Why do Hainan municipal pipelines prefer double wall corrugated pipes for drainage pipes? The following editor will tell you this secret. HDPE double wall corrugated pipe for drainage is a new type of pipe used for building outdoor drainage and municipal sewage drainage, which takes polyethylene resin as the main raw material, adds appropriate additives, and is extruded. Light weight, low drainage resistance, high compressive strength, corrosion resistance

Hainan steel mesh skeleton pipe has strong resistance to external pressure. The outer wall is in a circular corrugated structure, which greatly increases the ring stiffness of the pipe, thus enhancing the resistance of the pipe to soil load. In this performance, HDPE double wall corrugated pipe has obvious advantages compared with other pipes. Low project cost Under the condition of the same load, HDPE double wall corrugated pipe only needs a thinner pipe wall

Hainan municipal pipeline 1. Trenching machine is used as a sludge processor with rigidity and sealing in the middle of the pipeline. It acts as a gusher to cross the pipeline under the effect of gas or liquid working pressure, eliminating the dirt in the pipeline together. In this way, the wall thickness and smoothness standards are specified, and the sediment cannot be too much. Therefore, it is mostly used for nuclear power generation and industrial metal sewage treatment pipeline cleaning
