Understanding the technique
Records the prepared surface microstructure on a replica for metallurgical examination. The method supports assessment of changes associated with service exposure without removing a large material sample.
Where it adds value
Furnace and heater tubes and other selected components exposed to elevated-temperature service.
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
Replica records, metallurgical observations and recommendations for further condition assessment.
Planning considerations
Surface preparation and selection of representative locations are essential. Interpretation is combined with service history and other inspection evidence.
From scope to decision
Provide equipment identification, drawings, material details, operating conditions and previous inspection records where available.
Confirm the inspection objective, accessible locations, coverage, acceptance basis, site arrangements and reporting requirements.
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.
