PVC-U has high tensile strength, and high shock strength. The piping network of PVC-U is not easy to break, and it works safety.

The piping network with normal material can be used around 20 to 30 years, but the PVC-U piping network can be used longer than 50 years.

The price of PVC-U piping network are cheaper than that of cast iron.

The inside and outside wall are smooth, the coefficient of friction is small, roughness is only 0.008 to 0.009, anti-fouling property is strong, fluid transport efficiency is enhanced 25% than cast iron piping network.

PVC-U material has strong resistance to most of acid and alkali. No rust, no antiseptic treatment. The service life is 4 times than that of cast iron.

Weight is very light. The density of PVC-U is only 1/5 to 1/6 of that of cast iron. The method of connection is very simple, and the process of installation is very quickly.
