UPVC Pipes Nominal Pressure 13.8 Bar Size 4 inch Thickness 5.4 mm Gray

These gray UPVC pipes are engineered for demanding water systems in Qatar's building and industrial sectors. With a nominal pressure of 13.8 bar, a 4-inch diameter, and a 5.4 mm wall thickness (SDR 21), they deliver consistent performance in cold potable water and high-pressure networks—whether installed above ground or buried beneath the Qatari terrain.

Made from durable unplasticized polyvinyl chloride, these pipes resist corrosion from acids, salts, oils, alkalis, and moisture—making them ideal for Qatar's coastal and humid environment. Their lightweight nature simplifies transport and installation across Doha, Al Rayyan, and Al Wakrah, while their smooth interior ensures hygienic water flow and minimal pressure loss.
