Kingbull's PVC-U pipes have excellent physical and chemical properties, high impact resistance, small fluid resistance, 30% higher of flow than cast iron pipe of the same caliber and also have high aging resistance. The pipes have excellent corrosion resistance to inorganic acids, alkali, salts and are suitable for industrial sewage discharge and transport. With small friction coefficient, smooth flow, less clogging, the pipes require less maintenance. The pipes have a small linear expansion coefficient, 0.07 mm/m, has little deformation under the impact of temperature. The thermal conductivity and modulus of elasticity are also small, and the anti-freezing property is excellent as compared with cast iron drainage pipes. Pipes and fittings can be bonded together, which is simple in construction and easy to operate, thus effectively accelerating the progress of the project and reducing the construction cost. In terms of saving construction cost, use of PVC-U pipes and fittings is cheaper than the total cost of using cast iron pipe system of the same specifications. The materials have high oxygen index and are self-extinguishing. Our products are mainly white in color, which is bright and smooth.
