Ultrasonic Thickness Gauging
Repeatable wall-thickness measurement at defined locations.
Safety boundary: this page is conceptual. It does not provide ionizing-radiation source handling, pressure-test procedures, hazardous chemical recipes, energized test instructions, machine settings or robot operation.
What this topic covers
Repeatable wall-thickness measurement at defined locations.
Core testing ideas
Thickness gauging can support corrosion or erosion trending.
Localized damage can make a small set of readings unrepresentative.
Safe remaining life and retirement thickness require applicable engineering criteria.
Measurement and method limits
Method capability depends on material, geometry, access, surface condition, calibration and operator competence.
Evidence and traceability
Indications require interpretation and comparison with approved acceptance requirements.
Using the result
Hazardous radiation, pressure, chemicals and machine-operation details are intentionally excluded.
