Ductile iron pipes refer to pipes that are cast by high-speed centrifugal casting using a centrifugal ductile iron machine after adding nodulizing agent to cast molten iron above No. 18. They are referred to as ductile iron pipes, ductile iron pipes and ductile cast pipes. It is mainly used for the transportation of tap water and is an ideal material for tap water pipelines.

Technical Specification of Ductile lron Pipes and Fittings

The ductile iron materia features similar mechanical properties with carbon steel such as highmechanical strength,good ductility,and the same anti-corrosion performance as cast iron. Thereforeit has gradually become the world’s most safe and reliable pipes and fittings in the field of watersupply and drainage. Jiugang Steel (Qingdao) Company Limited provides ductile iron pipes and fittings ranging fromDN80mm-DN2600mmin accordance with ISO2531/EN545/598 or GB13295.
