NPS, DN, outside diameter and wall thickness for SCH 5S, 10S, 40S and 80S stainless steel pipes as per ASME B36.19M.
Understanding SS Pipe Sizes & Schedules
Stainless steel pipes are identified by Nominal Pipe Size (NPS) in inches or Diameter Nominal (DN) in mm, plus a schedule that defines the wall thickness. From NPS ⅛" to 12" the outside diameter is larger than the nominal size; from 14" upward, OD equals NPS. The suffix 'S' (5S, 10S, 40S, 80S) denotes stainless steel schedules per ASME B36.19M.

Which Schedule Should I Choose?
- SCH 5S – very thin wall; low-pressure, gravity and large-bore lines
- SCH 10S – most common for water, food and chemical lines
- SCH 40S – standard weight; general pressure piping, threaded lines
- SCH 80S – extra strong; high pressure and threaded small-bore
- SCH 160 / XXS – very high pressure (on order)
