What is Ductile Iron?


Ductile iron is an iron/carbon/silicon alloy with a nodular graphite structure that produces a strong, ductile

material. With more than double the tensile strength and much higher ductility than that of cast iron, 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.


So Why Choose Ductile Iron Pipes?:

Pipe Manufacture


Ductile iron pipes are manufactured by  centrifugal casting process; this involves pouring iron into a fast revolving mould immersed in a running water bath rotating at a very high speed, creating a cylindrical shape as a result of the centrifugal forces created by the rotation of the mould.

At the same time, the mould is cooled from the outside subsequently lowering the molten metal temperature to allow solidification to take place. Once the cast is extracted from the centrifugal casting machine, it is then subjected to heat treatment to enhance its mechanical properties prior to hydrostatic testing and application of internal linings and external protective coatings
