- What it is about:
- Non-destructive testing technique that uses ultrasonic waves to measure material thickness without the need to access both sides.
- How it is done:
- Ultrasonic waves are emitted into the material, and the time it takes for them to return is measured. The travel time is used to calculate the material thickness.
- Where it applies:
- In the inspection of pipelines, tanks, pressure vessels, and other industrial equipment to detect corrosion and wear.
