ULTRASONIC MATERIAL TESTING ( UTM )
CIVIL - MARINE - OIL/GAS - WATER/SERVICES
Kent Structural & Architectural Ltd
We provide a service for material thickness testing requirements for a variety of applications
whether you require existing structures testing or damaged areas varifying, we can be of service.
All of our equipment is dual probe based testing to enable us to measure thinner materials if required.
Areas of work include
We have a variety of testing equipment at our disposal and will even consider underwater testing applications if required.
Basic principle of UTM
A probe sends a sound wave into a test material. There are two indications, one from the initial pulse of the probe, and the second due to the back wall echo.
Any defect creates a third indication and simultaneously reduces the amplitude of the back wall indication.
The depth of the defect is determined by the ratio D/Ep
About the process
In the field of industrial ultrasonic testing, ultrasonic thickness measurement (UTM) is a method of performing non-destructive measurement (gauging) of the local thickness of a solid element
(typically made of metal, if using ultrasound testing for industrial purposes) basing on the time taken by the ultrasound wave to return to the surface. This type of measurement is typically performed with an ultrasonic thickness gauge.
Ultrasonic waves have been observed to travel through metals at a constant speed characteristic to a given alloy with minor variations due to other factors like temperature. Thus, given this information, called celerity, one can calculate the length of the path traversed by the wave using a given formula
