Ductile Cast Iron Pipe
Product Description

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.

Products strictly meet the below standards:
ISO 2531 Ductile iron pipes, fittings and accessories for pressure pipelines.
BS EN545 Ductile iron pipes, fittings and accessories and their joints for water pipelines. Requirements and test methods.
BS EN598 Ductile iron pipes, fittings, accessories and their joints for sewage application-requirements and test methods.
ISO 7186 Ductile iron pipes, fittings, accessories and their joints for the construction of drains and sewers outside buildings.
ISO 4179 Ductile iron pipes for pressure and non pressure pipelines-Centrifugal cement mortar lining-general requirements.
ISO 8179 Ductile iron pipes-External zinc coating.
ISO 4633 Rubber Seals – joint rings for water supply, drainage and sewerage pipelines-specs for materials.
ISO 8180 Ductile iron pipes – Polyethylene Sleeve.
