Common questions

What is the inside diameter of NPS 30 schedule 10 pipe?

29.376 in (746.2 mm). The outside diameter is fixed at 30.000 in (762.0 mm) by ASME B36.10M, and the 0.312 in (7.9 mm) wall takes 0.624 in off it — 0.312 in from each side — leaving that bore.

How much does NPS 30 schedule 10 pipe weigh?

98.93 lb/ft (147.22 kg/m) empty, as plain-end carbon steel. Full of water it comes to 392.75 lb/ft (584.48 kg/m), because the bore holds 35.208 US gallons per foot. One short ton of this pipe is about 20 ft.

Does NPS 30 schedule 10 pipe use special flanges or fittings?

No. Flanges and buttweld fittings are dimensioned from NPS, so NPS 30 hardware fits this pipe in any schedule. The one thing that does follow the schedule is the bore of a weld neck flange or a fitting end prep, which has to be 29.376 in (746.2 mm) to match.
