The main components of ductile iron pipe are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Implementation of the standards GB / T13295-2003 ISO2531 / 2003, with excellent corrosion resistance, good ductility, good sealing effect, easy installation. Ductile iron pipes are mainly for municipal, industrial and mining enterprises water, gas, oil and so on.
Ductile iron pipe production process is in the ordinary cast iron pipe raw materials added magnesium, calcium and other alkaline earth metal or rare metal casting. Ductile iron pipe casting process with continuous casting method, thermal casting method and water-cooled centrifugal casting method, in which the water-cooled method for the world's most advanced technology, technology ductile iron technology performance.
Compared with ordinary cast iron pipe, ductile iron pipes not only maintains the corrosion resistance of ordinary cast iron pipe, but also has the advantages of high strength, good toughness, thin wall, light weight, impact resistance, large bending property and convenient installation. Therefore, ductile iron pipe is not only widely used in foreign countries, but also in the country has also been very good use of promotion, in many parts of China, ductile iron pipe in the medium and small-diameter water supply pipe has been widely used.
