Model HC-E Tie Back Seal Nipple with Packer

Features

 

1. Run with casing or casing plus drill pipe. Used for the tie-back

 

of a liner string to surface or to any position above the liner top.

 

The packer is set after cementation.

 

2. A solid expandable mechanism is incorporated into the packer

 

system to hold 10,000 psi differential pressure.

 

3. Once the packer is set, the hold-down slips and the internal locking

 

mechanism hold the packer tight. Neither picking up nor slacking

 

off the drill string can retrieve the packer.

 

4. Specially designed spring sleeve prevents prematured setting of the packer.
