ASTM A790 S31803 Duplex Steel Pipe

ASTM A790 is the standard specification for seamless and welded ferritic/austenitic stainless steel tubing.

ASTM A789 and ASTM A790 Duplex stainless steel tubing is typically manufactured using either the seamless or welded process. For seamless tube, a solid billet of the material is heated and then passed through a piercing bar to create a hollow tube. The tube is then rolled to the required thickness and cut to length. For welded tubes, the material is first formed into a flat sheet. The sheet is then rolled into a tube shape and welded along the longitudinal seam. The welded tube is then heat treated to remove any residual stresses and improve its mechanical properties.

Our A790 UNS S31803 welded pipe is also hydrostatic tested after production, which is an essential step to ensure its safety and compliance with regulatory requirements.
