Advantages of Ductile Iron Pipe
Greater ductility than cast iron
Greater impact resistance than cast iron
Greater strength than cast iron
Lighter and easier to lay than cast iron
Simplicity of joints
Joints can accommodate some angular deflection
Low pumping costs due to large nominal inside diameter
