What are the advantages and disadvantages of pvc pipes?

PVC plumbing advantage 

1. With better anti-pull, anti-pressure strength: but its flexibility is not as good as other plastic tubes.

2. Fluid resistance is small: PVC-U pipe wall is very smooth, the resistance to the fluid is very small, its rough coefficient is only 0.009, its water transmission capacity can be compared with the same diameter cast iron pipe increased by 20%, than the concrete pipe 40%.

3. Corrosion-resistant, drug-resistant: PVC-U pipe with excellent acid resistance, alkali resistance, corrosion resistance, not affected by moisture and soil acidity, pipe laying without any anti-corrosion treatment.

4. Has good water tightness: PVC-U pipe installation, whether using bonding or rubber ring connection, have good water tightness.

5. Anti-bite rodent: PVC-U tube is not a source of nutrition, so it will not be eroded by rodents. According to tests conducted by the National Health Foundation in Michigan, mice do not bite PVC-U tubes.

The disadvantages of pvc pipes

Pvc pipes are less flexible than other plastic pipes. Thermal stability and impact resistance are poor, whether it is hard or soft PVC in the process of easy to produce brittleness. It is harmful to the human body.
