ABSTRACT:
A new and improved casing thread protector that has a toroidal body of elastomer with a bore to accept a pipe end, thread engagement pads, and a metal band and clamp arrangement extending around its periphery. The bore accepts the end of a pipe with threads to be protected when the thread engagement pads are allowed a certain degree of movement due to the open position of the clamp, which pads subsequently grip the pipe within the bore when the clamp is closed. The pads, which are replaceable, come into contact with the tubular inserted in the bore when the clamp is in the closed position, isolating the tubular good from the body of the improved device and creating greater pressure on the contact points of the threads of the tubular good which increases the force required to dislodge the improved protector from the threads. The band and clamp arrangement may be placed in an open peripheral groove which creates an optional arcuate tunnel partially encircling the outer face of the body member of the new and improved casing thread protector.
