Anaconda™ GT

Next Generation Premium Semi-Flush

Anaconda™ GT is the next generation of premium, semiflush connections. Its seat-optimized seal delivers premium sealability with burst and collapse ratings equal to pipe body. The Constrictor™ thread form provides outstanding operating torque without the need for a traditional shoulder, minimizing the risk of an ID restriction. Negative load and stab flanks lock the pin and
box together for performance under combined loading. A box OD only 3-5% larger than pipe body provides clearance when its required. Anaconda™ GT is ready for the most demanding applications. Its been field proven in high pressure gas wells with as many as 100 fracture stages, served in sour environments, and given operators the torsional capacity to TD tortuous wells with long laterals. Stepped crests and low pitch allow for makeup is as few as 5 turns. Makeup is fast and consistent, allowing operators to save valuable rig time. Anaconda™ GT was built to tackle both the technical and economic challenges facing the oil and gas operators of this generation and the next.

Anaconda™ GT


  • Heavy duty and extreme torque Constrictor® thread form
  • 90% efficiency under tension and compression
  • Near flush OD and true flush ID for maximum clearance
  • Seat-optimized seal provides 100% burst and collapse rating
  • Low stress for reduced galling and performance in a corrosive environment
  • Fast make-up to save operators valuable rig time


The Constrictor™ thread form provides a significantly larger torque area compared conventional semi-flush connections.


Say goodbye to connection jumpout, slow running speeds, and galled threads. The Constrictor™ thread form was developed for the next generation of OCTG demands.


Low thread pitch, stepped crests, consistent makeup profile, and variable width threads reduce nonproductive time and significantly increase running speed.


Hoop stress at makeup is less than half that of API BTC compatible connections, reducing susceptibility to galling and corrosion.


Negative load and stab flanks lock the pin and box together radially, providing outstanding pressure integrity.


The Constrictor™ thread form prevents sliding of the thread under tension, compression, and bending and minimizes hoop stress under load. This provides an ideal stress profile and the ultimate connection integrity.
