Ductile iron is produced by adding a closely controlled amount of magnesium alloy to a molten iron of low phosphorous and low sulfur content. The magnesium alloy addition produces a remarkable change in the microstructure by causing the carbon in the iron to assume a spheroidal or nodular shape, (as contrasted to the flake form of graphite in gray cast iron), and at the same time producing a finer grained iron matrix in the surrounding ferrite structure. As a result of this remarkable change, a far stronger, tougher, and ductile material is obtained.

In addition to the benefits of long life, corrosion resistance, high structural strength, and tight joints, ductile iron is also readily machinable, an important requirement in any pipe that must be drilled, tapped or cut.

Yongtong ductile cast iron pipe has excellent quality and I am sure you will be satisfied. Angang Group Yongtong Ductile Cast Iron Pipe Co., Ltd. is a subsidiary of the large scale state-owned enterprise. Anyang Iron and Steel Group Co. Ltd., aged of 54 years. As a modern factory of high start, high standard, high quality, it processes the first level production lines with capacity of 250000 tons annual production for ductile cast iron pipes with T type joint. This production line adopts advanced process, especially using 60m regenerative annealing furnace for assuring the pipe’s mechanical property, antisepsis treatment adopting zinc spraying and innoxiously paintings outside and cement lining inside, which are widely used to supply and drain water systems. The raw material (pig iron) for the ductile pipes is provided by itself. This kind of pig iron has been widely used by lots of domestic and foreign users for its excellent properties, including low S, low Ti, and low P contents. So far, the whole company has been certified by SGS ISO9001:2000 and BS EN545 and the production process strictly conforms to the international standards ISO2531 and BS EN545 to ensure the quality and lifetime of every pipe.
