Ductile iron pipe has the nature of the iron and steel property. The ductile, refers to the arrangement is spherical graphite in cast iron components, to weaken the body and cause stress concentration effect is very small, so with excellent toughness. Nodular cast iron, also has a high strength, high elongation and corrosion resistance. Easy to install, and other characteristics. Widely used in petroleum, electric power, chemical, and water transportation and gas pipeline engineering.
