ERA PVC PN16 Pipe Fittings Skew Tee With DVGW Certificate elbow dimensionsn1. It has good tensile and compressive strength: but its flexibility is not as good as other plastic pipes.n2. 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. %.n3. 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.n4. Good water tightness: The installation of PVC-U pipes, regardless of whether they are connected by bonding or rubber rings, has good water tightness.n5. Anti-gnawing: PVC-U pipe is not a nutrient source, so it will not be eroded by rodents. According to tests conducted by the American Sanitation Foundation in Michigan, rats will not bite PVCU pipes.n6. Performance test: Curing time, shrinkage rate, splitting strength, tensile properties, peel strength, thermal stability, applicable period, release of harmful substances during storage period.n
