Product Introduction
Liner Hanger is a tool/system that is used to hang a liner in a production well. Liner is similar to casing, but it is not run through the full depth of the well, as casing is. Key reasons of using liners are: • Open hole is cased off faster • Less weight for a wellhead • Better cementing • Rig capacity • Cost advantage over a full casing string


1. Mechanical Liner Hanger

The SSX-A Mechanical Liner Hanger, with double cones, double-row slips and double cylinders, is set hydraulically by applying pressure through the run-in string. A setting ball is circulated or dropped to the ball seat built into the landing collar. Applied pressure pushes slips up the cone to the set position.

1,Mechanical liner hanger is set hydraulically, applicable to different wells, especially to deep wells.

2,With two different setting mechanisms, the SSX-A can set easily.

3,Working with SQ setting-ball carrier, the DYX-C is suitable for applications in horizontal or highly-deviated wells.

4,The piston sealing element is made of nitrile/fluorine rubber for higher pressure and temperature ratings.

5,Main parts are fabricated with high-strength alloy steel providing high burst/collapse resistance.

2. Hydraulic Liner Hanger

The DYX-C is hdraulically set by applying pressure through the run-in string.A setting ball is circulated or dropped to a ball seat built into the landing collar.Applied pressure acts on the internal piston and moves slips up the cone to the set position.

1. The DYX-C is to be set hydraulically, which is designed for applications in all types of wells.

2. Working with SQ setting-ball carrier,the DYX-C is suitable for applications in horizontal or highly-deviated wells.

3. The piston sealing element is made of nitrile/fluorine rubber for high pressure and temperature ratings.

4. Main parts are fabricated with high-strength alloy steel providing high burst/collapse resistance.
