Casing Heads

The casing head housing is the lowest part of the wellhead assembly and is almost always connected to the surface casing string. It supports subsequent drilling wellhead and completion equipment

C-22 Casing Head

The C-22 Casing Heads have a straight bore bowl design which avoids damage to sealing areas by drilling tools and prevents test plug and bowl protector wedging problems when pressure is applied. This straight bore design also reduces maintenance costs and permits suspension of heavy casing loads.

C-22 Casing Heads are normally furnished with two inch threaded outlets but optional sizes and studded outlets are available upon request. Bottom connections can be furnished threaded or slip-on welding.

C-29 Casing Head

The C-29 straight bore casing heads are based on the same reliable design as the C-22 with exception that the bowl is two inches longer, which permits the acceptance of the minimum-deflection C-29 Casing Hanger.

Test Plugs, Bowl Protectors, Retrieving tools are available for use in the C-22 and C-29 Casing Heads. The Bowl Protector minimizes wear in the casing head bore caused by rotating drill pipe. Test Plugs allow testing of the BOP and connections above the casing head.
