Exploitation assist tool forming device for non destructive control of tube, has filters determining presumed imperfection zones and properties of each zone in images, and output stage generating conformity/non conformity signal of product

摘要

The device has converters (891, 892) for selectively isolating a digital representation of echoes in time windows based on relative rotation/translation movement and generating a three dimensional (3D) graph, where the representation comprises amplitude and time of flight of echo. A transformation block (930) generates 3D images (901, 902) of imperfections in a product i.e. tube, from the graph and a database. Filters (921, 922) determine presumed imperfection zones and properties of each presumed zone in the images. An output stage generates a conformity/non conformity signal of the product. An independent claim is also included for a method for non destructive control of siderurgy products e.g. tubes, during fabrication or at finished state.
