Abstract: A key assembly is press fit into an annular space between a box and pin member to resist relative rotation of the box and pin members. The key assembly includes wedge like members that contact one another along complementary tapered surfaces, and when in contact generate radial forces into the box and pin member to secure the connection between the box and pin. The outer wedge is inserted first into the annular space between the box and pin members, and has rows of elongate teeth that project radially outward into contact with an inner surface of the box member. Because the outer wedge is pushed radially outward against the box member rather than axially sliding therebetween, the teeth protrude into the surface of the box member thereby increasing the anti-rotation force created by the outer wedge.

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

Abstract: A pipe connection includes a pin having external threads and a box having internal threads. A circumferentially extending row of pin teeth are located on an exterior portion of the pin. A slot extends through a side wall of the box. A key is carried in the slot, the key having a row of key teeth that mate with the pin teeth. The key is mounted to the box such that a movable portion of the key is radially movable relative to the box between radially outward and radially inward positions. The key is biased toward the inward position, so that the key teeth ratchet on the pin teeth during make-up of the pin and the box. The key and pin teeth have a saw-tooth configuration to resist unscrewing rotation of the pin and the box. The key may be an integral part of the side wall of the box or a separate component.
