摘要

The method involves moving a cleaning nozzle (14) in a corrugated pipe (10) in a relative manner. The cleaning nozzle is provided with spray orifices (12), where cleaning agent is sprayed by using pressurized air. The air is directed and passed inside the corrugated pipe against the relative movement. The cleaning agent is filtered and returned back to a reservoir after use. An independent claim is also included for a cleaning apparatus for internal cleaning of corrugated pipes.
