Make it easy on yourself; "replace the hole"
Calculate a torus with an area that matches the finished diameter of the nozz hole, and cut a repad with those dimensions from your shell material. Don't forget the 'weep hole' so that the installed repad can be air tested.

Errr haven't you answered your own question? "The pig trap to be designed as per ASME B31.4".....

See section 404.3 or just use "integrally re-inforforced branch connection fittings" AKA weldolets.
