Centrifugally cast ductile iron pipe is a kind of pipes of spheroidal graphite cast iron manufactured by centrifugal, spinning process. The pipes, which can convey many fluid media such as water and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public facilities. Being iron in nature while having properties of high strength, good toughness, corrosion resistance etc as steel, they are the substitutes for traditional cast iron pipes and common steel pipes. The pipes are produced with high straightness, high surface finish and high size accuracy, even wall thickness, fine mechanical properties and hard external coating. Flexible pushon joint and rubber gasket are used resulting in a convenient installation of pipes.
