ABSTRACT:
A liner hanger for use in an oil well completion comprising a hanger assembly which can be passed through a tubular pipe and has a continuous bypass and a shaped area for passing through fluid and cuttings in the pipe. The hanger assembly has an inclined cam surface which is spirally disposed along the length of a hanger body. A one-piece, heat treated, slip device comprised of strip of metal having an internal spiral and inclined cam surface is disposed up on the spiral cam surface on the hanger body. The spiral space around the hanger body provides a shaped bypass area. The spiral slip device is attached to setting means. Upon release of the setting means, relative movement between the slip device and the cam surface on the hanger body permits the slip device to be positioned in setting engagement with the inner wall of a tubular pipe.
