Ductile iron pipe in the medium and small caliber to give the connection between the pipe and the pipe, using socket or flange type interface method; ductile iron, allowable limit of the corner must have superior seismic resistance and sealing. The main components of ductile iron pipe are carbon, silicon, manganese, sulphur, phosphorus and magnesium.
