Ultrasonic Thickness Measurement (UTM) is a non-destructive method that measures the thickness of materials using high-frequency sound waves. A probe is placed on the surface of the material and the transmitted ultrasonic waves travel through the material and reflect back from the opposite surface. By measuring the round-trip travel time of the waves, the thickness of the material is calculated with high accuracy.
UTM is widely used for thickness, wear and corrosion checks on ship hulls, tanks, pipelines and other metal structures.
Typical Applications
- Ship hull and structural thickness gauging
- Storage tank shell and floor surveys
- Pipeline and process piping wall thickness
- Pressure vessel and boiler thickness checks
- Corrosion and erosion monitoring
- Remaining-life and fitness-for-service data
Why UTM (Ultrasonic Thickness Measurement)?
- Fast, quantitative readings from a single side
- No need to take equipment out of service
- Ideal for corrosion and erosion trending
- Class-accepted data for marine thickness surveys
