Eddy Current | JSc Inspections

Eddy Current Method

This is a method for inspection of non-ferromagnetic tubes in heat exchangers. The test is performed with a bobbin coil that produces an electromagnetic field in the tube. When the probe is pulled across a discontinuity, the electromagnetic field is distorted. This distortion in magnetic field changes the coil impedance that is related tot he discontinuity. For special defects or defects at special locations a rotating probe is used.

Defects that can be detected:

  • wall loss
  • pitting,
  • cracking,
  • erosion/corrosion,
  • baffle hammering

Inspection techniques:
internal coaxial probe, rotating probe
