Centrifugally cast iron pipe has long been a preferred choice for a wide range of applications in various industries due to its durability, strength, and reliability. Centrifugally cast iron pipes are manufactured using a unique process that involves spinning molten iron at high speeds in a mold to create a dense and uniform structure.
One of the main advantages of centrifugally cast iron pipe is its high level of strength and durability. The manufacturing process creates a dense and homogeneous structure that is free of defects and impurities, ensuring that the pipe can withstand high pressure, temperature, and external stresses without compromising its integrity. This makes centrifugally cast iron pipes ideal for use in demanding applications such as water supply systems, sewage systems, industrial piping, and underground drainage.
In addition to its strength and durability, centrifugally cast iron pipe offers excellent corrosion resistance, making it suitable for use in environments where exposure to moisture, chemicals, or corrosive substances is a concern. The smooth internal surface of the pipe also helps to prevent the buildup of sediment, debris, and other materials that can lead to blockages and reduce the efficiency of the system. This makes centrifugally cast iron pipes easy to maintain and prolongs their service life.
Overall, centrifugally cast iron pipe is a durable, reliable, and cost-effective solution for a wide range of applications in various industries. Its high strength, corrosion resistance, versatility, and thermal conductivity make it an ideal choice for demanding projects where performance and longevity are paramount. Whether it's a residential, commercial, or industrial application, centrifugally cast iron pipe can provide the reliable performance and peace of mind that customers expect from a high-quality product.
In conclusion, centrifugally cast iron pipe offers a superior combination of strength, durability, corrosion resistance, and thermal conductivity, making it an ideal choice for a wide range of applications in various industries. With its proven performance record and long service life, centrifugally cast iron pipe is a cost-effective and reliable solution for projects where quality and reliability are of utmost importance.
Product Features
Ductile iron pipe manufacturing process:
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 is three 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 even ensuring 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, amd cpmplies with ISO8179 standard. We can also increase the zinc spraying thickness or spray zinc & aluminum alloy layer according to the customers' demand.
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.
Packing & Delivery
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 Shipping,shipment, and trucks or train for inland transport.
Can be packaged according to customer requirements

Ductile iron pipeIt is a type of cast iron, an alloy of iron, carbon and silicon. Graphite in ductile iron is in the form of spheres, and the size of general graphite is 6-7 grades. In terms of quality, the spheroidization grade of the cast pipe is required to be controlled at 1-3 grades (spheroidization rate ≥ 80%), so the mechanical properties of the material itself It has been better improved, with the essence of iron and the performance of steel. The annealed ductile iron pipe has a metallographic structure of ferrite plus a small amount of pearlite and better mechanical properties.![ISO2531 Ductile Iron Pipe]( "ISO2531 Ductile Iron Pipe")
