[0015] Beneficial effects:

[0016] 1. In the utility model, the smooth anti-blocking layer and the spiral guide pattern are provided. The polytetrafluoroethylene material in the smooth anti-blocking layer has an extremely low friction coefficient, which can reduce the friction between the fluid and the pipe wall, thereby reducing the deposition of particles and impurities on the pipe wall. On the other hand, the spiral guide pattern located on the inner side of the smooth anti-blocking layer increases the turbulence of the fluid in the pipe, which helps to break the deposition of particles and make them move with the fluid, which helps to take away the sediment and prevent pipe blockage.

The insulation layer 105 is made of glass fiber, which has excellent thermal insulation performance and can prevent the external ambient temperature from affecting the fluid in the pipe and protect the fluid from temperature fluctuations. The wear-resistant layer 106 is made of polyimide, which has extremely high wear resistance and can protect the inner wall of the pipe from the wear of hard particles in the fluid and maintain the smoothness and integrity of the inner wall. Through the composite combination of these layers, the polyethylene pipe shows excellent performance in practical applications and meets various engineering needs.

[0028] When working, the polytetrafluoroethylene material in the smooth anti-blocking layer 102 has an extremely low friction coefficient, which can reduce the friction between the fluid and the pipe wall, thereby reducing the deposition of particles and impurities on the pipe wall. On the other hand, the spiral guide grooves 103 located on the inner side of the smooth anti-blocking layer 102 increase the turbulence of the fluid in the pipe, help break up the deposition of particles, make them move with the fluid, help carry away the sediment, and prevent pipe blockage.

Bolts or other connecting parts are used to pass through the sleeve holes 5 and the connecting holes 6 to fasten the two rings together, thereby realizing the connection of the pipes. If the pipes need to be replaced or maintenance needs to be performed, the connecting parts can be quickly loosened to remove the sleeve ring 3 and the embedded ring 4, thereby conveniently removing or replacing the pipe sections.
