HDPE Polyethylene Plastic Pipe PN 3.9 Bar [PE 63] Outside Diameter 400 mm SDR 21 Color Black | Almona Factory

This HDPE (high-density polyethylene) pipe, manufactured by Al-Mona Factory, is engineered for reliable liquid conveyance in demanding environments. With a 400 mm outside diameter and a pressure rating of 3.9 bar (SDR 21), it meets the rigorous requirements of modern infrastructure projects across Qatar, from Doha's urban developments to agricultural schemes in Al Rayyan and Al Wakrah.

Constructed from PE 63 grade material, this pipe offers exceptional resistance to corrosion, chemicals, and external impact, ensuring a service life of over 50 years with minimal maintenance. Its smooth inner surface reduces friction, optimizing flow efficiency and reducing energy costs—a key advantage in Qatar's arid climate where water conservation is paramount.
