HDPE Pipes SDR 21 Size 90 inch Thickness 4.3 mm Black

These high-density polyethylene (HDPE) pipes are engineered to deliver long-lasting performance in the most demanding environments found across Oman, from the coastal humidity of Muscat to the arid heat of the interior. Manufactured from premium-grade polyethylene, they provide exceptional resistance to corrosion, chemicals, and impact, ensuring a reliable and leak-free service life.

With a standard dimension ratio of SDR 21, a 90 mm outside diameter, and a 4.3 mm wall thickness, these pipes offer a robust balance of strength and flexibility. They are designed to withstand high operating pressures and elevated temperatures, while their black coloration provides inherent protection against ultraviolet radiation, making them suitable for prolonged outdoor exposure under the Omani sun.

These pipes are non-conductive and feature a smooth internal surface that minimizes friction and reduces energy consumption in fluid transport. Their lightweight nature simplifies handling and installation, and they can be securely joined using electric welding (electrofusion) or butt fusion techniques, ensuring a seamless and durable piping system.
