Advantage:
1.Sanitary: There is no heavy metal additives in PVC-U water pipe and it would not be covered with dirt or contaminated by bacterium.
2.High Flow Capacity: The smooth interior walls and low friction of PVC-U water pipe result in low flow resistance and high volume.
3.Corrosion Resistant: PVC-U water pipe is non-conductors of electricity and immune to electrochemical reactions caused by acids, based, and salts that cause corrosion in metals.
4.Low installation costs: PVC-U water pipe is lightweight and is installed with solvent cement, thread, flange, and gasket joint. Ease of installation reduces the installation costs.
5.Longevity: PVC-U water pipe can work for more than 50 years under proper use.
6.Environment-friendly: PVC-U water pipe can be recycled
