VAM® FJLTM (Flush Joint Liner) is a 100% inside and outside flush integral connection providing maximum clearance with optimum strength for liners, moderate depth casing, and tight-hole tubing strings.
APPLICABLE RANGE
- Available in sizes from 2 3 /8″ to 11 7/8″
- Yield strengths from 80 ksi to 140 ksi
- Standard, alternative and special drifts
- Carbon, Martensitic stainless steel (13%Cr & Super 13%Cr) and Nickel base Alloys.
APPLICATIONS
- Drilling, production and contingency liners
- Moderate depth production casing /slim hole designs
- Tiebacks in medium sizes
- Tight hole tubing strings in small sizes.
PERFORMANCE
- 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 class.
- Excellent gas tightness.
BENEFITS
- Maximum clearance (100% flush)
- Easy to use and repair
- Only slight pin end swaging is needed for machining threads.
