Stainless Steel Pipe Schedule Chart — ASME B36.19M
Stainless steel pipe schedule chart to ASME B36.19M: outside diameter, wall thickness and weight for schedules 5S, 10S, 40S and 80S.
The suffix S identifies the stainless steel schedules. 40S and 80S match Schedule 40 and 80 of ASME B36.10M up to NPS 10" and 8" respectively. Teshi Group stocks and supplies stainless pipe to ASTM A312 TP304/304L and TP316/316L.

Notes
- Weights are calculated on a density of 7.85 g/cm³. For austenitic stainless steel multiply by 1.010 (grade 304) or 1.017 (grade 316).
- A dash means the schedule is not listed for that size.
Reference information compiled from the published standard for convenience. It does not replace the current edition of the governing standard, which takes precedence.
