ABSTRACT:
A pipe thread protector for use in protecting the threaded ends of a pipe against damage prior to the time the threaded ends of the pipe are engaged with the ends of other lengths of pipe. The pipe thread protector is formed of a resilient material and has a cup-shaped body which overlies the pipe threads to be protected. The outermost portion of the body is formed with threads complementary to the pipe threads. Inwardly of the protector body threads, the protector body is formed with a plurality of tapered wedging ribs. These wedging ribs automatically center the body of the protector upon the pipe end as the protector is urged over the pipe end for subsequent engagement of the protector threads with the pipe end threads. The wedging ribs thereafter frictionally restrain the protector against rotation relative to the pipe end.
