Flanged Ductile Iron Pipe

Flanged ductile iron pipe is a popular choice in the construction and infrastructure industries due to its durability, strength, and versatility. This type of pipe is made from ductile iron, a type of cast iron that has been treated with magnesium to make it more flexible and resilient. The addition of magnesium gives the pipe its ductile properties, which allow it to withstand high levels of pressure and stress without breaking or bending.

One of the key features of flanged ductile iron pipe is its flanged ends, which are designed to allow for easy and secure connections between pipe sections. The flanges are flat, circular discs that are attached to the ends of the pipe and have holes that line up with matching holes on another pipe or fitting. Bolts are then used to secure the flanges together, creating a tight and leak-proof connection.

Flanged ductile iron pipe comes in a wide range of sizes, from small diameters used for residential plumbing to large diameters used for municipal water and sewer systems. The thickness of the pipe walls can also vary, depending on the intended use and the pressure requirements of the application. Additionally, the pipe can be coated with various materials, such as epoxy or polyurethane, to protect it from corrosion and extend its lifespan.

Another benefit of flanged ductile iron pipe is its resistance to corrosion. The protective coatings applied to the pipe prevent rust and deterioration, making it ideal for use in underground or outdoor applications where exposure to moisture and chemicals is common. This resistance to corrosion helps to extend the lifespan of the pipe and reduce maintenance costs over time.

Overall, flanged ductile iron pipe is a versatile and reliable option for a wide range of applications in the construction and infrastructure industries. Its strength, durability, and resistance to corrosion make it an excellent choice for water and sewer systems, irrigation, and other utility applications. With proper installation and maintenance, flanged ductile iron pipe can provide years of reliable service, making it a cost-effective and practical solution for any project.

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.

Ductile iron pipe manufacturing process:

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.

• 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
