ultrasonic testing, the most powerful and easiest inspection method in oil and gas industry

Ultrasonic testing One of the most common and easiest inspection methods in the oil and gas industry is Ultrasonic testing or commonly known as UT. UT is a non-destructive testing technique based on the propagation of ultrasonic waves in the material tested. Usually, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, is transmitted into materials like carbon steel to detect material thickness or to find internal defect inside the material. UT equipment consists of several parts that have different functions such as Pulser / receiver, transducer, and monitor screen. Pulser / receiver is an electronic equipment that can produce high-voltage electrical pulses. the transducer produces high-frequency ultrasonic energy. The ultrasonic energy is discharged and dispersed through or entered into the test material in a waveform. If there is a defect or discontinuity (such as crack) on the wave path, then some energy will be reflected back from[…]
