Electrosteel Castings Ltd. is an ISO 9001:2000 Company , having a production capacity of 2,50,000 MT of Ductile Iron Pipes and a modern Ductile Iron Fittings Plant. Electrosteel Ductile Iron Pipes are available with ISI certification mark of IS:8329 and BS Kitemark of ISO:2531/EN545/EN598. Electrosteel has the distinction of being the first to set up a Ductile Iron Spun Pipe Plant in India using the latest state of the art technology. It has maintained its technological excellence by continual skill and equipment.
 
In 1949 Ductile Iron was invented and within about 10 years’ time the entire ferrous foundry industry changed their process to produce Ductile Iron. All over the world from intricate castings of automobile engines, shafts, high pressure pipelines, heavy excavators to low technology soil pipes and manhole covers are now being made of Ductile Iron, which is often called Ductile Cast Iron/Spheroidal graphite Iron/Nodular Cast Iron.  This technological evolution happened because Ductile Iron retains all the good qualities of cast iron but has more than double the tensile strength [Cast Iron 180 MPa, (min) Ductile Iron 420 MPa (min)] and has eliminated the brittle nature of cast iron. In India, Electrosteel Castings Limited brought the Ductile Iron Spun Pipe technology only in 1994.
 
Advantages of DI pipes

Reliable and cost effective internal and external corrosion protection
Impermeable to gas and organic contaminant
Easy pipe location when buried
Under pressure connections are not complicated
High tensile strength and High yield strength
High impact resistance and fatigue resistance
High elongation (ductility)
Good Resistance to handling / transportation damage
Simple Push-on type jointing System
Offers Considerable joint deflection
Even unskilled workers can join and lay the pipes
The basic chemical composition of Cast Iron & Ductile Iron being same, the life of Ductile Iron Pipes will be about 100 years due to their excellent Corrosion resistance.
 
Application of Ductile Iron pipes

Ductile Iron Pipeline systems can be used in virtually any location or application encountered 
By the Design Engineer.
Some of the prominent areas of application are:
Conveyance & distribution of raw water & potable water
Sewerage Force main and Gravity collection systems.
Conveyance of gas and other industrial products
Intake water line & Ash slurry disposal systems for Thermal Power Plant
Flanged Pipes within pump house and treatment plants
Penstock for Hydel power plant
Ductile Iron Piling System
