HDPE /PP Double Wall Corrugated Pipe (ID100-600mm)

HDPE / PP Double Wall Corrugated Pipe (ID100-600mm)

 

 

Double Wall Corrugated Pipe: Double wall pipe section. The inner walls are smooth and flat. While the outer wall is bumpy. Nominal Diameter (DN): The nominal diameter of the pipe, which is divided into two series: the inner diameter series (ID) and the outer diameter (OD) series. Ring Stiffness (SN): A measure of the ability of a pipe to resist circular deformation. Unit units: kN / m2. In the 1980s, the German company produced the world's first Double Wall Corrugated pipe used in underground sewage systems.

 

The advantages of HDPE double wall corrugated pipes
