Ultrasonic Wall thickness, Visual Testing, PT if indicated at specific spots, Spot metallography if indicated... one can do many things but generally such vessels are built to specific codes and so you have enough guidance to follow.

Best regards.

Can you provide more detail? is this really a pressure vessel or a tank? If its cryogenic service why do you want to inspect? Defining the true reason for inspection will then potentially determine what if anything you need to do.

Internally there may be no degradation mechanism - so you may not need to inspect. Externally is it aboveground or buried? These questions all dictate what you may nee dto do.

in general testing is helium testing to testing leakage or not.
