摘要： 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.
