Pipe thread protector

摘要

The pipe thread protector is a capped pipe that is adapted for use with a pipe and is designed to protect the interior screw threading and the exterior screw threading formed on the end of a pipe. The capped pipe is placed over the end of the pipe. The capped pipe is held in position with a plurality of cantilever springs that extend from the center of the capped pipe and that fit into the center space of the pipe to be protected. Once the plurality of cantilever springs are placed in the center space of the pipe to be protected, the plurality of cantilever springs press against the side of the pipe to hold the pipe thread protector in position. The pipe thread protector comprises an interior thread protector and an exterior thread protector.
