Eddy current testing is a method of non-destructive testing (NDT) that is based on the principles of electromagnetism. When an eddy current probe is energized at a given alternating frequency while in close proximity to a conductive test specimen, eddy currents are induced in the test specimen by means of electromagnetic induction.

How Often Should Eddy Current Testing Be Performed?
Consistent performance of eddy current inspections permit accurate forecasting of maintenance and repair or replacement activities. Maintaining high levels of heat exchanger and condenser performance and system reliability requires regularly scheduled maintenance and inspections.
Ideally, an eddy current test will occur approximately every 3 to 5 years, possibly more frequently if there is active damage occurring that should be monitored. The actual amount of time between testing periods will rely on a number of factors, such as the amount of damage that was identified in the heat exchangers or condensers.
Every situation is unique, The Merrick Group uses the latest technology coupled with extensive experience to determine your components’ condition. Our knowledgeable staff will provide guidance for operational and maintenance activities to improve system performance and reliability.

How effective is Eddy Current Testing?
An eddy current test is extremely sensitive to defects in the tube wall and is the most efficient method for detecting and depth sizing tubing flaws.
Accurate depth sizing requires the use of calibration standards that mimic the damage mechanism. Eddy current testing is best used as a method to assess the condition of a component, particularly the tubing in a component, but other information on component condition can be identified. As part of the condition assessment program, degradation detected by current testing can be re-inspected over time to determine if degradation is ongoing and to trend degradation through the life cycle of the component.
Thank you again Team Merrick. The team was fantastic. Ashley, Brant and Russ’s leadership stood out to me as well. We are very pleased with the work that was performed.
