Eddy Current Testing (ECT)

Uses electromagnetic induction to identify changes associated with discontinuities and material condition.

Eddy-current tube inspection instrument and data acquisition computer.

Eddy-current tube inspection instrument and data acquisition computer.

Understanding the technique

Uses electromagnetic induction to identify changes associated with discontinuities and material condition. Tube inspection signals are interpreted against suitable reference standards.

Where it adds value

Compatible heat-exchanger and cooler tubing, particularly non-ferromagnetic materials.

The purpose is to provide evidence that supports a defined asset decision: prioritizing maintenance, investigating degradation, assessing serviceability or documenting equipment condition. The examination is planned around the asset's operating context and the information needed by the owner.

Inspection outputs

Tube-by-tube findings, recorded signals and recommended follow-up for relevant indications.

Planning considerations

Material, wall thickness, tube geometry and deposits influence response and technique selection.

From scope to decision

Review the asset

Provide equipment identification, drawings, material details, operating conditions and previous inspection records where available.

Agree the examination plan

Confirm the inspection objective, accessible locations, coverage, acceptance basis, site arrangements and reporting requirements.

Document and evaluate

Review recorded findings against the agreed scope, identify any coverage limitations and define the need for further inspection or engineering assessment.

Project questions

What information helps define a quotation?

Share the asset type, location, quantity, inspection objective and desired schedule. Drawings, previous reports and access information help the team prepare a realistic scope.

Can this technique be combined with other services?

Yes. Complementary examination or engineering assessment may be needed to characterize relevant findings. The combination depends on damage mechanisms, material, geometry and the decision required.
