Available materials: ASTM A106 Gr B, ASTM A53 Gr B, API 5L Gr B PSL1, ASTM A333 Gr 6, ASTM A335 P11, ASTM A335 P22, ASTM A335 P91, ASTM A312 TP304/304L, ASTM A312 TP316/316L, ASTM A790 S31803, IS 1239 / IS 3589.
Notes
- Weights are calculated for carbon steel at 7.85 g/cm³ from the formula in ASME B36.10M.
- A dash means the schedule is not tabulated here for that size.
- Manufacturing tolerance on wall thickness for seamless pipe to ASTM A106 is −12.5%.

Frequently asked questions
What is the difference between NPS, NB and DN?
NPS (Nominal Pipe Size) is the North American size designation in inches. NB (Nominal Bore) is the same idea used in India and the UK. DN (Diamètre Nominal) is the metric designation in millimetres. They name the same sizes: NPS 4 = 4" NB = DN 100. None of them is the actual outside diameter for sizes up to NPS 12.
What is the outside diameter of a 4 inch pipe?
A 4" (NPS 4, DN 100) pipe to ASME B36.10M has an outside diameter of 114.3 mm (4.500 in) for every schedule. Only the wall thickness and bore change with the schedule.
Why is the OD of a pipe different from its nominal size?
From NPS ⅛ to NPS 12 the nominal size is a historical bore reference, so the OD is larger than the number (a 2" pipe is 60.3 mm OD). From NPS 14 upward, the OD in inches equals the NPS: a 14" pipe is 355.6 mm OD.
What does pipe schedule mean?
A schedule number (Sch 10, 40, 80, 160) sets the wall thickness for a given pipe size. The same schedule gives a different thickness at each size. Sch 40 is 3.91 mm at 2" but 8.18 mm at 8".
