2015 Casing Reference Tables World Oil®/JANUARY 2015 C–109 Dimension nomenclature D = Casing nominal OD of tube, in. W = Casing weight, lb/ft d = ID (drift), in. It is critical as it determines the strings size that we can run in a given casing. Nominal size: is the outside diameter of the pipe body. The most used sizes are: 2-⅜”, 2-⅞”, 3-½” and 4-½”. The tubing joint length: is the length of tubing joint including.

• Drilling, production and contingency liners
• Moderate depth production casing /slim hole designs
• Tiebacks in medium sizes
• ​Tight hole tubing strings in small sizes​.

• 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 tensio​n in medium wall thickness.
• The design of VAM® FJL™ exhibits an exceptional bending resistance for a connection of this class.
• Excellent gas tightness.

• Maximum clearance (100% flush)
• Easy to use and repair
• Only slight pin end swaging is needed for machining threads.​
