Dimensional tolerances for asme vessels

[Ahmed Habashy]

Hi
We are constructing new vessels according to ASME VIII
My question is
Is there limitations of spacing between nozzles openings and weld toes of shell as api650 para 5.7
And if there is dimensional tolerances for radius,verticality,nozzles ...etc

ASME VIII Division 1 has very few tolerances. Most can be found by searching for "tolerance" in the Code, but I think this misses UG-80.

However "good engineering practice" will still require you to determine appropriate weld spacing rules, etc.

Customers often have nozzle location, verticality, etc. tolerances to match their piping.
