الوصف

1. It has better tensile and compressive strength: but its flexibility is not as good as other plastic pipes.

2. Low fluid resistance: The wall of PVC-U pipe is very smooth and the resistance to fluid is very small, its roughness coefficient is only 0.**9, its water transmission capacity can be increased by *0% compared with cast iron pipe of the same diameter and *0% compared with concrete pipe.

3. Good watertightness: PVC-U pipes are installed with good watertightness whether they are connected by bonding or rubber ring.

5. Bite resistant: PVC-U pipe is not a source of nutrients, so it is not subject to rodent erosion. According to the U.S. National Sanitation Foundation tests in Michigan proved that rats will not bite PVC-U pipe.

6. Performance test: Curing time Shrinkage Split strength Tensile performance Peel strength Thermal stability Application period Storage period.
