ABSTRACT:
A pipe thread cleaner has cleaning heads with rotated thread brushes driven by motors on the heads. Separate heads for box and pin ends have splash shrouds with gaskets to bear on pipe surfaces. Cleaning fluids under pressure are supplied, selectively, to the heads. The heads have a scavenger system plumbed to a vacuum collector tank. The heads have pipe bore plugs on brush spindle extensions that seal the bore and squeegee the inner pipe surfaces when the heads are removed from the pipe. Optionally, compressed air replaces cleaning fluid to jets in the heads to finally blow dry the cleaned threads. Further options include jets that spin with the brushes and a centrifuge to recover reusable cleaning fluids from the effluent fluids from the cleaning heads.
