Nodular cast iron pipe manufacturer fire water supply and sewage dn400 K9 ball milled ductile iron tube
Ductile Iron Pipe
Nodular cast iron pipe refers to the pipe made by high-speed centrifugal casting with centrifugal nodular cast iron machine after using cast iron above No. 18 and adding spheroidizing agent. It is referred to as nodular pipe, nodular iron pipe and nodular cast pipe for short. It is mainly used for the transportation of tap water and is an ideal material for tap water pipeline.
Features:
it has the essence of iron, steel performance, excellent anti-corrosion performance, good ductility and easy installation. It is mainly used for water supply and gas transmission in Municipal Industrial and mining enterprises.

Detailed Photos
1.The performance of internal pressure resistance: 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 isthree times of the working pressure.
2.The performance of outer pressure resistance: The high pressure resistance can avoid the requirement of the pipe bed and protective cover, making the pipes laying rellable and economic.
3.Inner anti-corrosion layer: 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 evenensuring the drinking water transferred by the pipes get good protection.
4.Protective coating: 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, and cpmplies with ISO8179 standard. We can also increase the zinc spraying thickness or spray zinc & aluminum alloy layer according to the customers' demand.
Ductile iron pipes are available in a range of diameters from 80mm to 1600mm and are suitable for both potable water transmission
and distribution (in accordance with BS EN 545) and sewerage (in accordance with BS EN 598).Ductile iron pipes are simple to joint, can be laid in all weather conditions and often without the need for selected backfill. Its high safety factor and ability to accommodate ground movement make it the ideal pipeline material for a wide range of applications.
production line & test
The production of our Ductile iron pipes is tightly regulated and all of the pipes we produced have been fully tested to international standards to ensure we only supply the hightest products.
Application
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.
Packaging & Shipping
DN80-DN300: Usually by bundles;
DN350-DN2000: Usually by bulk;
During transportation, the pipes are fixed by timbers, blocks, nails & steel ropes with cushions at the side in possible moving
directions;
Bulk or containers for shipment, and trucks or train for inland transport.
