ABSTRACT:
The present invention provides a device for cleaning tubes, in particular the internal surfaces of tubes in heat exchange systems. The device comprises a mass (2) with an optionally provided central through-hole (10) disposed thereon, and optionally provided a plurality of protrusions (20, 21) mounted and/or moulded on the mass (2). The through-hole (10) is preferably of a conical shape-like configuration. A plurality of first protrusions (20) is disposed in a fin-like arrangement on the mass (2). A plurality of second protrusions (21) is disposed in a spiral arrangement on the mass (2), and the lengths of the second protrusions (21) are relatively longer than the length of the first protrusions (20). The mass may consist of an asymmetrically positioned weighted core (15) of different weights and sizes to provide a variety of relative density to the device and to serve as a geometrical manipulation to impart rotational momentum and random dynamic motion to the device.
