Ultrasonic Thickness Testing & corrosion mapp ...

Ultrasonic Thickness Testing (UTT) is a non-destructive testing (NDT) method that uses sound waves to measure the thickness of a material and detect corrosion and other internal discontinuities. UTT is used in a variety of industries, including aerospace, shipping, and fabrication. Here are some details about UTT:How it worksA small probe called an ultrasonic transducer generates sound pulses that travel through the material and reflect back. The gauge measures the time it takes for the sound to travel and reflect, and then calculates the thickness of the material. What it's used forUTT can be used to measure the thickness of a variety of structures and components, including piping, pressure vessels, ship hulls, and structural steel. It can also be used to assess corrosion and erosion in these structures. How it's performedThe transducer is touched to the surface of the material being tested. The material should be clean, flat, and at a moderate temperature. Insulation needs to be removed so the transducer can come into direct contact with the material. FrequencyMost UTT applications use short pulse waves with frequencies ranging from 0.1-15 MHz, but frequencies up to 50 MHz can be used. ...
