35th Annual CNS Conference
2015 May 31 - June 3
Saint John, Canada
Session Title:
1A2 - Refurbishment and Life Extension (I)

RTD-Incotest or insulated component testing, a method of pulsed eddy current, is designed and developed by Applus-RTD for the detection and sizing of corrosion under insulation.

RTD-Incotest measures average wall loss over an area beneath the probe. This is accomplished by measuring the decay curve of the eddy current and then utilizes a software algorithm to determine percent wall loss. If there is a verification point this can also give average remaining wall thickness.

The benefits for the nuclear industry are:
1) No need to remove insulation. Only requires one verification point.
2) Reduces potential exposure/ maintains ALARA
3) Quick and accurate screening method.
For exposed piping there is no need for contact with the piping. So it can be applied for high temperature or for increasing standoff to reduce exposure.
