Ultrasonic testing is a technique designed for non-destructive testing of pipelines. UT is used to determine the pipe wall thickness providing information on the integrity and pipe wall variation by spot measurements.
Testing using ultrasonics is based on the propagation of ultrasonic waves in a pipe wall, or other material being tested. Very short ultrasonic pulse waves are transmitted into the material and by calculating the reflection time of the sound waves off the wall boundaries, the wall thickness of the material can be determined.
Ultrasonic testing is often performed on steel and other metals or alloys, however it can also be used on concrete, wood and composites, with less resolution. UT can be used to detect flaws or characterise material.
The use of ultrasonic technology spans across many industries including construction, metallurgy, aerospace, automotive and other industries, with the most common use being to measure wall thickness for assessing pipeline integrity.
Ultrasonic testing is a very accurate and cost effective product that can be used for general monitoring operations.
