Description features:Specifications:Ductile Cast Iron is a new material developed in the fifties of the 20th century.It's an Iron/carbon/silicon alloy, in which the carbon exist in the formof free spheroidal graphite. This kind of spheroidal graphite eliminate the effectof cutting the iron matrix that make it become brittle and crack as well as theappearance of stress concentration brought about from flake graphite, thus theDuctile Cast Iron is tough and tensile. People often say that Ductile Cast Iron possess the nature of Iron and charactersof steel.Centrifugal Ductile Cast Iron Pipe is made of spheroidized molten iron using centrifugalcasting technique. Compared with pipes of other material, it has many excellentproperties such as higher strength, higher elongation, better corrosion-resistanceand anti-knocking, Therefore, it is increasingly widely used in transportationfor watergas worldwide.
