잡담
1. Has good tensile and compressive strength: but its flexibility is not as good as other plastic pipes.
2. Small fluid resistance: The pipe wall of PVC-U pipe is very smooth, and the resistance to fluid is very small. Its roughness coefficient is only 0.009. Its water transport capacity can be increased by 20% compared with cast iron pipes of the same diameter and 40% higher than that of concrete pipes. %.
3. Excellent corrosion resistance and chemical resistance: PVC-U pipes have excellent acid resistance, alkali resistance and corrosion resistance, and are not affected by moisture and soil pH, and do not need any anti-corrosion treatment when laying pipes.
4. Good water tightness: The installation of PVC-U pipes has good water tightness whether it is connected by bonding or rubber ring.
5. Anti-bite and rodent: PVC-U pipe is not a source of nutrition, so it will not be eroded by rodents. According to the test conducted by the National Sanitation Foundation in Michigan, rats will not bite PVC-U pipes.
