HDPE Plastics-Steel Composite Drain Pipe with Double Plain Wall


I.Pipe introduction:

The spirally wound plastics-steel composite drain pipe with double plain wall is a kind of third-generation new plastics-steel drain pipe which is made by prefabricating the main raw material polyethylene (PE) into T-shaped plates, sheets and strips and winding the plates, sheets and strips on the pipe moulding machine and connecting them by welding, and meanwhile, rolling galvanized strip steel into a W-shaped steel strip and inserting the strip into the groove between two plates, sheets and strips and cladding the steel strip with PE as the outer wall of pipe.

The technical system of plastics-steel drain pipe with double plain wall has won 7 patents in China and passed the test carried out by the National Test Center for Polymer and Chemical Building Materials.

The product combines the corrosion resistance of plastics with the obdurability of steel and it is featured by secure and reliable ring stiffness, light weight, easy and reliable installation, good sealing performance, low transportation and construction costs, strong corrosion resistance, and strong resistance to abnormal and accidental loads. It is a kind of new environmental protection pipe heavily promoted by national and local competent departments at all levels.

As a kind of underground drainage pipe, the HDPE plastics-steel composite drain pipe with double plain wall combines the stiffness of steel with the corrosion resistance of polyethylene, so it can be widely applied to the gravity flow transportation of various corrosive and non-corrosive medium, such as municipal sewage pipe, industrial sewage pipe, rainwater drainage pipe, bridge and culvert sewage and water drainage pipe, agricultural irrigation pipe, as well as water intake pipe at the water source. It has a vast market prospect, and is the first choice of national key construction projects, so it will launch a green revolution in underground drainage pipe industry.

It executes the standard of the People’s Republic of China for urban and rural construction: CJ/T 329-2010 Spirally Wound Plastics-Steel Composite Pipes with Double Plain Wall for Underground Drainage.
