Next Generation Semi- Premium
Bushmaster® SP was designed to be the next generation’s semi-premium connection. It provides a solution to the issues plaguing API BTC compatible connections: limited torque, inconsistent makeup profiles, spinning couplings, poor sealability, and high connection stress. The Constrictor® thread form is tight fitting, providing an outstanding thread seal, reduces hoop stress to half that of an API BTC compatible connection, and generates extraordinary operating torque. This connection was built for the most challenging applications.
Negative load and stab flanks diminish the potential for jumpout and reduce localized movement within the connection under bending, tension, and pressure. Stepped crests and low pitch allow for Bushmaster® SP to be madeup in 6 turns compared to 12 for API BTC compatible connections. The coupling anti-rotation feature prevents spinning couplings in the field, reducing uncertainty and non-productive time. Bushmaster® SP saves operators money and time while holding up to the most challenging conditions.
- Hardwearing and extreme torque Constrictor® thread form
- Better sealability than API BTC compatible connections
- Low stress for low galling and performance in a corrosive environment
- Fast make-up to save operators valuable rig time
- Coupling anti-rotation feature to eliminate spinning couplings in the field
- Pin to pin torque stop combined with Constrictor® threads results in the highest class of rotating capability
The Constrictor™ thread form combined with a pin to pin torque stop provide rotating capability an order of magnitude greater than conventional semi-premiums. 5.500” x 23# P110 EYHC showed no signs of yielding even at 65,000 ft-lbs.
NEXT GENERATION THREAD FORM
Say goodbye to connection jumpout, slow makeup, 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 approximately half that of API BTC compatible connections, reducing susceptibility to galling and corrosion.
Pressure to failure indicates the pipe body fails mechanically before the connection
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.
