If you are referring to ASME B31.3, refer para 328.4.2 and 328.4.3, generally it is permitted as stated in the applicable WPS. However in case of HP piping it is 1.5mm (1/16"), that's why most of the WPS states as 1.5 or 1.6mm as permitted misalignment.

I have a query , when there is welding between two CS pipes of
different schedules ( different thickness) needs to be butt welded for
process piping application.
what is maximum variation in the thickness of two pipes , that will
ensure a safe weld.
Is there any code that provides any limitation or guidance .
Regards,
Vivek
