Infrared thermography maps surface radiation to identify abnormal temperature patterns associated with electrical resistance, insulation loss, friction, blockage or process imbalance.
Technical principle and inspection purpose
Infrared thermography maps surface radiation to identify abnormal temperature patterns associated with electrical resistance, insulation loss, friction, blockage or process imbalance. Data quality depends on controlled calibration, repeatable location referencing, suitable surface or access conditions and preservation of the original inspection evidence.
For industrial thermal inspection, the technical principle and inspection purpose stage should document the inspection objective, target flaw, material and component geometry. This stage must remain linked to the asset and original data so later reviewers can distinguish verified condition, interpreted indications, assumptions and areas where further evidence is required.
Where the technique creates value
It supports surveys of electrical systems, rotating equipment, refractory, buildings, tanks, piping and process equipment while operating. Where confidence is limited, the report should recommend verification, complementary NDT, expanded coverage or engineering assessment rather than presenting an unsupported conclusion.
For industrial thermal inspection, the where the technique creates value stage should document the asset locations, access method, expected coverage and operating constraints. This stage must remain linked to the asset and original data so later reviewers can distinguish verified condition, interpreted indications, assumptions and areas where further evidence is required.
Planning and procedure requirements
Load, emissivity, reflected temperature, distance, weather, viewing angle and baseline comparison affect apparent temperature and must be controlled or recorded. Applicable codes and standards provide a framework, but the governing document and edition must be established for the specific asset and contract.
For industrial thermal inspection, the planning and procedure requirements stage should document the approved procedure, calibration basis, essential variables and personnel responsibilities. This stage must remain linked to the asset and original data so later reviewers can distinguish verified condition, interpreted indications, assumptions and areas where further evidence is required.
Important limitations and complementary methods
Thermography generally identifies surface thermal symptoms, not the underlying defect. Shiny surfaces, wind and changing process conditions can produce misleading contrasts. For industrial facilities in the UAE and GCC, selection must also reflect operating temperature, environmental exposure, access restrictions, shutdown windows and the owner’s technical requirements.
For industrial thermal inspection, the important limitations and complementary methods stage should document the unexamined zones, detection boundaries, uncertainty and required complementary checks. This stage must remain linked to the asset and original data so later reviewers can distinguish verified condition, interpreted indications, assumptions and areas where further evidence is required.
From inspection evidence to an engineering decision
Reports should retain thermal and visible images, measurement settings, operating condition, severity logic and recommended confirmation or corrective action. A competent team should define the intended result before mobilisation so equipment capability, scanning coverage and reporting detail are aligned with the client’s decision.
For industrial thermal inspection, the from inspection evidence to an engineering decision stage should document the evaluation basis, indication disposition, follow-up action and retained evidence. This stage must remain linked to the asset and original data so later reviewers can distinguish verified condition, interpreted indications, assumptions and areas where further evidence is required.
How IAIS UAE can support this requirement
Integrity & Advanced Inspection Solutions UAE can support clients in developing an appropriate scope for industrial thermal inspection. Depending on the approved requirement, support may include technical review, procedure and scan planning, equipment configuration, field examination, encoded-data analysis and traceable reporting. Final methods, acceptance criteria, personnel requirements and deliverables are agreed for the component, expected degradation, governing requirements and client decision.
