PVC-U (lead-free) drainage pipes are technologically mature drainage pipe products and are widely used in various drainage projects at home and abroad.

The product has the advantages of long life and corrosion resistance that cast iron pipes cannot match. In terms of construction, it is light in weight, easy to carry and install, and easy to connect.

It is widely used in the fields of drainage and sewage discharge of civil buildings, chemical drainage and sewage discharge, rainwater discharge, etc.

1. High safety factor

The surface hardness and tensile strength of the pipe are excellent, and the pipeline safety factor is high.

2. Small fluid resistance

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.

3. Good aging resistance

The normal service life can reach more than 50 years.

4. Small expansion coefficient

The linear expansion coefficient of the pipeline is small, which is 0.07mm/m, and the deformation is small due to temperature. The thermal conductivity and elastic modulus are small, and the anti-freezing performance is excellent compared with cast iron drainage pipes.

5. Chemical corrosion resistance

The pipeline has excellent corrosion resistance to inorganic acids, alkalis, and salts, and is suitable for industrial sewage discharge and transportation.

6. Convenient construction

Pipes and pipe fittings can be connected by bonding, which has simple construction methods, convenient operation and high installation efficiency.
