UPVC Pipes Sewage/Drainage System National Size 140 mm Thickness 3.5 mm Gray Colour

These UPVC pipes from National Plastic Factory are the reliable choice for sewage and drainage systems across Qatar. With a 140 mm outer diameter and a minimum wall thickness of 3.5 mm, they deliver robust performance for both above-ground and underground installations, whether inside or outside buildings.

Engineered for non-pressure water networks, these pipes offer a smooth internal surface that minimizes friction, ensuring efficient flow. Their lightweight nature simplifies handling, installation, and maintenance—an advantage in fast-paced construction projects in Doha, Al Rayyan, and Al Wakrah.

Built to withstand Qatar's demanding environment, these pipes resist corrosion from acids, salts, oils, alkalis, and moisture, as well as offering chemical, weather, and fire resistance. This durability ensures long service life in both residential and commercial applications.
