Advantages of pvc drainage pipe products:
1. The surface hardness and tensile strength of the pipe are excellent, and the safety factor of the pipeline is high.
2. Good aging resistance, and the normal service life can reach more than 50 years.
3. The pipeline has excellent corrosion resistance to inorganic acid, alkali and salt, and is suitable for industrial sewage discharge and transportation.
4. 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.
5. The material has high oxygen index and self-extinguishing.
6. The linear expansion coefficient of the pipeline is small, which is 0.07mm/℃, and the deformation is small under the influence of temperature. The thermal conductivity and elastic modulus are small, and the frost resistance is better than that of cast iron drainage pipes.
7. Pipes and pipe fittings can be connected by bonding, with simple construction method, convenient operation and high installation efficiency.
