ABSTRACT:
A drill pipe protector is disclosed which provides a fluid-tight hydraulic seal between the protector and the drill pipe. The protector comprises a cylindrical body of an elastomer which is longitudinally split and encases a cylindrical and similarly split metal band. A sealing bead is formed along the periphery of the inside surface of the elastomeric body and along the longitudinal split therein. Under compression the sealing bead prevents fluids from entering between the drill pipe and the protector. In a preferred embodiment the metal band is concave and is adapted to receive a tapered locking pin which adjustably latches the protector into optimum frictional engagement with the drill pipe.
