The C-22 / C-29 Casing Heads have a straight bore bowl with 45° landing shoulder design which avoids damage to sealing areas by drilling tools and prevents test plug and bowl protector wedging problems when pressure is applied.

C-22 / C-29 Casing Heads are normally furnished with threaded outlets and studded outlets are available upon request. Bottom connections can be furnished threaded or slip-on for welding.

C-29 Casing Heads are based on the same reliable design as the C-22 with exception that the bowl is longer, C-22 which permits the acceptance of the C-29 casing hanger with larger load capacity for deeper drilling.
