Product Overview
About HDPE DWC Pipes
Godfill HDPE DWC (Double Wall Corrugated) pipes combine a smooth HDPE inner wall for efficient flow with a corrugated outer wall for high structural stiffness. Manufactured to IS 16098 (Part 2):2013 in SN 4 and SN 8 ring stiffness classes, these pipes are ideal for gravity sewer mains, stormwater drainage, culverts and underground cable ducting. The pipe's light weight relative to concrete and the integrated rubber-ring socket joint system dramatically reduces installation time and cost.
