Optimized scraper for a conduit

The invention relates to a two-directional scraper intended for fluid carrying pipes. The invention is notably well-suited to withstand both chemical attack and abrasion. When the same pipe is used for successively delivering different fluids, it is well-known to use scraper plugs to separate the fluids while cleaning the walls of the pipe. These scrapers can also be displaced all along the pipe in order to remove, at regular intervals, the deposits that may have formed on the inner walls. A two-directional scraping device () intended for a fluid carrying pipe includes at least one thin disk () made of polymer stiffened by reinforcing means () secured to the disk. The disk, including the reinforcement, is divided into petals by at least two radial slots () 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.
