Ultrasonic thickness measurement (UTM) is a non-destructive testing method used to inspect the thickness of various materials.
Thickness measurement is essential across many industries to monitor corrosion, erosion, and damage. Ultrasonic thickness measurement is commonly used and the method can be applied to a wide range of structures and components.
Detection of metal loss casued by corrosion, erosion, or damage is vital to ensure the continued safety and operation of the inspected item/structure. It can also help determine if repair work or replacement is needed or if the item/structure should be retired. Ultrasonic thickness measurement data gives customers the necessary information required to determine if the tested item has the adequate thickness for which it was designed.
How it Works
An ultrasonic thickness guage works by precisely measuring how long it takes for a sound pulse that has been generated by a small probe called an ultrasonic thickness transducer to travel though a test piece and reflect back from the inside surface or far wall. From this meaurement, the thickness of th test piece is calculated and displayed on a digital screen.
The portability of the testing equipment allows for on site inspection and results are instant.
We work with our clients to devise measurement regimes at suitable time intervals to monitor the condition of the item throughout its lifetime.
