Hydraulic Liner Hanger

 

 

Nasr Mobtakeran manufactures a complete line of tools for setting and cementing liners over a wide range of depths, weights and sizes. Our equipment has been used around the world on some of the deepest and most difficult wells, on “state-of-the-art” horizontal completions, in deepwater applications, and on less challenging wells where the customer simply wanted the most reliable completion equipment available.

 

Hanger is available with either casing or heavy-wall tubing construction; "casing body" hanger cone pads are welded to the tool body, while "solid body" hangers include these parts as integral features machined from the heavy-wall tool body, eliminating body welding and maximizing performance.

The casing body hanger is manufactured from L-80 and P-110 casing grades, with other grades available by special order. A full body OD permits matching of some premium threads on the hanger body. Solid body hangers are

 

machined from AISI 4100 series alloy steel with controlled yield strengths and hardness for liner compatibility; 80,000 psi through 125,000 psi minimum yield strengths are standard with other materials available by special order. Solid body hanger dimensions are matched for compatibility with all current premium connections.

 

 

Mechanical Liner Hanger

Mechanical-set Liner Hangers are set through manipulation of the work string; quarter-turn right-hand rotation aligns the cones and slips, after which slack off sets the slips into the casing wall. The Hanger is available with either casing or heavy-wall tubing construction; "casing body" hanger cone pads, lug, and gauge rings are welded to the tool body. "Solid body" hangers include these parts as integral features machined from the heavy-wall tool body, eliminating body welding and maximizing performance.

 

 

The casing body hanger is manufactured from L-80 and P-110 casing grades with other grades available by special order. A full body OD permits the matching of some premium threads on the hanger body.

Nasr Mobtakeran Liner Hangers are set by picking up on the liner and rotating to disengage the J-slot. As the liner is lowered, springs hold
the cage stationary. This allows the barrel to move downward engaging the cone against the slips. This action moves the slips outward against the casing wall.
