Problems solved by technology

[0004] Compared with the drainage pipe, the sewage pipe has higher requirements on the pipeline. Compared with the water quality of the ordinary drainage pipe, the sewage discharged from the sewage pipe is more polluted. The sewage discharged from the sewage pipe often includes a large amount of Solid particles such as mud and dirt, these solid particles have been rubbed against the pipe wall for a long time, making the pipe wall thinner and rough

Abstract

The invention provides a frost-resistant composite blow-off pipe, comprising a pipe body, wherein the pipe body comprises a PE (polyethylene) layer serving as a main body, a graphite layer is arranged in the PE layer, a hydrophobic corrosion-resistant layer is arranged in the graphite layer, a temperature adjusting layer is arranged outside the PE layer, a thermal insulation layer is arranged outside the temperature adjusting layer, a PVDF (polyvinylidene fluoride) layer is arranged outside the thermal insulation layer, and a frost-proof layer is arranged outside the PVDF layer. The blow-off pipe provided by the invention is compounded with a multilayer structure, and is a cold-proof and frost-resistant multilayer blow-off pipe with a long service life.

Description

technical field [0001] The invention relates to a sewage discharge pipe, in particular to a cold-proof and freeze-resistant multi-layer sewage discharge pipe. Background technique [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. Widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. Plastic pipes are an important branch of many chemical building materials. From the perspective of different classifications of chemical materials, plastic pipes can be divided into polyethylene (PE) pi...
