Slip on Flanges on Boiler External Piping
Slip on Flanges on Boiler External Piping
(OP)
According to B31.1 para 122.1.1(F), you can't use ANSI slip on flanges greater than 4" NPS on BEP? I'm confused by the reference to ANSI. Does this also apply to ASME flanges? The forward to B16.5 says that up until the 1996 edition it was called ANSI/ASME B16.5 so my feeling is they are one in the same.
