Development of a Probe for Ultrasonic Testing of Tubes
Rubem M. Braga, UFRGS, Porto Alegre, RS, Brasi
ABSTRACT The integrity of tubes used in heat exchangers is inherently difficult to evaluate by non destructive tests. In order to develop a quick and reliable way for measuring the wall thickness of these tubes, a special ultrasonic probe was constructed. Tests performed in laboratory and in the industry were carried out using tubes 36 mm in diameter with a nominal thickness of 4.2 mm. The results indicate that measurements with an accuracy around 0.1 mm can be achieved in the determination of tube walls thicker than 2 mm.
