ABSTRACT:
A system for cleaning both the box and pin ends of tubular members, recovery of the fluid residue, filtering of the residue to recover the heavy solids, and disposing of each of the components of the residue in an environmentally safe manner. A first housing positionable over the end of a tubular member; a first bladder expandable from the housing to seal around the outer wall of the tubular member; a plurality of jets positioned adjacent the threads of the tubular member, so that as the jets are rotated around the threads, a high pressure fluid spray cleans the threads of the member; a second bladder expandable from the end of the jetting means for sealing the inner bore of the member beyond the threads, so that all fluid jetted into the housing from the jetting nozzles is captured within the housing and flows from the housing, and no fluid flows beyond the threaded pipe end either along the inner or outer walls of the tubular member. The fluid is then collected, filtered, and the filtrate is disposed as wastewater, and the filters containing the filtered solid is placed in environmentally safe sealed containers for disposal.
