ABSTRACT:
A rotary tube cleaning system having a rotary cutting tool attached to an elongated flexible drive wire for remotely cleaning the inside of elongated tubes, and method for its use. The tube cleaning system includes a special rotary cutting tool rigidly attached to an elongated flexible drive wire, which are rotatably driven through a slip clutch by variable speed rotary drive means. The tool has dual oppositely-facing cutting edges at its forward end and also has dual longitudinally separated cylindrical guide surfaces provided at the tool forward and rear ends. In the method for remotely cleaning the tubes using the rotating cutting tool, the tool is inserted into a thimble tube, rotated at 150-250 rpm and fed forward at 5-20 ft/min to cut or scrape any deposits from the inner wall of the tube. The tool is then removed and similarly inserted into other tubes in sequence to scrape and substantially remove accumulated material therein.
