Centrifugally Ductile Cast Iron Pipe is a kind of pipe made from spherical graphite cast iron by centrifugal spinning process. The pipes, which can convey many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility.
With its high strength, high elongation, corrosion resistance, resistance to shock, easy construction and many other fine features, ductile iron pipe is the best choice in today's world for conveying water and gas safely. Ductile iron, also called nodular iron or spheroidal graphite iron, is characterized by the presence of spheroidal graphite in the resultant castings.
Ductile iron pipes are available in a range of diameters from 80mm to 1600mm and are suitable for both potable water transmission and distribution (in accordance with BS EN 545) and sewerage (in accordance with BS EN 598).
Ductile iron pipes are simple to joint, can be laid in all weather conditions and often without the need for selected backfill. Its high safety factor and ability to accommodate ground movement make it the ideal pipeline material for a wide range of applications.
