ECT on Phenolic Impregnated Graphite tubes in Heat Exchager

Dear Members,
We want to carry out Eddy Current Testing on Heat exchangers tubes having material of Phenolic Impregnated Graphite. Size: 2" OD X 1 1/2" ID and about 6 meter long.
So the Thickness of the tube is 6.35 mm.
I want to know that Which method shall be used for Eddy current testing.
What will be the effect of Impregnated Phenolic on Conductivity of Graphite?
what will be the frequency to be used and type of probe?

The inspection of Graphite tubes can be done with the use of special designed eddy current probes. We have done sucessful a few inspections in the past. As always with eddy current techniques, you need a calibration tube with natural or machined calibration defects to find a proper setting and to evaluate the eddy current signals you receive during the inspection.

You are welcome to contact us directly for further support.
