Ductile Iron Pipe (Tyton Joint or Push on Joint) Беларусь

Centrifugal casting nodular cast iron pipe is a pipe made of nodular cast iron by centrifugal spinning process. The pipeline cantransport fluid media such as water, oil and gas, and is widely used in various pipeline projects such as metallurgy,mining,water conservancy, petroleum, urban public services and so on. Ductile iron pipe has the advantages of high strength,good toughness, better than steel and good corrosion resistance. It is an ideal substitute for gray cast iron pipe and ordinary steel pipe. In addition, the produced Di pipe has good flatness, uniform wall thickness, high dimensional accuracy, good surface finish, excellent mechanical properties and firm adhesion of internal and external coatings.Flexible quick connectors and rubber gaskets are used to facilitate pipe installation. By combining the amazing ductility, high tensile strength and good corrosion resistance of nodular cast iron, this easy to operate pipe can be easily tapped, drilled or welded. Nodular cast iron pipe is famous for its practical performance, which provides unparalleled advantages for the application of water,sewage and natural gas mains!

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.

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
