HDPE double wall corrugated pipe for driange and sewage DN110-1200mm, ring stiffness class SN4-SN10
HDPE double wall corrugated (DWC) pipe for drainage and sewerage is a new type of pipe for outdoor drainage of building and municipal sewage. DWC pipe has smooth interior wall and corrugated exterior,offers exceptional hydraulics and strength,also provides superior corrosion and abrasion resistance.This make it an excellent alternative to reinforced concrete(RCP) and corrugated metal pipe(CMP)

> Structurally designed corrugated exterior to support typical construction and longterm loading;
> Smooth interior with a low Manning's value of 0.012 resulting in increased flow capacity;
> Inert HDPE material is resistant to the effects of chemicals,abrasion,hot soils and effluent;
> Light weight product for best-installed cost and maximizing delivery and installation efficiencies;
> Long service life,up to 50 years;
> Socket connection,easy installation.
