A Modern Semi-Premium
Hercules® was designed to be this generation’s semi-premium connection. It provides a solution to the issues plaguing API BTC compatible connections: inconsistent makeup profiles, spinning couplings, poor sealability, and high connection stress. The patent pending PrecisionFit® hooked thread form is tight fitting. It provides an outstanding thread seal while allowing for half the hoop stress of an API BTC compatible connection. Corrosive environments are where this product shines. Its negative load flank diminishes the potential for jumpout and reduces localized movement within the connection under bending and tension. Stepped crests and low pitch allow for Hercules® to be madeup in 7 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. We can customize the Hercules® connection to meet the demands of your specific application. Contact us to learn more.
- Patent pending PrecisionFit™ hooked 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
- Breakthrough barrel nose design to maximize torque capabilit
The unique barrel nose design of Hercules™ provide a significantly larger torque stop compared conventional semi-premiums.
NEXT GENERATION THREAD FORM
Patent pending PrecisionFit™ hooked thread form diminishes the potential for jumpout, provides incredible sealability, and reduces coupling stress.
Low thread pitch, stepped crests, consistent makeup profile, and coupling anti-rotation 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
NEGATIVE LOAD FLANK
The negative load flank of the PrecisionFit™ thread form prevents sliding of the thread under tension and minimizes hoop stress under load. Positive load flank connections have increased hoop stress due to sliding under tension.
