We offer our two cents on product selection too, guiding you through the plethora of resources and choosing the best for you. With us, you can be guaranteed for the finest customer experience. We are a manufacturer, supplier and exporter of Duplex Steel Pipes that are compliant to ASTM A789/790, a specification that covers pipes with a nominal wall thickness that are recommended to use in general corrosive services.
our Duplex Steel UNS S31083 Pipes have a high strength and impact toughness, combined with the superior abilities to resist pitting and crevice corrosion. Biofuels plants, pressure vessels and bleaching equipment are connected using these corrosion-countering pipes. Our ASTM A789 Duplex & Super Duplex Steel UNS S32205 Seamless Pipes have a high degree of weldability and are hardened through cold working, however, they are slightly difficult to machine. We supply ASTM 790 Duplex Steel DIN 1.4462 Welded Pipes to the food processing industry.
