Thread cleaning apparatus having adjustable diameter brush bases

摘要

An apparatus for cleaning of tubular threads having adjustable spacing brushes to accommodate tubulars of different diameters. A plurality of brushes are rotated in a drum, which fits over the tubular connection. The brushes are mounted on L-shaped brackets, which are in turn mounted to a rotary driver by a shaft extending through slots in the brackets. By loosening the attachment of the brackets on the rotary driver, the brackets can be slid radially inward or outward to the extent of the slots, thereby adjusting the diameter of the threads that can be cleaned. The front access plate and seal plate, through which the tubular extends into the drum, are preferably held to the drum by hand operable latches. Solvent may be injected into the drum and onto the threads by a hand pump, and captured in the drum and drained into a container for disposal or reuse.
