The advantages of PVC water pipes:
1. has good tensile strength, compressive strength: but its flexibility is not as good as other plastic pipes.
2. The fluid resistance is small: the wall of the PVC-U pipe is very smooth, the resistance to the fluid is very small, its roughness coefficient is only 0.009, its water delivery capacity is 20% higher than the same diameter of cast iron pipe, 40% higher than the concrete pipe.
3. Corrosion resistance, drug resistance is good: PVC-U pipe has excellent acid resistance, alkali resistance, corrosion resistance, not affected by moisture and soil pH, pipeline laying without any anti-corrosion treatment.
4. Have good water tightness: PVC-U pipe installation, whether the use of bonding or rubber ring connection, have good water tightness.
