Particularly hard encrustations in pipelines, which often consist mainly of calcium carbonate, can be removed by a striking mechanism of a pipe cleaning device and by additional cleaning tools of the same, in which, in specific specially designed bores of counter-rotating turbines of the cleaning head, which also has a hollow axis for fluid longitudinally at the front, striking pins strike outwards at the encrustations such as boiler scale within the pipeline and, with a similar arrangement and function, also operated by fluid, steel brushes can additionally be employed by means of a cleaning head in the pipeline to remove such encrustations. <IMAGE>
