The UMD-104M device for testing reusable oil-well tubing

The optimal structural scheme and special features of a new automated device for the magnetic flaw detection of seamless pipes and electric-welded oil-well tubing in the process of their production and recovery of used pipes are considered. It is shown that the application of state-of-the-art technologies for manufacturing single-chip thin-filmed high-resolution matrix transducers substantially increases the functional capabilities of a flaw detector and not only ensures the reliable detection of all inadmissible flaws, such as discontinuities in metal, the wear of pipe walls, and displacement of the edges of a welded seam, but also provides higher reliability indices of sensors (breakdowns are minimal).
