HDPE Corrugated Sewer Pipes in Saudi Arabia

Overview

Twin-wall corrugated pipes are the modern generation of drainage: a corrugated outer wall giving high ring stiffness, and a smooth inner wall that improves flow and prevents sedimentation — at a fraction of the weight of concrete. We produce them in SN4, SN8 and SN16 stiffness classes, testing ring stiffness and flexibility on every batch.

Frequently Asked Questions

What is the difference between SN4 and SN8?+

SN denotes ring stiffness — SN8 suits deeper burial and higher loads (under roads), SN4 suits moderate depths. We help you specify by burial depth and site loads.

Do you produce compatible inspection chambers?+

Yes — we manufacture polyethylene chambers and manholes compatible with the same pipes; see the Inspection Chambers & Manholes page.
