ASTM A790 UNS S31803 Duplex Stainless Pipe

The SA 790 UNS S31803 Tubing is also highly corrosion resistant in sea water and other chloride ion rich environments. This chloride ion corrosion stress cracking resistance makes it one of the best cost effective solutions in the long run. The Duplex 31803 Seamless Pipes are used in high sensitive applications where the measurements need to be accurate. But the seamless nature reduces strength compared to the Duplex UNS S31803 Welded Pipes. 

The applications of A790 gr S31803 DSS ERW Pipes could be seen in sea water and marine environments, chemical industries, food processing plants, heat generators, automobile components, parts of boilers and other high temperature applications. The electric fusion welded Duplex S31803 UNS EFW Pipes can also be used interchangeably with less specific application requirements.
