HSBC d double-wall corrugated pipe
D double-wall corrugated pipe has been widely used in many developed countries. D double-wall corrugated pipe is suitable for municipal sewage, agricultural irrigation, chemical industry, industrial wastewater discharge, community drainage projects, water conservancy, highway preparatory work Burial and power cable protection and other fields. D double-wall corrugated pipe is made of high-density polyethylene by simultaneously extruding the corrugated outer wall and the smooth inner wall at one time. It has good corrosion resistance, high insulation performance, strong low temperature resistance, good sealing performance, and no leakage. It has the characteristics of light weight, not easy to be damaged and easy to install, making it an ideal substitute for concrete pipes and cast iron pipes.
. The product has novel materials, reasonable structure and high strength
. Compared with flat-wall corrugated pipes, double-wall corrugated pipes have the characteristics of lighter weight, less material and lower energy consumption
. The smooth inner wall of the double-wall corrugated pipe has a large flow rate (compared with cast iron pipes and concrete pipes) and uses a smaller diameter
. The pipe adopts flexible interface to resist uneven settlement
. The pipe village interface adopts socket-sealed connection, which is more convenient for on-site transportation and construction (below), reducing the construction labor intensity and speeding up the construction progress
. It has strong chemical resistance and can be used in special occasions
. There is no scaling in the pipe and no dredging is required to reduce maintenance costs
. Under normal circumstances, construction does not require comprehensive concrete foundation work, and the cost is low and the service life is long
