Problems solved by technology

[0002] Existing polyethylene pipes are easy to react with oxidants such as chlorine gas and hypochlorous acid in the fluid carried by the pipes, resulting in oxidative degradation, shortening the service life, and due to the limited external tension that the pipe body can withstand, it will lead to cracking Phenomenon, it cannot be applied to places with high water pressure, which makes it difficult to implement durability

Embodiment Construction

[0015] In order to further illustrate the present invention, further describe below in conjunction with accompanying drawing:

[0016] Such as figure 1 with figure 2 As shown, a cross-linked polyethylene pipe of the present invention includes a pipe body 1, a protective inner layer 2 and an outer layer 3, the pipe body 1 is equidistantly distributed along the axial direction with at least one through hole 4, and the protective inner layer A cross-linked intermediate layer 5 is provided on the outer wall of the cross-linked intermediate layer 5 , a sandwich wall 6 for partition is provided between the through holes 4 and adjacent through holes 4 , and an outer layer 3 is provided on the outer wall of the cross-linked intermediate layer 5 . There are three through holes 4 . Both the protective inner layer 2 and the cross-linked middle layer 5, and the cross-linked middle layer 5 and the outer layer 3 are bonded to each other to form an integral body. The cross-linked inter...

Abstract

The invention discloses a crosslinked polyethylene pipe. The crosslinked polyethylene pipe comprises a pipe body, a protective inner layer and an outer layer, and is characterized in that at least one through hole is formed in the pipe body in the axial direction at equal intervals; a crosslinked middle layer is arranged on the outer wall of the protective inner layer; interlayer walls for partitioning are arranged between the through holes and the adjacent through holes; and the outer layer is arranged on the outer wall of the crosslinked middle layer. The crosslinked polyethylene pipe effectively improves the oxidative degradation resistance, prolongs the service life, can effectively counteract the external tension generated by the water pressure in the pipe body, and largely enhances the tension stress of the pipe body.

Description

technical field [0001] The invention relates to a cross-linked polyethylene pipe. Background technique [0002] Existing polyethylene pipes are easy to react with oxidants such as chlorine gas and hypochlorous acid in the fluid carried by the pipes, resulting in oxidative degradation, shortening the service life, and due to the limited external tension that the pipe body can withstand, it will lead to cracking Phenomenon, it cannot be applied to places with high water pressure, which will cause difficulties in implementing durability. Contents of the invention [0003] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical cross-linked polyethylene pipe, which effectively improves the ability to resist oxidation and degradation, prolongs the service life, and can effectively offset the water pressure generated in the pipe. The external tension greatly increases the tension resistance of the pipe bo...
