PVCU pipes for water supply

Performance of PVC-U water supply pipes

1. Lightweight, easy to transport, low construction intensity, fast progress, and can save construction costs

The density of PVC-U pipes is about 1400kg/m3, which is only 1/5 of cast iron pipes and 1/3 of concrete pipes. Compared with traditional pipes, the construction cost can be reduced by 30% -50%

2. Low fluid resistance

The wall of PVC-U pipes is very smooth and has little resistance to fluids. Its roughness coefficient is only 0.009, and its water transport capacity can be increased by 20% compared to cast iron pipes of the same diameter and 40% compared to concrete pipes

3. Excellent corrosion resistance and chemical resistance

PVC-U pipes have excellent acid, alkali, and corrosion resistance, and are not affected by moisture and soil acidity or alkalinity. No anti-corrosion treatment is required during pipeline laying

4. Based on actual engineering experience, maintenance costs are low

PVC-U pipe maintenance is simple and does not require expensive costs or complex tools. Based on actual engineering experience, its maintenance cost is only 30% of that of cast iron or concrete pipes

5. It has good water tightness

The installation of PVC-U pipes, whether using adhesive or rubber ring connections, has good water tightness

6. Anti biting

PVC-U pipes are not a source of nutrients, so they are not susceptible to rodent erosion According to experiments conducted by the National Health Foundation in Michigan, mice do not bite PVC-U pipes

7. The material is hygienic and does not pollute the water quality

PVC-U pipes do not scale and will not cause secondary pollution to water quality during water transportation

8. Long lifespan

The designed service life is over 50 years. It is reported that a PVC-U water pipeline buried in the UK in 1939 is still intact today
