2)  plastic Union CPVC Union  UPVC Union advantages

1.Light weight: weight in unit length is only 1/6 of the cast iron pipes.

2.High strength: tensile strength comes to above 45 Map.

3.Low resistance: the inner layer wall is smooth and prevents scum buildup. The water pressure and discharge of PVC-U pipe is 30% lower than cast iron pipes with the same diameter and can save the cost of discharge power.

4.Corrosion resistance: excellent resistance to corrosion that is caused by acids, alkaline, chemicals and electricity, therefore causing no stains.

5.Easy installation: connects easily with rubber rings. It is easy to install and seals well.

6.Long lifespan: under normal conditions the lifespan can reach up to 50 years.

7.Low cost: with lower cost of installation. Transportation and raw materials, the total cost of the engineering makes PVC-U 30% lower than that of cast iron pipes.
