GB PVC DWV PIPE
1. The surface hardness and tensile strength of pipes are excellent, and the safety factor of pipes is high.
2. It has good aging resistance and normal service life of 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. Pipeline friction coefficient is small, water flow is smooth, blockage is not easy and maintenance workload is small.
5. The material has high oxygen index and self-extinguishing property.
6. The coefficient of linear expansion of pipeline is small, 0.07 mm/ C, and the deformation affected by temperature is small. The thermal conductivity and modulus of elasticity are small, and the frost resistance of cast iron drainage pipe is better than that of cast iron drainage pipe.
7. Pipe and fittings can be joined by bonding. The construction method is simple, the operation is convenient and the installation efficiency is high.
8. Good water tightness: The installation of PVC-U pipes has good water tightness, regardless of the use of bonding or rubber ring connection.
