The pipeline has excellent corrosion resistance to inorganic acid, alkali and salt, and is suitable for industrial sewage discharge and transmission.The construction method is simple, the operation is convenient, and the installation efficiency is high.Can maintain good water tightness.The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small. The material has high oxygen index and self extinguishing property. The linear expansion coefficient of the pipeline is small, 0.07mm/℃, and the deformation affected by temperature is small.Pvc drainage pipe has excellent corrosion resistance to inorganic acid, alkali, salt and other substances, so it is more suitable for industrial sewage discharge and transmission.Easy installation and low cost. It is easy to cut and connect. PVC glue is used for connection, which is reliable and safe
