Common questions
What is the inside diameter of NPS 36 schedule 10 pipe?
35.376 in (898.6 mm). The outside diameter is fixed at 36.000 in (914.4 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 36 schedule 10 pipe weigh?
118.92 lb/ft (176.97 kg/m) empty, as plain-end carbon steel. Full of water it comes to 545.03 lb/ft (811.10 kg/m), because the bore holds 51.060 US gallons per foot. One short ton of this pipe is about 17 ft.
Does NPS 36 schedule 10 pipe use special flanges or fittings?
No. Flanges and buttweld fittings are dimensioned from NPS, so NPS 36 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 35.376 in (898.6 mm) to match.
