Abstract
A method for manufacturing a centralizer assembly includes reducing a diameter of a mandrel such that a turned-down region is formed in the mandrel, positioning a first stop segment in the turned-down region, and positioning a centralizer at least partially in the turned-down region, wherein the first stop segment is positioned intermediate of axial extents of the centralizer, such that the first stop segment at least partially limits a range of motion of the centralizer relative to the mandrel.
