1. The surface hardness and tensile strength of the pipe are excellent, and the safety factor of the pipe is high.
2. Good aging resistance, normal service life can reach more than 50 years.
3. The pipeline 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 pipeline is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small.
5. The material has a high oxygen index and is self-extinguishing.
6. The coefficient of linear expansion of the pipeline is small, 0.07mm/°C, and the amount of deformation affected by temperature is small. The thermal conductivity and elastic modulus are small, and the anti-icing performance is superior to that of the cast iron drain pipe.
7. Pipe and pipe joints can be bonded, the construction method is simple, the operation is convenient, and the installation work efficiency is high.
8. Has good water tightness: PVC-U pipe installation has good water tightness regardless of bonding or rubber ring connection.
