Specify the complete pipe route
ASTM A790 covers duplex pipe, but the order must still state seamless or welded construction, NPS and schedule, length, end preparation, testing, marking and certificate requirements. Dimensions commonly reference ASME B36.19M.
Duplex-specific controls
Chemistry, heat treatment and cooling create the intended austenite-ferrite structure. Projects may add ferrite or phase checks, impact tests, ASTM G48 corrosion tests, PMI and stricter repair-weld controls.
System compatibility
Pipe, fittings, flanges, bolting and welding consumables should be reviewed as one piping class. Mixing components by nominal grade alone can create documentation or corrosion gaps.
