Refrac Connections for Well Re-Completion
LFS FJ-HT®
U.S. Patent 10,774,959
Canadian Patent 3,093,607
- Optimized tensile-compression-ratio connection with a modified square thread profile for efficient load transmission.
- High torque, true-flush joint connection.
- Steep taper combined with course thread to reduce turns to shoulder & improve make-up time.
- Cylindrical run-in and run-out threads for maximum potentially higher connection strength.
- Tapered internal & external shoulders strengthening the connection during over torque or compression situations.
