[0003] The current compression -resistant plastic pipeline, such as PVC pipe, CPVC power pipe, etc., has widely adopted the method of setting a reinforcing compression mechanism on the outer wall of the pipeline to improve the compression resistance in practical application. Although PVC pipeline can improve the hoisting compression strength through reinforcing components such as reinforcing rings, connecting rods and reinforcing strips, these structures mainly improve the local strength during hoisting, and the overall long-term compression resistance of the pipeline in complex environments is limited. Especially in high temperature, high pressure or impact situations, the pipeline may still deform or rupture. SUMMARY

The anti-pressure protruding strips and the anti-pressure outer pipe are integrally designed, which reduces stress concentration and improves the uniformity and anti-pressure capacity of the structure. At the same time, the square design of the anti-pressure cavity and the arc-shaped design of the inner wall corners further optimize the anti-pressure capacity of the structure.
[0016] The design of the first arc-shaped cavity and the second arc-shaped cavity, and the addition of the anti-pressure reinforcing ribs, further improve the anti-pressure performance of the anti-pressure inner pipe and the anti-pressure outer pipe.
