Eddy Current Array



The conventional ECT faces major limitations with respect to detection & sizing of circumferential cracking and extent of volumetric flaws in tubular. Rotating probes is a solution but it reduces the inspection speed. Therefore Eddy Current Array along with bobbin probe technology is the solution to perform high speed inspection in a single pass.




Advantages of ECA:

  • One-pass inspection providing bobbin and array probe signal High definition which provide reliable and repeatable detection of small defects whatever the position around the circumference
  • High sensitivity to pitting and circumferential cracking (ID and OD circ. crack detected down to 20% depth and 25° extension)
  • More reliable characterization of flaws with C-scan imaging improved detection of circumferential cracking under tube sheets
