ABSTRACT:
An apparatus for cleaning an annulus (13) formed between two generally concentric pipes (11, 12) includes a cleaning head (14) carried by feed tubes (15, 16) which position the head (14) at selected vertical positions within the annulus (13). The feed tubes (15, 16) carry fluid under pressure to the head (14). A valve (40) controls which of the feed tubes (15, 16) is receiving fluid under pressure. When valve (40) provides fluid through the tube (16), fluid is emitted through nozzles (18, 22, 25) in the head (14) to move the head (14) in one direction around the annulus (13) and clean the annulus (13). When valve (40) alternatingly provides fluid through the tube (15), fluid is emitted through nozzles (31, 32, 33) in the head (14) to move the head (14) in an opposite direction around the annulus (13). The head (14) may be simultaneously moved vertically within the annulus (13).
