ABSTRACT:
A pipe thread protector which provides a friction grip on the exterior of a threaded pipe section is disclosed. The protector includes an outer tapered shell with a pad of compressible material positioned in a recess in the interior side wall of the shell. A compression shaft in combination with a handle and cam device provides for compression of the pad so as to lock the protector to the pipe section. The particular configuration of the pipe thread protector of the present invention maintains the inside diameter of the pipe free from any obstruction throughout the length thereof, thus allowing the pipe to be drifted without obstruction. A quick release mechanism allows the protector to be easily removed when the pipe section is ready for installation on the job site.
