The C-22 / C-29 Casing Spool are a straight bore bowl with 45° landing shoulder design. Bottom preparation can be the PE/BG as in the picture，“OO” bottom ( for below 5000 psi application) or double “P” seal bottom. The BG preparation allows the use of reducer bushings “PE” (Pressure Energized). Outlets are normally threaded; optional studded / flanged outlets are available.
C-29 Casing Spools are based on the same reliable design as the C-22 with exception that the bowl is longer. This permits the acceptance of the C-29 casing hanger with larger load capacity for deeper drilling.
