1. The surface hardness and tensile strength of the pipe are excellent.
2. It has good aging resistance and a normal service life of 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 transmission.
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 property.
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 the frost resistance is excellent compared with the cast iron drainage pipe.
7. The pipes and pipe fittings can be connected by bonding. The construction method is simple, the operation is convenient, and the installation efficiency is high.
