Hello Lalit,

The best method is to opt for 3 D laser Scanner which gives you the exact result , rathen than to opt for pit depth gauge which is time consuming. I have seen this instrument and it is really awesome. Please find the attached document. I believe that this follows the ASME B31, but not sure.

You can ask for a demo to the following contact person

Pulsed thermography method is one of known IRT method, it is good and precise for this kind of job.
With this method, you can also see the impact of damage of the corrosion under the surface.
