The total assets of CNBM Group exceeded USD 40 billion and ranked 270th of GLOBALFORTUNE500 Corporations in 2015.

Ductile Iron Pipe, a product of advanced metallurgy, offers unique properties for conveying portable/sewage water under pressure. It combines

the physical strength of mild steel and long life of gray cast iron, and has been widely adopted in worldwide range.

Through years of efforts, CNBM Water System Division has grown into a leading solution provider of ductile iron pipe and fittings in China.

Specifications

Standard Wall Thickness

• Nominal wall thickness of pipes: e=K (0.5+0.001*DN)
• Where, DN: Nominal diameter; K: Coefficient (K=7, 8, 9, 10, 11, 12…)
• Nominal wall thickness of pipe fittings: e=7+0.014*DN (K=14) e=6+0.012*DN (K=12)
• Nominal iron wall thickness ≤ 6, the limit deviation on the nominal wall thickness is -1.3
• Nominal iron wall thickness > 6, the limit deviation on the nominal wall thickness is – (1.3+ 0.001DN)
