Compared with traditional cast iron pipe, PVC-U water supply pipe features as following:
1 Lightweight
2 Density: 1/5 or 1/6 of cast iron pipe
3 Easier carrying and operation, reduces materials and operation costs, also reduces building supports
4 Smooth inside wall, no furring, no block, flowing easier
5 Acid resistance, no rusty, no corrode treatment, service life is 4 times of casted iron pipe
6 Excellent tensile and impact strength resistance
7 Cement weld, excellent seal, suit for ground and underground installing
8 Excellent fire resistance, oxygen index is over 46
9 Excellent high temperature resistance, softening temperature over 70. C
10 Adopts special technology, can resist attacking from bacterium and biology. But they can not become bacterium and biology nutrition
11 Excellent climate resistance
12 PVC-U pipe can be affected by strong violet light. Though stimulating PVC molecule structure, PVC-U pipe surface (0.025mm only, very shallow) is affected. PVC micro molecule will become multiple organizations and compound structure forever. This makes PVC-U pipe become light yellow, but its tensile stress is stronger. If no other conditions, all above can ignore. Multiple organizations can reduce impact strength
