Common questions
What is the inside diameter of NPS 30 schedule 5 pipe?
29.500 in (749.3 mm). The outside diameter is fixed at 30.000 in (762.0 mm) by ASME B36.10M, and the 0.250 in (6.3 mm) wall takes 0.500 in off it — 0.250 in from each side — leaving that bore.
How much does NPS 30 schedule 5 pipe weigh?
79.43 lb/ft (118.21 kg/m) empty, as plain-end carbon steel. Full of water it comes to 375.75 lb/ft (559.17 kg/m), because the bore holds 35.506 US gallons per foot. One short ton of this pipe is about 25 ft.
Does NPS 30 schedule 5 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 29.500 in (749.3 mm) to match.
