When using the Hydraulic Running Tool, neither rotation nor reciprocation of the liner is needed for setting. However, the liner can be reciprocated during cementing without the need to modify the equipment. Should hydraulic pressure fail to actuate the Running Tool, the Simplex Liner Hanger can be set mechanically while in the hole. This ensures the liner can be hung in tension without leaving it on bottom.

The liner Hanger is actuated by dropping a ball that seats on the Landing Collar with Shear-out Sub, Product No. BI 266-52. Applied pressure will cause the piston in the Liner Hanger setting tool to move upward and release the spring loaded slips. Liner weight is placed on the Simplex Liner Hanger by downward movement of the work string. Application of an adjustable predetermined pressure will clear the fluid path in the Landing Collar for cementing. Right-hand rotation of 12 to 16 turns will release the setting tool from the hanger.

Three basic sizes of Hydraulic Running Tools will fit all Simplex Liner Hangers run inside 5" through 13-3/8" OD casing. A minimal parts change is required to fit the Hydraulic Running Tools to the various Liner Hanger sizes.

Features

Adjustable Setting Pressure - Setting pressure may be adjusted by selection of shear screws used in the Hydraulic Running Tool and Landing Collar with shear out Sub.

Mechanical Set Backup - In the event of an emergency, the hanger may be set by right-hand rotation of the Hydraulic Running Tool. This enables the slips to be released from the slip-pockets to engage the ID of the casing and hang the liner.
