Ultrasonic Inspection

Ultrasonic inspection uses sound waves of short wavelength and high frequency to detect flaws or measure material thickness.

Usually pulsed beams of high frequency ultrasound are used via a hand-held transducer which is placed on the specimen. Any sound from that pulse that returns to the transducer like an echo is shown on a screen which gives the amplitude of the pulse and the time taken to return to the transducer. Defects anywhere through the specimen thickness reflect the sound, back to the transducer. Flaw size, distance and reflectivity can be interpreted.

CORROCONT performs ultrasonic testing of storage tanks, pipelines and other metal structures by its engineers holding at least UT level II certificate.
