1. Light pipes and convenient construction
The specific gravity of PVC drainage pipe is about 1.4t/m3, which is only 1/5 of that of cast iron pipe. Plastic pipes of the same length are much lighter than cast iron pipes, requiring only manual handling during installation. In addition, PVC drainage pipes use socket type adhesive joints. At the same time, their standard length (6m, 4m) is longer than that of cast iron pipes, reducing the number of joints and installation procedures.
2. Good drainage performance
The diameter of PVC drainage pipe can be smaller than that of cast iron pipe, or the same pipe diameter can use a smaller slope within the allowable scope of the specification as far as possible, so as to increase the clear height of the space, which is more beneficial to users and enhances the use function of the building.
3: Economical and beautiful
PVC drainage pipes are usually white on the outer wall, and do not need to be painted with red lead, silver powder and other anti-corrosion treatments. There is no such problem as the corrosion and peeling of the outer wall of the cast iron pipe. When they are concealed into the pipe well, they do not need frequent maintenance and care. The advantages of open installation are more obvious than the cast iron pipe: easy to clean, less harmful to visual effects, which greatly improves people's life and working environment, and also facilitates the property management of buildings.
4. Good social benefits
PVC drainage pipe can replace other steel drainage pipes in a large range, and greatly reduce the energy consumption in the steelmaking process.
5. Superior physical and chemical properties
PVC drainage pipes have stable chemical properties and unique mechanical and physical properties that enable them to be used normally for 50 years. At the same time, their corrosion resistance, aging resistance and wear resistance also enable them to be used more stably for a long time than cast iron drainage pipes and cement pipes
