PIPES FOR NON PRESSURE UNDERGROUND DRAINAGE AND SEWERAGE APPLICATION.

DWC is an innovative product aptly described as structured wall piping system of PE/PP with smooth internal and corrugated (profiled) external surface. The corrugated (profiled) external surface of the DWC pipes gives the product excellent ring stiffness (load bearing capacity). Unlike plain pipes, DWC pipes do not deform under vehicular traffic load. Further more, since these pipes are moderately flexible, they can be aligned comfortably even in gradually bending paths.
