VetcoGray RL-2HCX
The RL-2HCX pre-loaded, high strength threaded connectors are the strongest connectors available for applications requiring high bending and fatigue capabilities since 2003. The RL-3HCX connector features two-start threads that provide make-up of less than one turn of the suspended pipe. Anti-rotation keys are installed at the pin and box interface to provide additional torque resistance.
Features & Benefits
- Available up to 36" for high bending and fatigue applications, two thread start for rig time savings through 7/8 to 1-1/2 turn fast make-up
- High stab angle with dual stab guides, negative back rack thread angle to reduce belling, and self aligning thread profile for easy rig run, positive stop load shoulder to serve as the visual indication for proper connection make-up
- Pre-loaded for strength, rigidity, and good fatigue characteristics (36,000-40,000 ft-lbs)
- High anti-rotation resistance torque to ensure reliable make-up with four anti-rotation keys, each key 48,000 ft-lbs
- Drivable, releasable, reusable
- Dual seal option for full thread isolation to keep out sea water for a longer fatigue life
- Optional lip seal eliminates bleed port requirement to ensure holding pressure
- Large radius fillets and stress relief grooves for improved fatigue
