Dear Amedeo Marino,
Have you considered using “LASER” to inspect your tubes? QUEST designed a “laser” based tube inspection system for the US Navy in 1985 which has many advantages over other conventional NDT inspection methods. Of course there are also limitations such as any method. What type of defects or damage you are attempting to detect and quantify should be the deciding factor when selecting a testing method.
The advantages that the “LASER” method has are:
a) Very High accuracy: +/-0.025mm (0.001”)
b) Inspection Speed: 77mm (3”) per second
c) Does NOT require water or any other type of couplant
d) Set-up and calibration time takes less than 15 minutes
e) Different material types have NO EFFECT on the data quality or accuracy
f) Can inspect “vertical” or “horizontal” tubes with no problem
You may even want to consider this technology as a compliment to the Eddy Current (ET) or Magnetic Flux Leakage (MFL) technique. The very high resolution capabilities can generate high resolution pictures of any flaw located on the ID surface.
If you would like additional information please contact me at:
