Abstract: The principle of water|coupling ultrasonic inspection of seamless steel pipes was introduced. The high speed scan mode with rotary inspection probes was adopted. And the mechanical rotary organ was designed for probe installation. A synchronal inspection mode with multi|probe was presented to detect the flaws of the inside and surface of the steel pipes rapidly and efficiently. Capacitance|coupling mode was adopted to transfer the inspection signals reliably. According to the experiment, the inspection speed of the system can reach 60m/min, and the performance index of the system can also reach the standard of YB/T 4082-2000.
Key words: ultrasonic inspection; probe|revolving inspection mode; capacitance|coupling
