The pipeline friction coefficient 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. The thermal conductivity and elastic modulus are small, and the anti freezing performance is excellent compared with the cast iron drainage pipe.

The surface hardness and tensile strength of PVC pipe fittings are excellent, and the pipeline safety factor is high.

Good aging resistance, normal service life of more than 50 years.

The pipeline has excellent corrosion resistance to inorganic acid, alkali and salt, and is suitable for industrial sewage discharge and transportation.
