Ductile iron pipes possessthe nature of iron and character of steel, the positiveproperties of high strength, high elongation and corrosion-resistance. It is thebest and wise choice to convey water and gas safely and reliably with ductileironpipes. Adopting centrifugal casting in metal moulds technology, "Xinxing" manufacturesand offers a full range of ductile iron pipes and fittings from DN80mmto DN2600mm, with standard effective length:6m and 8m.the products are manufacturedaccording to ISO2531/BS4772/BS EN545. external protection metallic zine complyingwith the standard ISO8179,and bitumen paint.Internal protection spun theblast furnace cement mortar lining complying with the standard ISO4179.Xinxingmay offer such such special protective linings or coatings as ceramic epoxy, coaltar epoxy or other kinds of materials according to customer,s requirements.
