Ductile Iron Pipes 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.
