PAUT can be used in place of RT and allowed as per ASME SEC VIII DIV 1, check your weld quality before jumping to this mecthod and it is better than RT and with more precision to detect defects. However you need check with your NDT crew or your NDT sub contractors are they having compitent personal to perfrom it is very important that the person who is perfrom this shall be skilled enoughed to operate machines for performing & interpreting results and all the welds in the vessel cannot have sufficient space on either side of the welds for scanning and hence interpretation of results may be difficult in case proper calibration and validation blocks are not place.
please refer ASME Code cases that are allowing PAUT in the lieu of RT
you require to demostrate PAUT mock up prior to NDE test to your client and AI. no of blocks will differ based on your scope take opion of your LEVEL III.
Thanks
