Fin-Fan Air Cooler Tube Inspection
Finned air-cooler tubes often use carbon steel and have geometry that complicates standard eddy current interpretation. Near-field array (NFA), remote field, magnetic flux leakage or IRIS may be considered according to material and target damage. NFA is a related array method, not automatically the same probe or procedure as conventional ECA.

Internal corrosion, pitting and erosion in finned tubing require technique selection against ferromagnetic properties, fin arrangement and access.
Different techniques may be complementary. The inspection procedure must demonstrate response to the target indication under the actual material and geometry conditions.
