My question is while scanning UT in inservice line that is 11mm thickness 60″ dia, the thickness is good there is no corrosion noted but one indication is coming at 5mm but that has no length it coming only in one spot if we move the probe it disappears even though it has no length but it is coming everywhere in the pipe at same depth 5 to 6mm,what it would be? Am using 38dlplus & probe is d790? What is the acceptance for this issue? Is that inclusion or nature of the pipe!it is nature of the pipe means it is coming in elbows also! Thanks in advance kindly share your thoughts!
