Duplex Stainless Erw Steel Tube the Metal

Duplex Stainless Erw Steel Tube offers excellent resistance to corrosion along with very high mechanical strength, which allows for lighter fabrication and greater design flexibility. With this high corrosion resistance, Duplex Stainless Steel provides more uptime than Carbon Steel or conventional Stainless Steel.

Duplex Stainless Erw Steel Tube's beneficial performance is attributable to a combination of austenitic and ferrite alloys in its microstructure, achieving both strength and high corrosion resistance.

With its myriad applications, the process industries are always in pursuit of highly reliable materials.  Duplex Stainless Erw Steel Tube is widely endorsed by plant operations management and maintenance specialists who appreciate their toughness and ability to withstand the very aggressive fluids inherent in the process.

Compared with some other materials – graphite, ceramic, PTFE or glass, nickel alloys – Duplex Stainless Steel is a reliable and in the long term, a less costly material of construction offering high strength even in highly demanding applications. These qualities have led to acceptance and growth of the use of Duplex Stainless in Pipe, Piping Systems, Reactors, Columns, Towers and Storage Tanks as well as Shell and Tube Heat Exchangers in sulfuric acid processingas well as the production of urea and other fertilizers.

It is important to note that due the proportions of austenitic and ferrite alloys, both Duplex Stainless Steels and Super Duplex Stainless Steels require considerably more care in welding preparation and fabrication procedures.  Inexperience or less than vigilant attention to these preferred practices can contaminate the resulting welding, rendering the fabrication compromised in strength and corrosion-resistance.
