1. The surface hardness and tensile strength of the pipe are excellent, and the safety factor of the pipe is high.
2. Good anti-aging performance, the normal service life can reach more than 50 years.
3. The pipe has excellent corrosion resistance to inorganic acids, alkalis and salts, and is suitable for industrial sewage discharge and transportation.
4. The friction coefficient of the pipe is small, the water flow is smooth, it is not easy to be blocked, and the maintenance workload is small.
5. The material has a high oxygen index and is self-extinguishing.
6. The linear expansion coefficient of the pipe is small, which is 0.07mm/℃, and the deformation is small due to temperature. The thermal conductivity and elastic modulus are small, and the anti-freezing performance is excellent compared with cast iron drainage pipes.
7. The connection of pipes and pipe fittings can be bonded, the construction method is simple, the operation is convenient, and the installation efficiency is high.
8. Good watertightness: The installation of PVC-U pipes has good watertightness regardless of whether it is bonded or connected with rubber rings.
