Internal Rotary Inspection System (IRIS)

Uses a rotating ultrasonic beam inside a tube to measure wall condition around its circumference.

Multimode tube inspection platform supporting IRIS alongside electromagnetic tube methods.

Understanding the technique

Uses a rotating ultrasonic beam inside a tube to measure wall condition around its circumference. The technique provides a thickness profile along the inspected length.

Where it adds value

Heat-exchanger, boiler and cooler tubes where bore access and preparation are suitable.

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-wall measurements, localized thinning indications and a tube condition summary.

Planning considerations

Tube cleaning, water coupling and controlled probe movement are important for reliable data acquisition.

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.
