Ductile Iron pipes are commonly used for potable water and sewage transportation. Metallic pipes, primarily cast iron had been used over two centuries ago for water and waste water transportation. Ductile iron pipes which belongs to the family of cast Iron have been developed by treating the molten low — sulphur base iron with magnesium under closely controlled conditions. The startling change in the metal is characterized by the free graphite in ductile iron being deposited in the spheroidal or nodular form leading to maximum continuity of metal matrix thereby forming a stronger and tougher ductile material with high ductility and impact strength.
