Features of N1-Type Joint Ductile Iron Pipe
1) High-velocity centrifugal casting, compact tissue, high strength and high pressure
resistance comparative to the steel tube, long useful life.
2) Low-noise.
3) Corrosion resistance, such as acid base, liquid waste, salt mist, electrification, that
surpass the steel tube.
4) Good retractility.
5) Useing N1-Type flexible joint that is adapt well to the foundations subsided and librated.
6) The joint is safe with good leak tightness.
7) The standard and design merged well(could connect with other pipes).
8) It is convenience to assemble by simple tool (spanner)
