Polyethylene armored drain pipe

Abstract

The invention provides a polyethylene armored drainage pipe which comprises a pipe body, the pipe body comprises an outer layer wall, a middle layer wall and an inner layer wall, the outer layer wall is an armored polyethylene layer wall, the middle layer wall is a vertical steel belt reinforcing rib, and the vertical steel belt reinforcing rib is evenly wound on the outer side of the inner layer wall. The vertical steel belt reinforcing ribs and the outer layer wall or the inner layer wall are connected into a whole through hot melting extrusion molding. The outer layer wall armored polyethylene layer can increase the mechanical compressive strength of the pipe body, can prevent mouse biting, and prevents the problem of inner layer wall damage caused by penetration through the armored base layer, and the armored pipe has significantly improved erosion resistance and external force resistance. The method is suitable for fluid conveying and ventilation pipes in various laying modes such as pipe rack support type, suspension type, buttress type and buried type. The compressive strength of the pipe can be remarkably improved, the safety performance is improved, and the pipe has the strength of steel and the toughness of plastic.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a polyethylene armored drainage pipe. Background technique [0002] In rainwater and sewage pipelines, ordinary plastic pipes are widely used due to their excellent corrosion resistance and convenient performance. However, the shortcomings of simple plastic pipes such as insufficient ring stiffness, high production costs, and unstable quality are gradually emerging. Come out, it is difficult to meet the use requirements of key engineering fields. Ordinary steel-plastic composite winding pipes mostly adopt a single-layer wall structure, which cannot effectively protect the working layer of the inner wall from the damage of the external environment. affect the service life. Although ordinary plastic-coated steel pipes are excellent in quality, their high cost and difficulty in producing large-diameter products have restricted their popularization and application in key engineering ...

Problems solved by technology

[0002] In rainwater and sewage pipelines, ordinary plastic pipes are widely used due to their excellent corrosion resistance and convenient performance. However, the disadvantages of simple plastic pipes such as insufficient ring stiffness, high production costs, and unstable quality are gradually emerging. come out, it is difficult to meet the use requirements of key engineering fields

Ordinary steel-plastic composite winding pipes mostly adopt a single-layer wall structure, which cannot effectively protect the working layer of the inner wall from the damage of the external environment.

Affect the service life

Although ordinary plastic-coated steel pipes are of excellent quality, their high cost and difficulties in the production of large-diameter products have restricted their popularization and application in key engineering fields such as large-scale water conservancy.
