Abstract (en)
[origin: WO2004042314A1] The invention relates to a system for cleaning bundled-tube heat-exchanger tubes, whereby cleaning bodies run through the tubes (5) and are discharged from the tubes (5). Said cleaning bodies (la-1h) are embodied such as to be temperature-resistant, resistant to aggressive flow media, to be transported in flowing media, to sink or float in still media, to run through the tubes (5), by means of the pressure of the flowing media and to press the contact surface thereof against the inner surface of the tubes with a contact pressure.
