ASME B36.19M Stainless Steel Pipe
ASME B36.19M-2004 covers dimensions of welded and seamless austenitic stainless steel pipe (NPS 1/8–NPS 30, DN 6–750), with dedicated Schedule 5S/10S/40S/80S wall designations (the ‘S’ suffix distinguishes stainless schedules from carbon-steel schedules in B36.10M)..
Scope
ASME B36.19M-2004 covers dimensions of welded and seamless austenitic stainless steel pipe (NPS 1/8–NPS 30, DN 6–750), with dedicated Schedule 5S/10S/40S/80S wall designations (the ‘S’ suffix distinguishes stainless schedules from carbon-steel schedules in B36.10M).
Mechanical & Performance Requirements
Dimensional standard for stainless pipe; mechanical properties derive from the material spec (e.g. ASTM A312). Schedule S walls are selected to match common stainless grades’ corrosion and pressure service.
Dimensional Tolerances
OD tolerances mirror B36.10M practice: NPS 1/8–1½ tighter band, NPS 2+ ±1% OD; wall tolerance typically −10% of nominal for S-schedules; length tolerances per agreement.
NDE & Hydrostatic Testing
Inspection follows the material specification (A312: hydro test or NDE of each length; weld seam ultrasonic/eddy-current for welded pipe).
