DWC
Double Wall Corrugated Pipes
High-strength non-pressure piping for underground drainage & cable protection
Overview
DWC (Double Wall Corrugated) Pipes are high-strength non-pressure piping systems designed for underground drainage and cable protection applications.
Manufactured from HDPE, these pipes feature a corrugated outer wall for load-bearing strength and a smooth inner wall for efficient flow. They are ideal for buried installations requiring high ring stiffness and long service life.

Manufacturing Process
DWC pipes are produced using advanced co-extrusion technology:
High-grade HDPE compound is processed.
Dual-layer extrusion forms a corrugated outer wall and smooth inner wall.
Controlled cooling ensures structural stability.
Pipes are cut and socketed for jointing.
Products undergo ring stiffness and impact testing.
This ensures strength for underground applications and reliable hydraulic performance.
Advanced Manufacturing & Quality Control
Our DWC systems offer:
Each pipe is tested for ring stiffness, impact strength, and dimensional accuracy.
