SSX-A liner hanger, designed with double cones, double cylinders and double-row slips, is hydraulically set by applying pressure through the run-in string. After brass ball is dropped to ball seat in landing collar, high pressure fluid acts on piston inside cylinder and move slips upward to set position.
1. Be set hydraulically, suitable for shallow and medium-depth wells.
2. The dual-cone and dual-cylinder structure allows higher hanging capacity and higher hanger setting success ratio. Liner weight is distributed onto the internal wall of the previous casing more evenly.
3. Working with ball-setting carrier, suitable for horizontal and highly-deviated wells.
4. Sealing element is made from nitrile/fluorine rubber, rating temperature 120℃/200℃.
5. Main parts are made with high-strength alloy steel providing high burst/collapse resistance.
6. Setting tool can be easily released just by slacking off certain weight and using right hand rotation.
7. Retrievable pack-off bushing can be retrieved with setting tool, avoid drill-out.
