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.

Abstract: A thread protector has a toroidal body of elastomer with a bore to accept a pipe end and a metal band and clamp arrangement extending around its periphery. The body is cut through one side to allow the body to expand peripherally. The bore accepts the end of a pipe with threads to be protected when the periphery is expanded and grips the pipe with the bore when the clamp closes the cut and shrinks the bore. To increase unit loading to force more elastomer of the body into thread grooves the bore has projections for gripping pads, or is recessed radially to produce gripping pads. The pads, which may be replaceably attached, reduced area increases deformity under clamping pressure and increases the force required to dislodge the protector from threads. The metal band is removable from an open peripheral groove or an optional arcuate tunnel partially encircling the pad body.
