The present invention is one for providing an apparatus and a method which make it possible to remove a foreign object or matter such as scale attached on an inner surface of a pipe easily for a short period of time by means of simple equipment and manner, and constituted as follows. Specifically, a holder (11) is attached onto an end of a pipe (P), an abrasion assisting member (16) fixed to a tip end of a support arm (15) is inserted into the pipe (P) by use of the holder (11) and stopped at an area (A) where oxide scale (S) is generated in a large amount. Then abrasive is sent with pressure into the pipe (P) by a blast device (14), and thus a flow rate of the abrasive in the scale-abraded area (A) is increased to abrade and remove the oxide scale (S) securely. Moreover, if required, a spiral groove (17) is formed on an outer circumference of the abrasion assisting member (16) to increase centrifugal force of the abrasive.

L'invention concerne un dispositif et un procédé de suppression de corps étrangers, permettant de supprimer facilement des corps étrangers, tels que le tartre adhérent à la surface intérieure d'une conduite, dans un temps très court, par le biais d'une installation ou d'un procédé simple. Un support (11) est monté sur l'extrémité d'une conduite (P) et un élément secondaire de meulage (16), fixé sur l'extrémité avant d'un bras de support (15), est inséré dans la conduite (P), en faisant appel au support (11), jusqu'à son arrêt dans une zone (A), dans laquelle la couche d'oxydes (S) se forme en grandes quantités, et jusqu'à ce que des abrasifs soient alimentés sous pression dans la conduite (P) par un système de soufflage (14), permettant ainsi d'augmenter le débit des abrasifs dans la zone de meulage de tartre (A), pour atteindre un meulage et une suppression fiables de la couche d'oxydes (S). En outre, si nécessaire, une rainure spiralée (17) est formée dans la périphérie extérieure de l'élément secondaire de meulage (16) pour produire un écoulement rotatif, permettant d'augmenter la force centrifuge sur les abrasifs.
