Surface Probe Eddy Current Inspection of Tubing

Has anyone here ever used a surface eddy current probe to examine stainless steel tubing? Specifically small diamter tubing (<= 1/8"). If anyone has any insight or links to information related to this they could offer I would appreciate it. Please send an email to: ddlucero@lanl.gov.

Hi,
i did testing of stainless steel in german nuclear power plants. We were searching (successfully) for inside defects with eddy-current probes from the boundary of the tube.
More relevant than the diameter is the wall-thickness.
I hope, I can help you

Hi,

SS tubes (austenitic) are normally tested during manufacture using an encircling coil from OD and during in-service inspection using an ID Bobbin coil. I would like to know the type of defects that you are trying to detect with the surface probe.
