PVC drainage pipe fitting is mainly used for PVC drainage pipe connecting. PVC drainage pipe is a substitute product of traditional drainage pipes, which has better physical and chemical properties. It has a smooth inner wall and less frictional resistance than conventional drainage materials. Therefore, the installation slope of the transverse pipe is small, which can improve the indoor clear height of the building. At the same time, PVC drainage pipe fitting is lighter, one fifth of the cast iron fittings, easy to transport and operate; Adhesive connection is convenient for installation and maintenance; The price is cheaper than conventional drainage pipes, which greatly reduces the engineering cost; Strong corrosion resistance, Sewage and rainwater pipe systems are widely used.
