Abstract: A technique facilitates use of a liner hanger in a wide variety of environments by distributing loading. The liner hanger may comprise a liner hanger cone, e.g. an annular cone body, having a plurality of slots for receiving corresponding pipe-gripping slips. The slip slots and the corresponding pipe-gripping slips are staggered both longitudinally and circumferentially to distribute loading. An actuator may be used to shift the slips into gripping engagement with a surrounding pipe, e.g. casing, to improve the load distribution on the surrounding pipe and liner hanger cone once the liner is supported.

Abstract: A technique facilitates actuation and use of a liner hanger in a wide variety of environments. Depending on the application, the liner hanger may be conveyed downhole within a casing located in a wellbore. The liner hanger comprises slips which may be set against the casing by applying a pressurized fluid through a liner hanger port to a liner hanger actuator. After the slips are set, the liner hanger may be actuated to form a metal-to-metal seal which blocks further fluid flow through the port, thus isolating the port during subsequent downhole operations.

Abstract: A technique facilitates hanging of a liner in a borehole. According to the technique, a liner hanger and a liner may be deployed downhole into a borehole. A wellbore anchoring device of the liner hanger is initially actuated to engage a surrounding surface and to resist downward movement of the liner. Additionally, a hold down anchor is subsequently actuated to resist upward movement of the liner. The hold down anchor may be released via mechanical manipulation of the liner hanger.

Abstract: A technique facilitates joining of sections of tubing and related monitoring. An expandable tubular member may be coupled with an external tubing, e.g. a casing. The expandable tubular member is deployed into the external tubing to a desired position. Then, an expandable portion of the expandable tubular member may be plastically deformed in a radially outward direction and into engagement with the external tubing. A sensor system may be combined with the expandable tubular member to monitor a characteristic of the expandable tubular member.

Abstract: A valve assembly for a fuel injector that includes a sleeve member having an interior chamber, a piston member supported for movement within the interior chamber of the sleeve member and separating an upstream pressure side of the valve assembly from a downstream pressure side of the valve assembly, and a dynamic sealing device mounted to one of the sleeve member and the piston member for sealingly isolating the upstream pressure side of the valve assembly from the downstream pressure side of the valve assembly. The dynamic sealing assembly includes a PTFE seal member having a generally C-shaped cross-section defining an internal cavity having an opening about the outer periphery thereof the seal member, and a helical spring disposed within the internal cavity of the seal member for providing a constant sealing force to the seal member.
