Conventional Gas Lift Mandrels

Starting at $310.00

Conventional gas lift mandrels are installed as part of the tubing string and have an exterior ported lug that will accept either a 1 in [25.4 mm] or 1 ¬Ω in [38.1 mm] OD conventional surface control device and a reverse-flow check valve. These mandrels are internally drifted to standard drift specifications and hydro-statically tested to 6,000 psi [41,370 kPa].

 

Conventional mandrels

Conventional mandrels are designed for single-string installations and are normally used in injection-pressure-operated tubing flow applications.

 

B & C deflector lug mandrels

Deflector lug mandrels are designed for dual-string installation and are normally used in injection-pressure-operated tubing flow applications. These mandrels feature long, tapered lugs that are welded in-line with the exterior ported lug. The lugs protect the installed subsurface control device and allow the mandrel to easily pass other mandrels during installation in dual string applications.

 

BR & CR deflector lug mandrels

BR & CR deflector lug mandrels are designed for either single-string or dual-string installations and are normally used in production-pressure-operated tubing flow applications. Like B & C deflector lug mandrels, BR & CR deflector lug mandrels feature long, tapered, welded-on lugs for use in dual-string installations.

 

The exterior ported lug on the BR & CR deflector lug mandrels is located near the middle of the mandrels and is called a capsule lug. The surface control device is installed into the top of the capsule lug, and the reverse flow check valve is installed into the bottom of the capsule lug. Two O-rings in the lug create a seal above the holes in the device. These holes expose the bellows to production pressure.
