PVC pipe and pipe fitting

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

PVC pipe fittings include direct connection, tee and cross joint, and the tee is divided into 45 degrees and 90 degrees.

Advantages of PVC pipe

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 little resistance to fluid. Its roughness coefficient is only 0.009. Its water transmission capacity can be 20% higher than that of cast iron pipe with the same pipe diameter and 40% higher than that of concrete pipe.

3. Excellent corrosion resistance and drug resistance: PVC-U pipe has excellent acid, alkali and corrosion resistance, is not affected by moisture and soil pH, and does not need any anti-corrosion treatment during pipe laying.

4. Good water tightness: the installation of PVC-U pipe has good water tightness whether it is connected by bonding or rubber ring.

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

6. Performance test: curing time shrinkage splitting strength tensile property peel strength thermal stability application period storage period release of harmful substances.
