Factory Best Price 500mm K9 C40 6 Meter Long DI Pipe Ductile Iron Pipe for Water Supply
Product Detail
Nodular cast iron (or ductile iron) pipes offers the strength of steel and the toughness of iron. Graphite is spheroidized (grades 6–7) with a spheroidization degree of 1–3 and rate ≥80% and as a consequence the mechanical properties are improved. The microstructure after annealing is mainly ferrite with a small amount of pearlite, which has good ductility and strength.

1.Ductile Iron Pipes: The Difference is in the Manufacture, the Advantages in the Performance
2.Internal Pressure Resistance: High working pressure with a burst pressure of three times the working pressure, providing excellent safety.
3.Resistance to external pressure: The solid external resistance allows installation reliability and economic without using special bedding or encasement materials.
4.Inner Anti-Corrosion Layer: Centrifugal cement mortar lining (ISO 4179) provides a friction reduction and a long-lasting protection, making drinking water safe.
5.Protective Coating: Zinc spraying (≥130 g/m 2 , ISO 8179) combined with chlorinated resin paint offers better corrosion protection. Optional thicker zinc or zinc-aluminium coating are possible, according to the customer demand.
Features
Ductile Iron pipes are cast iron pipes which have been alloyed to include the strength of steel with the toughness of iron.
Spheroidization is regulated (rate ≥80%) in the levels 1–3 to improve the mechanical properties. Annealed pipes have a ferrite matrix with a small amount of pearlite and they provide very good resistance to corrosion, high plasticity, sealing and ease of use.
Microstructure Spherical Graphite There is a distribution of spherical graphite in the ferrite-pearlite matrix. The Pearlite content is different by size: for small pipes ≤20%, for large pipes ~25%. This enables them to be used for the safe and efficient transport of water, gas, and oil in urban and industrial applications.
Application
The ductile iron pipes with diameter ranging from 80 to 1600 mm are applicable to drinking water (BS EN 545) and sewage (BS EN 598) system. They are simple to connect, can be laid in any weather often without any special backfill and provide a high safety factor with flexibility for ground movement, making them the best choice for a wide variety of pipeline applications.
