Ductile iron pipe production process is made of the ordinary cast iron pipe raw materials and magnesium, calcium and other alkaline earth metal or rare metal. Ductile iron pipe casting process has continuous casting method, hot casting method and water-cooled centrifugal casting method, which water-cooled method is the world's most advanced technology.
Compared with ordinary cast iron pipe, it 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, bending performance and easy installation.
So ductile iron pipe is not only widely used in foreign countries, but also has also been a very good use in the country, in many areas, ductile iron pipe has been widely used as small or medium diameter of the water pipe.
