AcousticEye: Boiler, Fin Fan Tube Inspection Tool
January 23, 2012
Inspection of tubes up to 4 inches inner diameter in any shape or material can be achieved for boilers, fin fans, and other heat exchangers with the Dolphin G3™. Achieving speed as fast as 10 seconds per tube, the tool features patented acoustic pulse reflectometry (APR) technology, enabling accurate and reliable noninvasive inspection of tube sizes and configurations. This includes customized adaptors to fit tubes of any internal diameter up to 4 inches, a transducer, microphone, controls, and LCD screen. Inspection setup is performed via a connected external computer that also records and analyzes test data using specialized software. The tube inspection tool guides the technician through all the steps necessary to carry out a job — tube sheet mapping, parameter input, measurements, verification, and report generation. An intuitive graphic user interface, including right-click functions, makes scrolling, zooming, and navigation easy. The Dolphin 3G presents an easy-to-read online report (with drill down options) to the technician for verification, as well as a final summary report including tabular reporting and screenshots of the detected flaws in PDF or HTML format.
