Large Diameter 2205 Duplex Stainless Steel Seamless Pipe DN200 ASTM
A790
Duplex stainless was first introduced to the Oil and Gas industry
in the late 1970’s when it was selected for natural gas pipelines.
At the time, this selection choice provided a critical commercial
breakthrough for Duplex 2205 (UNS S32305/S31803).
It helped pave the way for Duplex 2205 acceptance into not only the
Oil and Gas industry, but also into many other industries like food
industry as well.
