Abstract (en)

[origin: WO03025339A1] The invention relates to a device for cleaning an inner pipe inserted into a gas or oil conveying boring. This device comprises a hollow rod inside of which a pressurized medium can be conveyed and to which a cleaning device is connected in a fixed manner. The cleaning device has a rotatable head provided with cleaning nozzles (5), which are arranged diagonal to the longitudinal axis, with lateral, eccentrically oriented rotary nozzles (6), and with rinsing nozzles (12) extending diagonal to the cleaning nozzles (5) in the opposite direction. The inventive device is provided with redundant safeguards with which, in the event that the shaft breaks, moving parts of the nozzle head (1) and of the shaft (2) are prevented from detaching from a stationary outer sleeve (3) connected to the retaining rod whereby preventing parts from becoming lost.
