AN APPARATUS FOR DETERMINING THE RADIAL PROFILE OF A PIPE AND A METHOD FOR OPERATING SAME

摘要

Apparatus and method for determining the axial profile of at least a first or second pipe (4, 6) for oil field use, wherein a sensor tip (292) is biased against the first or second pipe (4, 6) and where a linear sensor (292) is designed to give a signal that reflects the change in radial dimension as the first or second pipe (4, 6) and the sensor tip (292) are moved relative each other with at least one motion component in the axial direction of the first or second pipe (4, 6).
