Optimised scraper for a conduit

摘要

A two-directional scraping device (1;25) intended for a fluid carrying pipe includes at least one thin disk (6) made of polymer stiffened by reinforcing means (8) secured to the disk. The disk, including the reinforcement, is divided into petals by at least two radial slots (11) whose length is smaller than the radius of the disk, the radius of the disk being substantially greater than the inside diameter of said pipe.
