JWELL Machinery PVC Pipe Extrusion Machine

Advantages of pipes

1. It 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 has very little resistance to fluid. Its roughness coefficient is only 0.009. Its water delivery capacity can be 20% higher than that of 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, corrosion resistance, and are not affected by moisture and soil pH. No anti-corrosion treatment is required when laying pipes.

4. Good water tightness: PVC-U pipes have good water tightness regardless of whether they are connected by bonding or rubber rings.

5.  Anti-gnawing: PVC-U pipe is not a nutrient source, so it will not be eroded by rodents. According to tests conducted by the National Sanitation Foundation in Michigan, rats will not bite PVC-U pipes.

6. Performance test: curing time, shrinkage rate, splitting strength, tensile properties, peel strength, thermal stability, potency period, storage period, release of harmful substances.
