An integral semi-flush connection designed for production casing, intermediate casing, tie-backs, and drilling and production liners.
Special applications include highly deviated and horizontal wells, drilling with casing, and where casing is rotated and pushed into place.
- Available in sizes from 7" to 16".
100% collapse rated thread seal created by full form contact of the dovetail threads, also providing a secondary internal pressure seal rated at pipe body.
High compression rating provided by the reverse angle stab flank of the threads makes the Wedge 523™ suitable for the more severe compression applications. Compression strength exceeds tension strength.
Wedge 523™ is interchangeable with Wedge 513™.
