[0002] Gas pipes have the characteristics of convenient installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, can be bent arbitrarily without deformation and gas blockage, etc. The surface soft protective layer material has the characteristics of safer, easier to clean and beautiful. The service life of the stainless steel threaded connection metal hose is 8 years. In the municipal pipe material market in China, plastic pipes are developing steadily. PE gas pipes, PP-R gas pipes, and UPVC gas pipes all occupy a place. Among them, the strong development momentum of PE pipes is the most remarkable, and their application fields are also very extensive.

[0003] Most of the existing gas pipes have a structure where the pipe body is directly exposed to the outside, or a rubber layer is added outside the pipe body for simple protection.
