Self-Restraining Ductile Iron Pipe

Introducing the innovative Self-restraining Ductile Iron Pipe, a revolutionary product that is changing the way we think about pipe systems. This versatile and durable pipe is designed to provide maximum strength and stability, while also offering the convenience of self-restraining features that eliminate the need for additional restraint systems.

Made from high-quality ductile iron, this pipe is built to withstand the toughest conditions and provide reliable performance for years to come. The unique design of the self-restraining ductile iron pipe allows it to expand and contract with changes in temperature, making it ideal for a wide range of applications, including water distribution, sewer systems, and industrial piping.

One of the key features of the self-restraining ductile iron pipe is its ability to eliminate the need for external restraint systems. Traditional pipe systems often require additional support structures or restraint systems to prevent movement and ensure stability. However, with the self-restraining ductile iron pipe, these systems are no longer necessary, saving time and money on installation and maintenance.

When it comes to quality and reliability, the self-restraining ductile iron pipe stands out as a superior choice. This pipe is manufactured to strict industry standards and undergoes rigorous testing to ensure durability and performance. With a proven track record of success in a variety of applications, you can trust the self-restraining ductile iron pipe to deliver exceptional results every time.

In conclusion, the self-restraining ductile iron pipe is a game-changer in the world of pipe systems. With its innovative design, self-restraining capabilities, and durable construction, this pipe offers unmatched strength, stability, and performance for a wide range of applications. Trust the self-restraining ductile iron pipe for all your piping needs and experience the difference in quality and reliability.

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
