ABSTRACT:
A scraper for removing deposits from the exterior of a tubular member which has a plurality of concatenated, resilient segments adapted to contact the exterior surface of the tubular member where each pair of adjacent segments is connected through a geniculation. The resilient segments are aligned with and interposed between a pair of opposing annular disks that are connected together by a plurality of spacers located adjacent to the outer periphery of the disks and adjacent to the chords of the segments. The chords of the segments are distributed around the circumference of the axial openings such that the various segments are deformed outwardly, whereby the resilience of the thus deformed segment urges it inwardly against the tubular member, and causes it to clean the tubular member as the scraper moves axially.
