VetcoGray RL-4F
The RL-4F pre-loaded, high strength connector has a flush outside diameter for jetting, driving, and drilling applications and has been used since 1995. The RL-4F connector features four start threads which provide make-up with only 1/4 to 1/2 turn of the suspended pipe. An anti-rotation key is installed at the pin and box interface to provide additional torque resistance with 32 to 48 kip-ft.
Features & Benefits
- Flush OD available 22"~24" for jetting/driving close clearance
- Self locking four start threadform for rig time savings through 1/4 to 1/2 turn fast make-up
- High stab angle with dual stab guides 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 high fatigue tolerance. Good driving efficiency
- Anti-rotation feature resists 40,000ft-lbs torque above connector make-up torque
- Dual seal version is available to trap a corrosion inhibitor in the trades, extending the fatigue life of the connector.
