PVC-U pipe has strong corrosion resistance, easy bonding, low price and hard texture. However, due to the leakage of PVC-U monomer and additives, it is only suitable for the water supply system where the conveying temperature does not exceed 45℃. Plastic piping is used for drainage, wastewater, chemicals, heating and cooling fluids, food, ultra-pure liquids, mud, gas, compressed air and vacuum system applications.

Pvc-o pipe, Chinese name biaxial oriented PVC, is the latest form of evolution of PVC pipe, through the special orientation processing technology to manufacture the pipe, the PVC-U pipe produced by extrusion method for axial stretching and radial stretching, so that the PVC long chain molecules in the pipe in the biaxial arrangement, A new PVC pipe with high strength, high toughness, high impact and fatigue resistance was obtained.

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.
