Centrifugally Cast Ductile Iron Pipe is a kind of pipe made from spherical graphite cast iron by centrifugal spinning process. The pipes, which can convey many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility.

Centrifugal ductile iron has the essence of iron and the performance of steel, so the ductile iron pipes have excellent security performance than pipes made from other materials. The designed working pressure is much higher than that of pipes made from other materials, the safty factor is pretty high, and the possible burst pressure is three times of the working pressure.

The high pressure resistance can avoid the requirement of the pipe bed and protective cover, making the pipes laying rellable and economic.

The inner layer of ductile iron pipes are centrifugally sprayed with cement mortar. Cement lining complies with the international standard ISO4179, ensuring the mortar strong and smooth. The motor coating will not fall off or foul, and its thickness is even ensuring the drinking water transferred by the pipes get good protection.

The zinc spraying of ductile iron pipes could protect the pipes proactively through the electrochemical effect of zinc and iron. With the high chiorinated resin paint, the pipes will get enhanced anti-corrosion protection. The surface zinc spraying of each pipe is not less than 130g/m², amd cpmplies with ISO8179 standard. We can also increase the zinc spraying thickness or spray zinc & aluminum alloy layer according to the customers' demand.

1.Ductile iron pipes for water conveyance: Product standards: BS EN545:2002, ISO2531:1998 1) Pipes are supplied in standard length of 5.5/6.0m, short length pipes as per respective standards can be supplied. 2) In addition to Class K9 pipes, we also supply K7, K8, K10 and K12 classes of pipe. 3) The thickness can be determined by the formula e=K (0.5+0.001DN) 4) PFA (allowable operating pressure) is the internal pressure, exclusive of surge, that a component can safely withstand in permanent service. 5) PMA (allowable maximum operating pressure) is the maximum internal pressure, including surge, that a component can withstand for a relatively short duration, when either fixed above ground level or laid and back filled underground in order to measure the integrity and leak tightness of the pipek. 2. Ductile iron pipes for sewerage application: Product standard: BS EN598:2002 Quality checks at every stage of manufacturing: 1) Strict selection of raw material is an indispensable requirement to produce quality ductile iron pipes and fittings. 2) We produces liquid metal suited to manufacture ductile iron pipes. The liquid metal is further processed in induction furnaces. It is then treated with magnesium for modularization and transferred to the centrifugal spun casting machines. 3) The pipes are heat treated, zinc coated, hydrostatically tested, tested, cement mortar lined and finished with a layer of bitumen coating. 4) The in process inspection and quality control at all points during the production cycle is strictly maintained and documented as ISO9001 quality systems.
