1. The surface tensile strength and hardness of the pipe are excellent, and the safety factor of the pipe is relatively high.
2. The anti-aging performance is good, and the service life of normal PVC drainage pipes can reach more than 50 years.
3. The pipeline has excellent corrosion resistance to inorganic acid, alkali and salt, so it is suitable for the transportation and discharge of industrial sewage.
4. The internal friction coefficient of the pipeline is small, the water flow is smooth, the blockage is not easy to occur, and the maintenance workload is small.
5. The oxygen index in the material is high, and the pipeline is self extinguishing.
6. The expansion coefficient of the pipeline is small, normally 0.07mm/℃, and the deformation is small due to temperature. At the same time, its thermal conductivity and elastic modulus are also small, and its frost resistance is better than that of cast iron drain pipes.
7. The connection between pipes and pipe fittings can be made by bonding, which is simple in construction, convenient in operation and efficient in installation.
8. Whether the PVC-U pipe is installed by bonding or rubber ring connection, the pipe has good water tightness.
