Tunnel-magnetoresistive-based pulsed Eddy current probe for inspection of corrosion under insulation
The problem of corrosion in the industrial oil and gas pipes has been one of the major contributors in catastrophic structural failures. Among the various types of corrosion, corrosion under insulation (CUI) has been known to cause serious problems. Pulsed eddy current (PEC) non-destructive testi...

description |
The problem of corrosion in the industrial oil and gas pipes has been one of the major
contributors in catastrophic structural failures. Among the various types of corrosion, corrosion
under insulation (CUI) has been known to cause serious problems. Pulsed eddy current (PEC)
non-destructive testing has shown its effectiveness in detecting hidden CUI. Most PEC systems
have been developed by using an inductive coil as their sensing device, while some use a
magnetic sensor which potentially offers better resolution. A new probe design based on a solidstate Tunnel magnetoresistance (TMR) is presented. TMR sensors offer higher sensitivities
compared to other commercially available sensors. The performance of the probe is evaluated
by using ferromagnetic mild steel plates that have thicknesses in the range of 8mm to 12mm at
different stand-offs with a thin aluminium sheet under the probe. The different thicknesses
represent different corrosion levels, while the stand-offs and thin aluminium sheet are to mimic
the insulation of different thicknesses and the cladding in the real pipeline structure. The results
show an overall mean absolute error (MAE) of 0.19 mm, which is better than our existing Halldevice-based PEC probe |
