About this episode

The episode discusses eddy current testing of heat exchanger tubes with insights from industry experts.

In this episode, Evan Lowrance, Corporate NDT Engineer at Webco Industries, and Jonathan Konerza, Tubing Division Manager at Sentinel Integrity Solutions, join co-hosts Heather Allain and Marc Cook for an in-depth look at eddy current testing (ECT) of heat exchanger tubes. Together, they break down how ECT works, the differences between internal and external testing, and how factors like magnetism and material conductivity influence test results. The conversation explores how eddy current testing compares to IRIS testing, what types of defects ECT is best suited to detect, and where its limitations exist. Evan and Jonathan also discuss the importance of reference standards, technician qualification, and tailoring inspection programs to expected degradation mechanisms. The episode wraps with practical insight into evaluating NDE providers and recognizing warning signs that testing may not be delivering reliable results. This episode is sponsored by Tricor Metals and Webco Industries. Corrosion Chronicles is produced by Association Briefings.
