Problems solved by technology

[0002] At present, pipes in the market are commonly used heat-conducting components in the field of industrial equipment, and are widely used in various equipment. According to different application occasions, pipes should have long life, high precision, high rigidity, low noise, high wear resistance and other characteristics. Pipes are widely used in pipes, but due to the harsh working environment of pipes, a large amount of dust accumulates and wears pipes at high speed during work, which seriously affects the service life of pipes, and a large amount of dust splashes out of the main body through the gap, wasting a lot of dust. It will increase the production cost, affect the normal length of the pipe, increase the failure rate, and reduce the working efficiency of the pipe. This problem is becoming more and more prominent
