Infrared Thermography (IR)
Method Overview
Non-contact temperature distribution analysis to detect thermal anomalies, insulation voids, and structural delaminations.
Core Method Specifications
Target Applications & Governing Standards
1 Scopes ConfiguredMethod Limitations & Operational Boundary Conditions
Critical physics limits, thermal envelopes, blind spots, and ASME Sec V / API procedural boundaries for IR.
Direct sunlight exposure, solar loading, and wind speeds > 15 mph (24 km/h) wash out thermal gradients on outdoor assets.
Requires active heat flow / thermal gradient (minimum Delta T >= 5°C) between internal process and external surface
None (non-contact optical radiation detection)
Direct optical line of sight: camera angle of incidence should be within 45° of perpendicular to avoid emissivity drop-off
- •Assets with zero heat flux (isothermal conditions where internal fluid temperature matches ambient)
- •Shiny unpainted aluminum or galvanized insulation jacketing reflecting sky radiation and operator body heat
Solar gain reflections on western pipe exposures during late afternoon mistaken for refractory thinning hotspots
Direct high-temperature UT thickness measurement on hot spots detected on fired furnace tubes
Visual internal borescope check of refractory lining tiles and anchor pins
