Products Description
HDPE Double Wall Corrugated Pipe Plastic Drain Pipe Culvert tube
HDPE Double Wall Corrugated Sewage Pipe is made of high density polyethylene, which is co-extruded by inner and outer extruders respectively and formed in one step. The inner wall is flat and smooth, and the outer wall is corrugated. It has an annular outer wall with a hollow layer between the inner and outer walls. It has unique structure and high strength.The whole production process is: extrusion-compounding-molding-cooling-cutting-finished product.

Our Advantages
1.
It has the characteristics of light weight, high ring stiffness, convenient construction,transportation and installation,low installation cost, high ultraviolet resistance stability and good flexibility etc.Compared with other pipes in same diameter,the flow rate of HDPE double-wall corrugated pipe is higher because of its smooth inner wall.
2.
HDPE double-wall corrugated pipe adopts annular structure wall pipe and optimized corrugated structure, so that the pipe has greater strength and appropriate flexibility per unit weight, which makes the raw material more efficient.
3.
Reliable connection to prevent leakage:HDPE double-wall corrugated pipe adopts reinforced design in socket and it is connected with sealing rubber ring which makes the pipe more firm and reliable before and after connection.And the strict control of the size of the socket joint makes the installation more convenient and leakage prevention more effective.
4.
Implement the standard "Buried Polyethylene (PE) Structural Piping System Part I: Polyethylene Double Wall Corrugated Pipe"
GB/T19472.1-2004
