Abstract
A real-time ultrasonic pipe inspection system is provided which utilizes computer processing methods in real-time to create a user-friendly interactive environment achieving ease of operation as well as a combination of consistency, thoroughness and speed in flaw and thickness detection. Two computers are utilized in a distributed processor configuration wherein one of the computers is dedicated to user input/output, while the second controls real-time processing of ultrasonic data with the two computers being connected via a communications highway. Simultaneous dual level sensitivity inspection of a plurality of separate probed areas is possible. Data input is provided via a touch sensitive CRT, while pipe status can be indicated with automatic color-coding, graphic presentation on a system CRT or hard copy. The system is provided with ultrasonic wheel probes comprising rotably mounted transducer block and yoke assemblies for rapid adjustment of helical scan angle for different sized pipe.
