JFETIGER™ has been designed and tested to meet the needs for critical well loads. The design incorporates metal-to-metal seals with a 17° internal torque shoulder to ensure sealing under extreme loans. The negative load frank thread form and coupled design provide 100% tensile efficiency for the standard coupling.
Special clearance coupling OD’s are available with full pipe body internal and external pressure ratings.
| Design | Advantage | |
|---|---|---|
| Reduced gap between stabbing flanks on pipe & coupling thread | ➡ | Increased resistance to damage from compressive loads |
| Negative load flank angle on threads | ➡ | Increased tensile & bending capacity while maintaining tight gas seal |
| 25° angle for thread stabbing flank | ➡ | Quick make up and increased resistance to cross threading |
| Different corner radius for load flanks for pipe & coupling threads | ➡ | Increased resistane to galling |
