Key Features
- Metal‑to‑metal seal designed to be stronger than the pipe body & proven to be +100 % gas tight through deviated wells
- Flush inside diameter enables easy lining operations
- Optimized groove & lining assembly that does not sacrifice tension or internal pressure
- Slimmer connection O.D. than an API coupling
- Integral connection design reduces leak paths compared to API & eliminates coupling based running issues
