Abstract
Jet pipes of this type are used in particular for processing contaminated earth. High costs for the exchangeable parts result from wear and the period of inoperation. The object is to design the jet pipe in such a way that the periods of inoperation are reduced and the wear lessened. The jet pipe (1) has an inlet (2), a section (3) adjoining the latter and having outlet openings arranged about the inside of the tube in the circumferential direction, and a conical tube section (5) adjoining the section (3). The conical tube section (5) is designed as a tube insert which can be inserted separately from the section (3). <IMAGE>
