ABSTRACT:
A thread protector for the external threads of a pipe comprises two parts, an outer sleeve and an inner casing having spaced arcuate sections. The arcuate sections have threads thereon conforming to the pipe threads, a flange at their outer end having raised bosses around its inner periphery, and a shoulder around its other end. The outer sleeve is axially matable with the casing, having a lip at its outer end and a channel about its other end. The two parts are axially secured to the threaded pipe and locked thereon by interaction of the casing and sleeve so that the unit is removable from the threaded pipe only by unscrewing the same as a unit.
