NDT - Conventional Ultrasonic Testing
The Objective
The Ultrasonic Inspection process involves transmission of sound waves of short wavelength at high frequencies in order to identify flaws and/or measure the thickness of materials as well as to detect corrosion.
The Solution
Conventional Ultrasonic Testing equipment works with the principle of sending a pulsed beam of high-ultrasound from a handheld transducer, which is placed upon the surface of the object being tested.
This wave will be disturbed and then partially returned from spots with internal imperfection or from the back of the material wall. Capturing and analyzing the return sound collect useful information, which are displayed upon the screen of the ultrasonic equipment, presenting the amplitude of the pulse and the duration taken for return to the transducer.
By measuring this sound a skilled operator can identify location and orientation of imperfection, respectively the wall thickness of the material. Acceptance criteria define whether or not the indication is non-acceptable (a defect) or not.
Application Range
Especially for pipelines the recommended or required way of inspection – a balance between Radiographic Testing and Ultrasonic Testing - has been changing during the last couple of years towards stronger use of Ultrasonic Testing.
