For hanger retention, the heads can be configured with external thread (ET) lock screws.

Casing Head

• For low to medium casing loads, the heads can be configured with the C-22 bowl profile accepting all C-21 and C-22 style slip hangers.
• For heavier or more extreme casing string loads, the heads can be equipped with a C-29 bowl allowing all slip hanger options to be used.
• Installation is quick and straightforward using either individual running and retrieving tools or combination tools that also allow BOP testing.
• The C-22 and C-29 style heads and spools are practical and offer our customers a robust and economical means of drilling wells onshore or offshore.

Casing Spool

• The C-22 Elastomer Groove (EG) profile eliminates the need to lockdown screws to retain the bowl protector.
• This profile is also common for the C-22 casing heads.
• The bottom preparation accepts a variety of secondary elastomer or metal to metal seals to achieve annular seal integrity.
