ASME B31.1 Paragraph B.4.1.1
(OP)
ASME B31.1 Paragraph B.4.1.1 indicates that for socket weld connections the branch size must be the smaller of NPS 2 or 1/4 the nominal size of the run.
Would this prohibit, for example, installing a 1/2" sockolet on a NPS 1.5 pipe? Is there a difference if the branch terminates in a drain valve or instrument ?

I do not see a prohibition against 1/2" SOLs on 1.5" pipe. I think it is explicitly permitted by 104.3.1(B.2).
