Using bar stock to make pressure vessel flanges
Using bar stock to make pressure vessel flanges
(OP)
Can bar stock material (per ASME sec. II - say SS316L per ASME A 479) be used to make flanges in pressure vessels per ASME B&PV std.? I have notes in ANSI B16.5 that only Forgings / Castings & Plate Stock is Permitted.

WOW.. does it mean that we could use barstock per SA 479 when we specify SA 182 on our flanges?

In 4.4 of SA-182, it is clear that flanges of any type are to be made from forgings, in other words they are exempt from using other Specifications. If you go on to read 4.5, it is clear that the finished product specification shall be a forging, as defined in ASTM A-788. SA-479, SA-234 or SA-403 can be used to fabricate small cylindrically shaped parts supplied under SA-182.
