Range: 3-1/2” 16’’ / 89 406 mm

Unique Feature

  • Patented ULTRA thread form
  • Patented locking center-shoulder seal
  • Strongest semi-flush connection
  • Connection diameter approximately 3 – 5% greater than pipe body

Thread Profile

  • ULTRA full contact thread form provides high connection efficiency
  • Run-in and Runout threads maximize critical cross-sectional area
  • Close fitting thread minimizes movement within the connection and transfer of load onto the seal and shoulder under compression
  • Thread root and crest are parallel to the pipe axis which results in easy stabbing
  • Optimized thread profile offers greater number of full threads for improved mechanical integrity under combined loads
  • Reduced cross threading
  • Increased bending capacity

Locking Center-Shoulder Metal-to-Metal Seal

  • Optimized seal design for increased connection sealability envelope
  • Two sealing surfaces for redundancy
  • Retains connection driftability even when over-torqued
  • Increased torque capacity
