Re: IRIS
It really depends on which kind of defects you want to detect. For internal defects it has no influence. External defects are uncommon in finned tubes

Re: IRIS
Though external defects are uncommon in finned tubes, it should be noted that externals are easily visually inspected.
IRIS application are more generally used to determine remaining thickness of a tube.

Re: IRIS
2 different tubes like A and B
"A" tube is in "B" tube.
In between A and B there is thin metal film all around of tube.

Can you measure this film thickness uniformly with Ultrasonic?

Can the film be measured? Not likely using IRIS. The interface betwen the outside
wall of the inner tube and the film represents a significant density change. It is the
change in densities that trigger the return pulse that ends a measurement. No matter how
tightly the bond, even the most minor changes trigger a return pulse. It is this reason that even bonded bi-metallic tubes cannot be fully inspected using the IRIS unit.
