Is it a flange? If so, it can be treated as reinforcement for a thick-walled pipe

Treat the flange as a pipe connection for hole-strengthening calculations; there is no need to remove the screw holes. If a more accurate calculation is desired, simply subtract the area of the two screw holes within the cross-section (in which case manual calculation may be required).

What the poster is referring to is the integral flange on the spherical tank; if that’s the case, considering drilling holes in the forged piece would be necessary

If one really wants to perform the calculation, refer to Article 16 of HG20582-98
