（1）. PVC material has good tensile and compressive strength
（2）. PVC material has low fluid resistance: the wall of PVC-U pipe is very smooth, and the resistance to fluid is very small, and its roughness coefficient is only 0.009.
（3）. PVC material is excellent in corrosion resistance and chemical resistance.
（4）. PVC material anti-bite: PVC-U tube is not a source of nutrients, so it will not be attacked by rodents.
