S-22 Casing Heads and Spools
Printable
Version
The Seaboard conventional wellhead system incorporates the S-22 straight bowl design with a 45 degree load shoulder.

Significant advantages of the S-22 bowl:
- One bowl design that universally accepts slip-type or mandrel casing hangers
- Low-weight hangers for tieback applications and high capacity hangers are also accommodated due to the straight bowl and 45 degree load shoulder which diminishes hoop stress on the casing heads and spools
- Design concept is carried forward into the Fas-Loc and SMB-22 multibowl systems for component interchangeability and retention of superior design characteristics
- Damage during drilling activities is minimized, thereby decreasing the frequency of maintenance and/or potential replacement
- Wear bushings can enhance the protection of important sealing surfaces
- Test plugs and wear bushings often wedge in tapered bowls under pressure, a possibility virtually eliminated with the S-22 bowl design
