PVC-U pipe

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

b)High strength: tensile strength comes to above 45MPa.

c)Less resistance: wall of the inner layer is smooth, prevents scum buildup. The water pressure and discharge of PVC-U pipe is 30% lower than cast pipes in the same diameter, and it can save the cost of discharge power.

d)Corrosion resistance: it has the excellent resistance to the corrosion caused by acid, alkaline, chemical and electricity. Stains will not occur.

e)Simple installation: connect easily with rubber rings. It is easy to carry out and seals well.

f)Long lifespan: under the normal working pressure, the lifespan reaches to 50 years.

g)    Sanitary and non-toxic: it accords with the drinking water standard; the water is conveyed without secondary pollution.

h)Low cost: with lower cost of installation, transportation and raw material, the total cost of the whole engineering makes the cost 30% lower than cast pipes.
