Abstract:
For the removal of deposits from the exterior of a tubular member, a scraper comprising:an outer jacket defining an inwardly open circumferential recess and two aligned axial openings, a scraper element in the form of an elongate resilient wire bent to define a series of integral, concatenated, resilient segments, each pair of adjacent segments being connected through a geniculation, the geniculations being received within said recess with at least one segment extending substantially along a chord of the aligned axial openings, whereby, in order to accommodate the tubular member through said aligned axial openings, the tubular member must deform said at least one segment outwardly, so that the resilience of the deformed segment urges it inwardly against the tubular member and causes it to clean the tubular member as the scraper moves axially relative to the tubular member.
