What Are Super Duplex Steel Pipes & Tubes?
Super Duplex Steel Pipes & Tubes are advanced materials renowned for their exceptional properties, combining the desirable characteristics of both austenitic and ferritic stainless steels. With a higher chromium and molybdenum content compared to standard duplex steels, they offer superior corrosion resistance and mechanical strength. These pipes and tubes are highly sought after in industries where harsh environments are common due to their ability to withstand corrosive elements.
Super Duplex Steel Pipes & Tubes display remarkable machinability, making fabrication and shaping during manufacturing easier than ever before. Their flexibility lends them well for applications where precision designs require complex precision. From milling operations to drilling or machining procedures - Super Duplex steel offers efficient production processes at cost-effective production levels.
One of the most notable features of Super Duplex Steel Pipes & Tubes is their exceptional corrosion resistance, surpassing even standard duplex stainless steels. Super Duplex's resistance extends across chlorides environments, acids and alkalis; meaning longevity in industrial settings with reduced maintenance costs and downtime costs.

Melting and Casting
Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.
Rolling and welding
Aluminum Pipes & Tubes may undergo rolling processes to refine their dimensions and improve surface finish. Welding techniques like TIG or MIG welding are utilized for this process
Cleaning and heating phase
These Pipes & Tubes are subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes.
Cold - drawing process
The Pipes & Tubes are coated with oxalic and soap solution. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.
Finishing process
The stainless tubes or pipes thus produced will undergo certain testing and quality checks. This process is followed by proper packing and dispatch.
