Abstract: A device for checkivng steel pipes during production and to a method using the device. The device includes a station for acquiring measurement data representative of physical measurements of the geometry of a pipe taken on an outside thereof, and a computer system configured to store template data applicable in a coordinate system and representative of overall geometry of a sizing body. In a chosen coordinate system, the system then provides a three-dimensional representation of parts of the pipe. For each part of the pipe, the system is referenced to determine a critical parameter, representative of the margin of passage of the sizing body inside a chosen part of the pipe. The method and device may thus establish a diagnostic of traversability of the pipe by a sizing body.

Abstract: Device forming an operating tool, for the non-destructive testing of iron and steel products, intended to extract information on possible imperfections in the product, from feedback signals that are captured by transmitting ultrasound sensors, receiving ultrasound sensors forming an arrangement with a selected geometry, assembled to couple in an ultrasound way with the product via the intermediary of a liquid medium, with relative rotation/translation movement between the pipe and the arrangement of transducers, said operating tool being characterized in that it comprises: a converter (891; 892) capable of selectively isolating a digital representation of possible echoes in designated time windows, as a function of the relative rotation/translation movement, said representation comprising the amplitude and time of flight of at least one echo, and of generating a parallelepipedic 3D graph, a transformer unit (930) capable of generating a 3D image (901; 902) of possible imperfections in the pipe from the 3D gra
