Description

Specialty semi-premium connection machined from heavy-wall coupling stock and forged blanks. The GB 3P Connection performances exceed that of standard API connections. Connection designed with 3-Pitch threadform for easy-stabbing, fast makeup without cross-threading. Pin noses engage shoulders in the coupling center for positive indication of proper field makeup. Pin noses, designed for maximum bearing face area, provide high torque resistance.

Features

  • Uses GB 3P threads.
  • Easy-stabbing, fast makeup without cross-threading.
  • Meets API Coupling OD and Drift Diameter Specifications.
  • Field proven in a variety of static and dynamic applications.
  • Excellent make/break repeatability under field conditions.
  • Enhanced fatigue life.
  • Can be inspected with standard API Thread Gauges by any properly trained/experienced Third Party (special setting standards required).
  • Positive makeup indication with pin nose/shoulder engagement in center of connection. Also, has API Triangle Stamp on Pin for secondary makeup verification.
  • Innovative Triple Taper Design reduces localized bearing stresses for enhanced fatigue resistance and reduced galling potential.
  • Heavy cross-section at center of coupling provides hoop stability for enhanced leak resistance and reduced jump-out potential.
  • High Torque resistance.
  • Drive-able.

Available

  • Casing sizes 16" OD to 20" OD.
  • All API Casing Grades and 16" OD through 20" OD Line Pipe; Grades X-56 and X-80.
