Abstract

A scraper for removing deposits from the exterior of a tubular member includes elements defining an outer jacket which has an inwardly open circumferential recess and two aligned axial openings, and 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 bend or geniculation. All geniculations are received within the recess, and each segment of wire extends generally along a chord of the aligned axial openings. The positions of the chords are distributed around the circumference of the axial openings such that, in order for the tubular member to be accommodated through the aligned openings, the various segments must be 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.
