        Ductile iron pipe is a pipe made of ductile cast iron commonly used for potable water transmission and distribution. 

        This type of pipe is a direct development of earlier cast iron pipe, which it has superseded. 

        The ductile iron used to manufacture the pipe is characterized by the spheroidal or nodular nature of the graphite within the iron. 

        Typically, the pipe is manufactured using centrifugal casting in metal or resin lined moulds. 

        Protective internal linings and external coatings are often applied to ductile iron pipes to inhibit corrosion: 

        the standard internal lining is cement mortar and standard external coatings include bonded zinc, asphalt or water-based paint.

        In highly corrosive environments loose polyethylene sleeving (LPS) to encase the pipe may also be used. 

        Life expectancy of unprotected ductile iron pipes depends on the corrosiveness of soil present and tends to be shorter where soil is highly corrosive. 

        However, a lifespan in excess of 100 years has been estimated for ductile iron pipelines installed using "evolved laying practices", 

        including use of properly installed LPS (polyethylene encasement). 

        Studies of ductile iron pipe's environmental impact have differing findings regarding emissions and energy consumed. 

        Packaging of Ductile Iron Pipe:

        Shangahi Metal Corporation provides standard seaworthy packaging to worldwide customers, usually the tubes are packed in bundles, wrapped by plastic bag, fixed by steel strip, and then placed in the container with steel wire fixing.
