Ultrasonic thickness measurements (UTT) classified as non-destructive testing (NDT) methods, they involve the use of longitudinal ultrasonic waves and measuring the wave transit time in the object, which gives the result of its thickness.
This method also allows for determining the wall thickness of pipes, pipelines, tanks, plates and sheets, castings, and other products. It is used during manufacturing and operational processes in cases where one-sided access to the tested object is possible. It is also used to determine the depth of discontinuities in ultrasonic testing and the condition of the entire volume of the tested element. Ultrasonic thickness measurements are performed on objects made of metals, plastics, glass, rubber, glass fibers, composite materials, and other materials.
