Phased array ultrasonic detection of thin-walled small-diameter tubes in thermal power plants

The effectiveness of the phased array ultrasonic testing process was verified by prefabricated and simulated defects on thin-walled small diameter tubes and by the comparison of results of phased array ultrasonic detection with DR ray detection. The results show that the phased array ultrasonic testing is easy to operate and has a high detection rate. It can also provide a reference for the qualitative analysis of defects by accumulating graphs.
