ABSTRACT:
A jet pipe comprises a housing having a suction inlet for the medium to be taken in and an outlet, a conical tubular portion following the suction inlet towards the outlet and a section adjacent to the suction inlet provided with discharge openings arranged peripherally around the tubular interior for a discharge of a highly pressurized medium. When such jet pipes are used for processing contaminated soil, the wear of the individual parts of the jet pipe causes high expenses and non-productive time. In order to reduce wear and non-productive time, the section comprising the outlet openings is formed as a replaceable ring.
