cracks reveald by IR Termgraphy

Does anybody can advise me if using IR termography I can reveal/ detect a crack/cracks located in a welded seam of a insulated pressure vessel and if is a relaible and usual low cost method to to this. Does anyboby did that.
Regards and thanks in advance,

Hi there

We have used IR on piping with insulation for more than 5 yrs now but so far fail to detect cracks unless those which result in leakage of process medium. The key to IR is temperature difference. Unless you have significant temp diference, you wont be able to detect with IR.

I have experience leakage of steam from steam trap linsulated line. By the time we see it through IR, we can already see condensate seeping out of the cladding. Another disadvantage of IR is heavy reflection on shiny cladding. We prefer to conduct IR at night to avoid reflections from the sun etc.
