Advantages of PVC drainage pipe：

1. Light pipe and convenient construction

The proportion of PVC drainage pipe is about 1.4t/m3, only for cast iron pipe l / 5, the same length of plastic pipe is much lighter than cast iron pipe, installation only manual handling, and PVC drainage pipe is a socket type dissolving interface, at the same time, its standard length (6m, 4m) than cast iron pipe long, reduce the number of interfaces, reduce the installation process.

2, good drainage performance

The pipe diameter of PVC drainage pipe can be smaller than that of cast iron pipe, or the same pipe diameter can be used as far as possible within the scope of the specification permits, which can increase the net height of the space, more favorable for users, and enhance the use of the function of the building.

3: economic, beautiful

PVC drainage pipe usually outer wall is white, and is not used as paint brush red lead, silver powder and other anti-corrosion treatment, there is no such as cast iron pipe outer wall corrosion and fall off and other problems, hidden into the pipe well does not need frequent maintenance care, open installation is more significant than cast iron pipe advantages: Easy to clean, less obstruction to visual effects, greatly improve people's living, working environment, but also convenient building property management.

4. Good social benefits

PVC drainage pipe can be widely replaced by other steel drainage pipe, and greatly reduce the energy consumption in the process of steel making.

5. Excellent physical and chemical properties

PVC drainage pipe chemical properties are stable, unique mechanical and physical properties make it can be used normally for 50 years, at the same time, its corrosion resistance, aging resistance, wear resistance also make it more stable than drainage cast iron pipe, cement pipe long-term use.
