EN545 DI Pipe

EN545 DI Pipe, also known as EN545 Ductile Iron Pipe, is a versatile and durable pipe commonly used in water supply and sewage systems. These pipes are made of ductile cast iron, a material known for its high strength and impact resistance. EN545 DI Pipes are designed and manufactured according to the EN545 standard, which specifies the requirements for pipes, fittings, and accessories for water pipelines.

One of the key benefits of EN545 DI Pipes is their high mechanical strength, which allows them to withstand high pressure and external loads without deformation or rupture. This makes EN545 DI Pipes particularly suitable for underground and above-ground water supply networks, where the pipes are exposed to various environmental conditions and stresses. EN545 DI Pipes are also resistant to abrasion, making them ideal for conveying abrasive fluids and slurries without deteriorating over time.

In addition to their strength and durability, EN545 DI Pipes are known for their smooth internal surface, which minimizes friction and reduces the risk of clogs and blockages in the pipeline. This helps maintain a consistent flow of water and prevents potential disruptions in the water supply system. The cement mortar lining inside EN545 DI Pipes also acts as a barrier against contaminants and pathogens, ensuring the quality and safety of the water being transported.

EN545 DI Pipes are widely used in municipal water supply systems, wastewater treatment plants, industrial applications, and irrigation networks. They are preferred for their superior performance, ease of installation, and low maintenance requirements. EN545 DI Pipes have a long service life, typically exceeding 50 years, which makes them a sustainable choice for water infrastructure projects.

Overall, EN545 DI Pipes offer a reliable and efficient solution for water supply and sewage systems, with their high mechanical strength, corrosion resistance, and smooth internal surface. These pipes are designed to meet the demands of modern water infrastructure projects, providing a durable and cost-effective solution for transporting water and wastewater. Whether used in urban or rural areas, EN545 DI Pipes are a trusted choice for ensuring a safe and reliable water supply for communities around the world.

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
