UT Wall Thickness testing is widely used to check the thickness of metallic materials used for pipelines, tubes, vessels, tanks and other industrial equipment. It is an important tool in establishing the original dimensions of equipment at the time equipment enters service and in measuring the loss of any wall thickness during service. An ultrasonic sound beam is transmitted by a transducer from the contact surface and reflected from the opposite surface of the material under test, allowing a calculation of the material. This method provides the ability to gauge thickness of material without requiring access to both sides of the object. This information is used to measure rates of loss of material and establish the integrity and remaining life of equipment. UT I WT is a limited qualification because only compression probe applications are considered during the course.
