1. The surface hardness and tensile strength of the pipe are excellent, and the pipeline safety factor is high.
2. PVC drainage pipes have good aging resistance and their normal service life can reach more than 50 years.
3. The pipeline has excellent corrosion resistance to inorganic acids, alkali and salts, and is suitable for industrial sewage discharge and transportation.
4. PVC drainage pipes have a small friction coefficient, smooth water flow, are not easy to block, and require less maintenance work.
5. PVC drainage pipe material has a high oxygen index and is self-extinguishing.
6. 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 compared with cast iron drainage pipes, they have excellent freezing resistance.
7. Bonding can be used to connect pipes and pipe fittings. The construction method is simple, the operation is convenient, and the installation efficiency is high.
