Abstract
A tubular cleaning tool can be delivered through tubing and then hydraulically or mechanically actuated to rotate blades about respective pivot location into approximately a 45 degree orientation for commencement of tool rotation and cleaning a larger tubular that is below. Each of the blades has a cantilevered distal end that further features at least one articulated link. The outer periphery of the articulated distal segment has hard facing to enhance the cleaning effect and to reduce blade wear. The remainder of the blade outer surface can also have hard facing for similar reasons. The distal segment can be biased toward the surrounding tubular when the blades extend to put the segment in the needed orientation for cleaning.
