ABSTRACT:
Disclosed is an apparatus for cleaning the interior of elongated tubular objects such as pipes, tubes, etc., using a reciprocating lance having a cleaning fluid spray head at its end. Fluid pressure provides reciprocating movement to the lance. The cleaning fluid pressure is independent of the fluid which provides movement to the lance, thereby maintaining the desired fluid pressure to the nozzle through the complete cycle of reciprocation.
