Abstract: In a system for cleaning tubes of tube-bundle type heat exchangers including a plurality of tubes (5) arranged in parallel between two chambers (10a, 10b) and flown through by a fluid medium, in particular crude oil, at a temperature above 120° C., wherein, for cleaning the tubes (5), deposits on their inner walls, such as coking, dirt particles or the like, are detached by cleaning bodies passing through the tubes (5), and carried out of the tubes (5), for cleaning the inner wall of the plurality of tubes (5) of the heat exchanger during the operation of the heat exchanger (10), it is provided that the cleaning bodies (1a–1h) are formed in such a way that they are resistant to high temperatures (above 120° C.
