Square flange 304L #1500 with 4 bollt B16-nut gr 4
Square flange 304L #1500 with 4 bollt B16-nut gr 4
(OP)
Does someone know how to calculate a square flange with 04 bolts ?
ASME VIII-I Appendix 2 is intended for circular flanges. I don't find recommandations for using square flange.
Flange is made with forged stainless steel (304L) and assembled with 4 bolts ½" B16 and nuts grade 4. Flanges have #1500 class and worked with steam.
Perhaps, the appropriate design is doing the burst test !
What do you think ?

Moreover their behaviour is completely different with respect to ring flanges and so is the calculation procedure.
Unless of course you can calculate a ring flange that is totally included in your square flange.

RE: Square flange 304L #1500 with 4 bollt B16-nut gr 4
has a way to get an equivalent circular flange based on the Z factors of UG-34. [get an equivalent ID based on Z, then add cross-section dims to get OD/BCD/G, etc...
There's also the SAE Rectangular Hydraulic Flanges for high pressures.
{Code 61 & 62 3000/6000psi}

Non-circular pressure flanges with circular bore
are designed based on an equivalent circular flange.
See Appendix 2 of Sect. V111 Div 1, Section 2-10 for
the procedure of determining the O.D. and B.C.D. of
the equivalent circular flange.
BTW, ASME Section V111, Div. 1 have never prohibited
the use of non-circular flanges in pressure vessels,
unless there's a new addendum to the code.
