ABSTRACT:
A pipe-thread protector which includes a molded plastic drum-shaped body and a solid metal band encircling the body. The body has a corrugated outer circumferential wall, a concentric inner wall spaced from the outer wall, and a corrugated web joining the two walls at one end. An end wall is joined to the inner wall. The other end of the outer wall carries an integral ring. The inside of the outer wall has lengthwise ribs which have internal screw threads. The space between the walls forms an annular pocket for receiving the end portion of a pipe, while the internal threads engage the pipe threads and the ring snugly receives the pipe beyond the threads.
