Abstract
A retractable cleaning apparatus for spray cleaning of pipes or vessels comprises a rotatable spray head configured to spray the interior of the pipes or vessels with a cleaning liquid. The rotatable spray head is linearly movable between a retracted position and a cleaning position along a longitudinal axis of the rotatable spray head. The rotatable spray head is rotatable about the longitudinal axis of the rotatable spray head independent of a flow of the cleaning liquid. The rotatable spray head is rotatable with an angular velocity that is independent of the flow of the cleaning liquid. The angular velocity may be within a range of 0.1-1.3 radians per second. A system including a retractable cleaning apparatus is also disclosed.
