Charateristics of PVC Pipe:      Light and convenient to transport, load and unload: PVC pipes are light. The density is 1/5 of the iron pipe’s, so it is convenient to transport load and unload the PVC pipes. Furthermore, the cost of installation will decrease.      Excellent resistance to chemical substances: PVC pipes are acid-proof alkali-proof and corrosion-proof. They are suitable for the chemical industry.      Low fluid resistance: The inner layer of the PVC pipe is smooth and has low fluid resistance. Its coefficient of friction is only 0.009, which is lower than any other pipes. PVC pipes can be brought down 1-2 grades in the same flow of other pipes.      Great mechanical strength: PVC pipes can resist the pressure of water, the outer pressure and the impact. They are suitable to piping project under different condition.          Good insulation of electricity: PVC pipes have good insulation of electricity. They are suitable to be used as the pipes of electric wire and cable, and as the pipes of wire in the construction industry.       No effects on the water quality: The dissolving experiment demonstrates that PVC pipes have no effect on the Water quality. PVC pipes are the best pipes as the tap-water pipes currently.            Easy installation: Movalbe PVC pipes can be cased and joined each other. The fat-socket pipes can be joined each other with glue. It’s easy to install the PVC pipes quickly, so that to low down the installation cost .
