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

- Validated under ISO 13679 CAL IV
