They are designed to enhance their crack resistance and extend their service life.

[0003] The existing PE plastic pipe enhances the external pressure resistance of the pipe body by adding reinforcing ribs inside the pipe body, and enhances the internal pressure resistance of the pipe body by sandwiching an explosion-proof layer inside the pipe body.

Plug holes 17 are provided on the front and back sides of the interior of the extension plate 13. The insertion rod 15 and the elastic clip 16 are both slidably connected to the inside of the plug hole 17, so that the pressure-resistant sleeve 12 is firmly installed on the outside of the plastic pipe; one side of the inner side of the reinforcement ring 8 is fixedly connected to the elastic layer 11, the outside of the elastic layer 11 is fixedly connected to the stabilizing layer 10, and the outside of the stabilizing layer 10 is fixedly connected to the wear-resistant layer 9; the base layer 7 is made of high-density polyethylene; the depth of the reinforcement ring 8 embedded in the pipe body 1 is 2-3mm.

[0032] By installing a pressure-resistant sleeve 12 at intervals on the outside of the pipe body 1 and a base layer 7, a heat-insulating layer 6 and a temperature-resistant layer 5 made of high-density polyethylene in the pipe body 1, it can block high and low temperatures, ensuring that the temperature inside the pipeline is at a high deviation from the external temperature, so that the PE plastic pipe has high temperature resistance and crack resistance, a long service life, and strong corrosion resistance. The wear-resistant layer 2 9, the stabilizing layer 10 and the elastic layer 11 arranged inside the reinforcing ring 8 can ensure that the PE plastic pipe can be used normally when it is hit or damaged by the external environment, thereby improving the wear resistance and impact resistance of the PE plastic pipe, improving the high temperature resistance of the PE plastic pipe, preventing the PE plastic pipe from softening when exposed to a high temperature environment for a long time, and improving the applicable temperature conditions of the PE plastic pipe.
