Measuring pitting
Measuring pitting
(OP)
I have erossion pitting in an inch and a half diameter tube. I need an easy method for measuring extend of pitting, to put a measurement value on failure/nonfailure of the part. What kinds of easy, cheap measurement methods are available?

More sophisticated techniques range from the semi-automated UT thickness testing from inside the tube already suggested, to IR inspection, to discrete manual thickness testing with UT instrumentation, to laser internal inspection (similar in concept to IRIS, but using a laser to measure the ID) and radiography.
