Product Description

High-Quality and Economical Corrugated Pipe

Introduction:
HDPE double wall corrugated pipes is a new type of pipe with annular outer wall and smooth inner wall. Its main raw material is high-density polyethylene. This products are suitable for gravity and low pressure drainage system of urban or industrial sewage, sanitary sewage, rainwater drainage, etc. 

HDPE steel belt reinforced spiral corrugated pipes are the third generation of steel - plastic composite structure pipe prepared by two - step molding process. This product combines the rigidity of steel strips with the corrosion resistance of polyethylene for lighter weight and higher strength. The products can be widely used in urban sewage pipes, bridge and culvert road sewage and drainage pipes, agricultural irrigation pipes, water source water intake pipes and so on.
