Ductile Iron Water Pipe

Product Parameter
Product Show
Ductile iron water pipes are a versatile and durable option for water distribution systems. These pipes are made from a specific type of cast iron that has been treated with magnesium to give it enhanced flexibility and strength. This unique composition makes ductile iron pipes well-suited for transporting water in various environments and under different pressure conditions.
One of the key advantages of ductile iron water pipes is their exceptional strength. Unlike traditional cast iron pipes, ductile iron pipes have a higher tensile strength, making them better able to withstand the pressure of flowing water and resist cracking or breaking under stress. This durability makes them a reliable choice for both above-ground and underground water distribution systems.
In addition to their strength, ductile iron water pipes also offer excellent corrosion resistance. The magnesium treatment of the iron gives these pipes a protective layer that helps to prevent the formation of rust and corrosion, even when exposed to harsh environmental conditions. This corrosion resistance prolongs the lifespan of ductile iron pipes and reduces the need for frequent maintenance or replacements.
Another benefit of ductile iron water pipes is their flexibility. The magnesium treatment allows the iron to deform slightly under pressure without breaking, making these pipes more forgiving of ground movement or shifting soil conditions. This flexibility also makes ductile iron pipes easier to install than rigid materials, reducing the possibility of damage during the construction process.
Overall, ductile iron water pipes offer a reliable and long-lasting solution for water distribution systems. Their strength, corrosion resistance, flexibility, and smooth surface make them well-suited for a range of applications, from municipal water mains to industrial process piping. With proper installation and maintenance, ductile iron pipes can provide years of trouble-free service and help to ensure the reliable delivery of clean water to homes, businesses, and communities.
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.
