Centrifugal ductile cast iron pipes are ideal pipes for municipal administration, industrial and mining enterprises, urban water supply and gas pipe networks. Centrifugal ductile cast iron pipes feature high intensity, good elasticity, corrosion resistance and simple installation, have the intrinsic quality of iron and the performance of steel, and are updated products of the traditional cast iron pipes and common steel pipes; the company can annually produce more than 200,000 tons of various ductile cast iron pipes with the specifications of DN100-1,600mm and various interface types such as T type, K type, N1 type and S type.
