Dear All,
I have a full gasket face(extending from flange od to flange id) pad type flange.
the flange will be welded to top torispherical dish with a groove and a fillet weld.(same as nozzle fig: UW-16.1 (c))
the flange is having holes for bolts which are tapped holes.
how much thickness should i left after tapping for bolt holes in the flange?
I am considering design of flange as per Appendix y of ASME section VIII Div:01 or should i prefer taylor forge bulletin 502? (It is not a u stamp job nor strictly ASME sec VIII Div:01)
Please help.
Regards
