In continuation of my previous comment, use a 5 MHz or 4 MHz dual probe and scan from the the OD surface. For calibration, use the reference as per your specification. Normally it should be a 3 mm flat bottom hole machined in the clad from the ID surface. Any questions, let me know.

Yes, UT is done in the as clad state. Calibration standard is made the same way as the pipe being inspected or as per T 434.4.2 of ASME V.
