Looking for a reliable ductile iron pipe that meets international standards? Our ISO 2531 / EN 598 K9 ductile iron pipes (DN80–DN2600) are the ideal choice for water supply, wastewater, and infrastructure projects. Manufactured by Jingang LuoKaiWei, one of the leading and most experienced ductile iron pipe manufacturers in the industry, our pipes are known for their durability, corrosion resistance, and long service life.
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.
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. Jingang LuoKaiWei (ShanXi) Company Limited provides ductile iron pipes and fittings ranging fromDN80mm-DN2600mmin accordance with ISO2531/EN545/598 or GB13295.
