THREADED CONNECTOR LOCKING DEVICE

摘要

A system (10) for joining pipe segments, the system (10) including a first pipe connector (12) connected to a first pipe segment, and a second pipe connector (14) threadingly connectable to the first pipe connector (12), and connected to a second pipe segment. The system (10) further includes a recess (28) in the outer surface of the first pipe connector (12), and an elongated key (16) having first and second lengthwise surfaces (22, 24). One of the lengthwise surfaces (22, 24) has protrusions (26) that embed into a transverse surface of the second pipe connector (14) when the key (16) is mounted into the recess (28). The thickness of the key (16) decreases with distance radially inward from the outer surface.
