Flange to Flange alignment

[pch1]

I have two skids to be connected together on site.
I am looking for a table or similar that shows the maximum allowable misalignment between two flanges (Face to face misalignment, axial misalignment and rotational misalignment) that would still allow them to bolt together with a pressure tight joint.
The flanges in question are 1.1/2" RF ANSI B16.5 Class 150 Stainless Steel.

Thanks
Paul

1/64 inch across two orthagonal planes. This is roughly the play in stud alignment to the flange holes on diameter.

ASME PCC-1 appendices site the allowable alignment tolerences for flange joining.
