Ductile Iron pipes normally possess thicker pipe walls and are generally stiffer than steel pipes. As such, it relies less on side fill soils to support external loads so it is necessary to achieve highly-compacted soils for ductile iron pipes for sustaining external loads.

Ductile iron pipe in the medium and small caliber to give the connection between the pipe and the pipe, using socket or flange type interface method; ductile iron, allowable limit of the corner must have superior seismic resistance and sealing. The main components of ductile iron pipe are carbon, silicon, manganese, sulphur, phosphorus and magnesium.
