(OP)
Greetings, I have a doubt about the governing codes or standards in fabrication of tanks accessories as manholes, flush type nozzles and fittings, internal piping (draining and instrumentation), since API 650 doesn't mention any fabrication code requirements for the weld of a flush-type nozzle, or an internal instrumentation pipe, like level meter. Please let me know if I have a misinterpretation in this matter.

The Engineering is responsible for the piping work, either internal or external, which is to be designed using B31.3 code, and the instrumentation per ISA standards, etc.

Note also that piping such as a sump drain operates at very low differential pressure, so it is a very UNcritical application. You could specify other codes or increased weld examination for it, but wouldn't really be gaining anything for the trouble.
