Ductile Iron Pipe, commonly referred to as DI Pipe, is a versatile and durable material used in a wide range of industries for various applications. DI Pipe is made from ductile iron, a type of cast iron that is more flexible and impact-resistant than traditional cast iron. This makes DI Pipe an ideal choice for transporting water, sewage, and other fluids in municipal, industrial, and agricultural settings.
One of the key characteristics of DI Pipe is its high tensile strength, which allows it to withstand high pressure and impact without fracturing or breaking. This makes DI Pipe suitable for underground and above-ground applications where strength and durability are essential. DI Pipe is also corrosion-resistant, which prolongs its lifespan and reduces maintenance costs over time.
In addition to its strength and durability, DI Pipe is also known for its ease of installation. The pipe is lightweight compared to other materials such as steel or concrete, making it easier to transport, handle, and install. DI Pipe can be easily cut and joined using mechanical or push-on joints, further simplifying the installation process. This ease of installation not only saves time and labor costs but also reduces the risk of errors and delays during construction.
DI Pipe is also a cost-effective choice for water and wastewater infrastructure projects. The material itself is relatively inexpensive compared to alternatives such as steel or concrete, and its long lifespan reduces the need for frequent repairs or replacements. In addition, the smooth interior surface of DI Pipe allows for efficient flow and reduces friction losses, which can result in lower energy consumption and operating costs over time.
DI Pipe is also environmentally friendly, as it is made from recycled materials and is fully recyclable at the end of its lifespan. This makes it a sustainable choice for infrastructure projects and aligns with modern environmental regulations and standards. Furthermore, DI Pipe is a safe and reliable choice for transporting potable water, as it is free from harmful chemicals or compounds that can leach into the water supply.
In conclusion, DI Pipe is a versatile, durable, and cost-effective material that is suitable for a wide range of applications in various industries. Its strength, durability, ease of installation, and cost-effectiveness make it a popular choice for water and wastewater infrastructure projects. Whether for residential plumbing, municipal water distribution, or industrial sewage conveyance, DI Pipe provides a reliable and efficient solution for transporting fluids. Its environmentally friendly and sustainable properties further contribute to its appeal as a modern and reliable material for infrastructure projects.
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
