How does Division 1 handle external blind holes in flange covers?
How does Division 1 handle external blind holes in flange covers?
(OP)
How does Division 1 handle external holes in flange covers that do not penetrate all the way through? If the hole goes all the way through there are rules for reinforcement. Do they apply to blind holes as well?
Or is there a calculation such as for the minimum thickness over a seal groove?
Thanks.

How it happened?
Why not to replace the cover without external hole?

The approach I am taking is to do FEA to verify that the stress concentrations at the holes do not exceed the criterion for discontinuity stresses (i.e. Sp < 3S).

The problem with sloppy work is that the supply FAR EXCEEDS the demand
