The liner hanger is equipped with single hydraulic cylinder and single-row cones. The liner hanger is hydraulic-set and the packer weight-set.


Features of SSX-A Hydraulic Liner Hanger

  • The main parts of the line hanger are made of high-strength alloy steel, which ensures high mechanical performance and strong ability to hang heavy liner.

  • The liner hanger is hydraulic-set and applicable to various well conditions.

  • All of the pump-down plug, liner wiper plug and the landing collar have locking systems and are easily drillable.

  • The pack-off bushing can be pulled out with the setting tool and therefore saves time for drilling out.

  • The seal assembly contains a set of "W" packing rings that have perfect two-direction sealing capacity.

  • The gage rings on the liner hanger not only serve as rigid centralizers, but also protect the hydraulic cylinder and slips while running in.

  • To release the setting tool from the liner, simply apply 5 to 10 t load to the drill string and rotate right hand.
