1. It has good 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 has little resistance to fluid. Its roughness coefficient is only 0.009. Its water delivery capacity is 20% higher than that of cast iron pipes of the same pipe 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 damp water and soil pH. No anti-corrosion treatment is required when laying pipelines.
4. Anti-bite: PVC-U tube is not a source of nutrition, so it will not be corroded by rodents. According to a test conducted by the National Sanitation Foundation in Michigan, rats will not bite PVC-U pipes.
5. It has good water tightness: the installation of PVC-U pipes, regardless of whether it is connected by bonding or rubber ring, has good water tightness.
6. Performance test: curing time, shrinkage, splitting strength, tensile performance, peeling strength, thermal stability, pot life, storage period, release of harmful substances.
this is the whole line of the PVC pipe making machine , it include twin screw extruder machine, PVC pipe vacuum box, PVC pipe tractor, PVC pipe cutting machine, and the stacker,
