformation is significantly reduced.

When cutting a pipe, do not forget that the direction of rotation of the plate should be not only direct, but also reverse. Correctly to cut a carving on a pipe it is possible only so - there-back, clockwise and against, gradually moving forward. In order for this to be possible, there is a rotation direction switch on the ratchet ratchet.

And the last tip: figuring out how to cut the thread, get involved in the process itself, it is usually enough to go through three to four centimeters.
