Phased Array Ultrasonic Testing Technology for Stainless Steel Base Material of Small Diameter Tube in a Nuclear Power Plant

The principle and characteristics of ultrasonic phased array testing technology are introduced. Aiming at the difficulty of conventional ultrasonic testing for stainless steel base material of small diameter tube in a nuclear power plant, a special ultrasonic phased array testing technology is developed. The feasibility of the ultrasonic phased array detection technology is verified by testing and field application.
