- Twin cantilever design reinforces the coupling, creates high contact
pressure (leak resistance) in mating threads, limits expansion and
distortion from make-up, reduces assembly pre-stresses, and minimizes
thread galling.
- Interchange-able with standard API Buttress Connections - eliminates
cross-overs and special accessories, such as float shoes and collars.
- Inspect with standard API and MRP gauges and procedures.
- Makes up to an internal torque shoulder and has API triangle stamp
for secondary make-up verification.
- 100% joint efficient under all load combinations. Will not jump
out (or in) in high angle build sections common in directional drilling.
- Independent physical testing demonstrates the connection is gas
tight.
- Maintains pressure integrity when special clearance.
- Meets API drift and OD specifications.
Options
-
Special Clearance OD (SC): Specify GB Butt SC when ordering. See
Data Sheets for minimum special clearance OD and associated properties.
-
Modified (MOD): Specify GB Butt MOD when ordering. Includes grooved
couplings with seal rings.
