VAM® HTTC
VAM® HTTC is the most advanced T&C design in the VAM® product family. Thanks to its optimized self-locking, dovetail thread concept, it combines running reliability, ultra-high torque capacity and ample bending margin, while always ensuring the highest sealability performances. The entire product line is validated against API RP 5C5:2017 / ISO 13679:2019 CAL-IV, including at MTS (Maximum Torque with Sealability).
Performances
- Internal pressure rating: 100% pipe body
- Collapse rating: 100% API 5C3 (or HC)
- Tension capacity: 100% pipe body with sealability
- Compression capacity: 80% pipe body with sealability (and structural resistance to 100% pipe body)
- Bending capacity up to 42°/100 ft under combined loads
- Gas sealability validated as per API RP 5C5:2017 / ISO 13679:2019 CAL-IV, including at Maximum Torque with Sealability (MTS)
- Simple, reliable and easy running (running practices similar to standard premium connections)
- Recess-free bore as a standard feature for all sizes
