Abstract
A non-destructive testing device for pipes is provided. The device extracts information on defects from signals captured by ultrasound receivers following the selective excitation of ultrasound transmitters according to a selected time rule. The receivers form an arrangement with a selected geometry, coupled in an ultrasound fashion, with relative rotation/translation movement, with the pipe. The device includes a converter that selectively isolates a digital representation of echoes in designated time windows, as a function of the movement, and by extracting an image of defects, a filter which determines presumed defect zones and properties of these, a combiner to prepare working digital inputs from an extract of images of a defect zone, a neural circuit receiving the working inputs, a digital decision and alarm stage working on the basis of the output of the neural circuit, and a sorting and marking robot.
