Tapped Hole in B16.5 Blind Flange
Tapped Hole in B16.5 Blind Flange
(OP)
Is there any reference where I can determine what the change (if any) would be to the listed pressure rating of a B16.5 blind flange by tapping a hole in it (of NPS equal to or smaller than the NPS of the flange)? I'd rather not go through the entire calculation per Sec. VIII Div. 1 Appendix 2 if someone else has done the work already.
Thanks.
Thanks.
