Overview
- Ductile Iron is an improved variety of Cast Iron invented in 1949.
- It is also known as Spheroidal Graphite Iron or Nodular Cast Iron.
- Centrifugally cast Ductile Iron pipes are one of the most preferred materials for water supply and sewerage applications across the world due to its host of advantages.
- Pipes made from Ductile Cast Iron provide substantial benefits in terms of pressure bearing ability, impact resistance and capacity to sustain external static/ dynamic loading.
