JFETIGERTM 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 loads. The negative load flank thread form and coupled design provide 100% tension efficiency for the standard coupling.
Special clearance coupling OD’s are available with full pipe body internal and external pressure ratings.
|Reduced gap between stabbing flanks on the pipe and coupling thread.||⇒||Increased resistance to damage from compressive loads.|
|Negative load flank angle on threads.||⇒||Increased tensile and bending capacity while maintaining gas tight seal.|
|25° angle for thread stabbing flank.||⇒||Quick make up and increased resistance to cross threading.|
|Different corner radius for load flanks for pipe and coupling threads.||⇒||Increased resistance to galling.|
