High-strength corrosion-resistant polyethylene composite pipe

The utility model provides a high-strength corrosion-resistant polyethylene composite pipe, which relates to the technical field of composite pipes and comprises a pipe body, the outer side of the pipe body is connected with a heat insulation layer, the outer side of the heat insulation layer is connected with a tensile layer, the outer side of the tensile layer is connected with a waterproof layer, and the outer side of the waterproof layer is connected with a scratch-resistant layer. The anti-stretching layers are arranged on the two sides of the pipe body and the heat insulation layer, the fiber winding layers of the anti-stretching layers are located between the outer wrapping layer and the inner wrapping layer, and the two anti-stretching layers are arranged, so that the phenomenon that the whole pipe body cracks due to multiple times of long-time bending in the using process can be effectively avoided, the using strength of the product is improved, and the service life of the product is prolonged.
