PVC drainage pipe surface hardness and tensile strength, pipeline safety factor is high; PVC drainage pipe anti-aging good, normal long life, up to 50 years; pipe on the inorganic acid, alkali, salt corrosion resistance , For industrial wastewater discharge and transportation; PVC drainage pipe friction coefficient is small, smooth flow, not easy to plug, less maintenance work; material oxygen index is high, with self-extinguishing; PVC drainage pipe line expansion coefficient is small, by the temperature The impact of small deformation. Thermal conductivity and elastic modulus is small, compared with cast iron drainage pipe anti-frozen performance; pipe, pipe fittings can be used to connect, simple construction method, easy to operate, high efficiency.
