  • Publication number: 20220090725
    Abstract: A centralizer for centrally locating measuring/testing equipment within the interior of a pipeline while traveling through the pipeline includes a first flange structure and a second flange structure nominally spaced from the first flange structure along the direction of travel of the centralizer. A plurality of radially outwardly curved loops extending between the first and second flange structures to form curved arches that define an outwardly convex outer surface. One or more ridges, or a single or a plurality of wheels, extending along the loops to project outwardly of the outer surfaces of the arches to extend above the remainder of the outer surface of the arches to bear against the interior of the pipeline.
