Dutile Iron Pipe：
Ductile iron pipe is pipe made of ductile cast iron commonly used for potable water transmission and distribution. 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.
