Characteristics of PVC drainage pipes

Characteristics of PVC drainage pipes

1. PVC drainage pipes have good surface hardness and tensile strength, so we say their pipeline safety system is very high.

2. The aging resistance of PVC drainage pipe is also very good. If it is used normally, its service life can reach more than 50 years.

3. PVC drainage pipes have excellent corrosion resistance to inorganic acids, alkalis, and salts, making them more suitable for the discharge and transportation of industrial wastewater.

4. The friction coefficient of PVC drainage pipes is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small.

5. PVC drainage pipe material has a high oxygen index and good self extinguishing performance.

6. The expansion coefficient of PVC drainage pipes is small, at 0.07mm/℃, with little deformation due to temperature influence, and low thermal conductivity and elastic modulus. Compared with cast iron drainage pipes, their frost resistance is also quite good.

7. The connection between PVC drainage pipes and fittings can be bonded, and the construction method is simple and the operation is quite convenient. Natural installation efficiency will be very high.

8. PVC drainage pipes also have good water tightness because the installation of PVC-U pipes, whether connected by adhesive or rubber rings, has good water tightness.
