¿What do we mean by multifrequency eddy current testing of tubing?
- Multifrequency eddy current testing overcomes most of the limitations associated with single-frequency testing.
- In multifrequency, dual-mode, dual-frequency testing, one pull of the probe provides both an absolute and a differential signal. Each signal has its own frequency and its own phase.
- Dual frequencies penetrate the tube wall differently. Dual phase increases the sensitivity of defect detection.
- Using dual modes in one pull of the probe gives you two tests simultaneously, providing a more accurate tube test.
ADVANTAGES

What determines how often tubes should be eddy current tested?
Centrifugal and absorption units with minor tube corrosion — every three years.
Centrifugal and absorption units with major tube damage found on a previous test — every year.
Centrifugal units with tube support damage — every year.
Retubed units — should have a baseline test.
Any time there is a tube failure in a unit — all tubes should be tested.
Any time a freeze-up condition occurs — all tubes should be tested.
Generators in absorption units with tube support damage — every year.
