Do you know the performance comparison between Ductile iron pipe and general cast iron pipe?
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 has continuous casting method, hot-mold casting method and water-cooled centrifugal casting method, in which the water-cooling method for the more advanced technology in the world, different technology nodular cast iron technical performance.
Compared with ordinary cast iron pipe, not only to keep the ordinary cast iron Pipe corrosion resistance, but also has the advantages of high strength, good toughness, thin wall, light weight, impact resistance, bending performance, easy 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 medium and small diameter pipes have been widely used.
