ABSTRACT:
A cleaning device, or projectile, cleans the inside surface of a tube as it is propelled by a liquid through the tube by mechanically scraping and cleaning soft and hard deposits, such as sludge and manganese, from the inner surface of the tube, such as those found in condensers and heat exchangers. The tube cleaning device, or projectile, is propelled forward by a high-pressure fluid spray injected into a tube. This high-pressured fluid injection is sufficient to advance the device through the tube, allowing the device to scrape or otherwise dislodge incrustations or other accumulations from the interior wall of the tube. The tool cleans the inside surface of a tube as the tool travels through the tube and includes a compressible bushing and a series of cutters secured to a split support that defines a cavity for receiving the bushing, the support being adapted to be opened and closed to receive and contain the bushing. Each cutter defines a cutting surface of a diameter that depends on the diameter and hardness of the bushing. Use of bushings with various diameters and hardness provides effective cutting surfaces of various diameters and scraping forces of various magnitudes. Each cutter can define a mounting groove to receive a metal cutter for tougher deposits.
