Valveworks USA casing hangers are combined in a single unit that incorporates packoff, slip bowl, and slips.
C-22 and C-29 casing hangers provide automatic packoff sealing by energizing the seal when the string weight is applied.
When the casing load is suspended on C-22 and C-29 casing hangers, the packoff automatically seals the casing annulus below the slips, providing annulus packoff before removal of the blowout preventer (BOP) and cutting the casing.
*A Type H Primary Plate is required to achieve annulus seal on C-21 casing hangers.
Valveworks USA casing hanger’s controlled friction reduces casing deflection and provides excellent hanging capacity. *See above for specific capacities.
The casing load is distributed equally to the bowl of the casing head due to even engagement of the slips.
Note: To maintain an equally distributed casing load, the slip segments may require adjustment prior to the string weight being applied.
