Abstract: A jaw assembly for gripping tubular goods in a power tong. The jaw assembly has at least three (3) jaw members: a first primary jaw member, a second primary jaw member, and at least one intermediate jaw member disposed between the first and second primary jaw members. The jaw assembly can be easily and conveniently installed within a conventional 2-jaw power tong without extensive modification thereto, and increases the pipe gripping capacity of the tong (and particularly small size pipe) without damaging the pipe.

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.
