Do you have any experience pulling tubes? There is a significant learning curve to Eddy Current and RFT. As far as I'm concerned, it's voodoo unless I know the technician. There are a handful of people that I've met in my years that I trust. I cannot tell you how many times I've seen bundles sent out for retube and little or nothing found when the tubes were split.
In addition, the probes and standards are unbelievably expensive.
I am not trying to deter or discourage, but ET and RFT require proper training and skill. It's not like IR, buy a camera and figure it out as you go. There is no reference point involved. The screen shows a bunch of squigly lines and swoops. They all mean something, but without proper knowledge, there is no way to tell if its 50% wall loss, a baffle, a crack or something else. |
