Integral Flush Design
. The O.D. and I.D. are 100% flush (there is no upset). The I.D. is bored and recess-free for smooth, efficient flow. The O.D. is turned to tight tolerances.
Multiple Seal System
. This multiple seal arrangement ensures gas-tight sealing integrity to 100% of the rated burst and collapse of the pipe body.
Interference Tapered Thread
. Thread load flank has a 15° reverse angle to resist jump out. Thread stabbing flank has a 45° angle for fast, trouble-free make-up.
In order to provide optimum strength, the VAM
FJL is designed for 65% to 70% efficiency under tension in medium wall thickness.
The design of VAM
FJL exhibits an exceptional bending resistance for a connection of this
xcellent gas tightness.
Maximum clearance (100% flush)
Easy to use and repair
Only slight pin end swaging is needed for machining threads.
