  • Apparatus for automatically measuring external and internal profile of a pipe at the end thereof
    Patent number: 7310890
    Abstract: An apparatus for automatically measuring the internal and external profile of pipes (1) at the ends thereof is described, wherein sensors (11a, 11b) measure for each angle of rotation of their support (10) the distance of the corresponding profile, there being provided means for regulating in height the axis of rotation of said support, which is rotatably mounted on a slide (13) slidable in a direction parallel to the axis (X-X) of the pipe to be measured. The measuring system also comprises the processing of the detected data in order to attribute a classification code to the end of the measured pipe.
