Abstract

The non-ferrous device would be able to slide over the pipe and be set in place. The squeeze ring or squeeze wedge type ring would be installed in an opening between the composite end ring and the pipe. Once in place the ring would be fixed in place between the end ring and the pipe. This device would allow that end to be stationary or anchored in the spot. The sealing device would then be slid onto the pipe and stop against the anchored end ring. The next end ring would be slid over the pipe and rest against the sealing device. Another squeeze ring or squeeze wedge type ring would be installed in that ring between the pipe and the end ring. This would anchor that end of the sealing device whereby all there piece are now locked in place. The pipe and the device can now be installed in the tubular string in an underground hydrocarbon or water well. The same device or multiple devices could be used in horizontal or vertical applications in casing, pipelines or openhole.

The purpose of this invention is to provide a method to attach one or multiple end rings to an isolation device like a down hole packer that would incorporate a squeeze ring or squeeze wedge type ring into the end ring and components thereof. This same design could be used on a center ring if there were multiple isolation devices installed on a pipe. The center ring version would have square shoulders on each or both sides, rather th...
