Table PW-11 as per ASME Sec I: 2017, states that all longitudinal welds are to be volumetrically examined throughout their entire length.
Now. Considering the case of ASME SA 312 welded pipes (welded without addition of filler metal), ASME sec II part A: 2017 does not mandate volumetric examination on its longitudinal welds. There is an option between hydrostatic test and volumetric examination.
The question is, if ASME SA 312 welded pipe is used for a Code stamping job or Boiler Proper Piping Job, is it mandatory that all the longitudinal welds of ASME SA 312 welded pipes to be volumetrically examined?
