PVC water supply pipe fittings are designed and manufactured in accordance with national standards, products are widely used in buildings. External water supply pipeline system. The product is soft and beautiful color, inside. Outer wall is smooth, the fluid transmission resistance is small, it is 0.6-0.7 times of the same direct cast iron pipeline system. The product is light weight. Than the high strength, pressure, impact resistance, corrosion resistance is good.
