Casing Hangers

casing hanger (n.) – Mechanism that locks into the casing head, responsible for hanging the casing pipe.

Developed to last 20 years with proper maintenance, FMC’s casing hangers are available to fit a multitude of well environments. Slip hangers seal automatically or manually, depending on the types of seals integral to their installation.

Casing Hangers C21 Casing Hangers c24	C-21 & C-24 Designed with a “Type H” seal ring as a feature, these manual casing hangers are designed to use the seal as an additional packoff (which is independently installed) to provide an energized seal. These hangers fit standard FMC wellheads and can be lowered through the BOP before or after the cement has been set. With easily engaging, latching cap screws, the C-21 & 24 casing hangers are quick to install.

Casing Hangers C22 Casing Hangers C29	C-22 & C-29 Adaptable to all C-22 and C-29 casing heads, the C-22 slip hanger is designed to suspend average casing loads. This type of hanger provides automatic packoff sealing at only 50,000 pounds of casing load. It is also suitable for short casing or lightly loaded applications. Lowered through the BOP and landed either before or after the cement has set, the C-22 incorporates a spring-loaded latch, interlocking slips, and a heavy-duty hinge into its efficient design. The slips engage the casing evenly, thus distributing the casing load equally to the bowl of the casing head. Enhanced over time to become an industry standard, this hanger is available for off-the-shelf delivery.

Casing Hangers C121S	C-121S The C-121S casing hanger is made for a C-29 casing spool to hang heavy casing loads in potentially harsh environments. Difficult applications include high pressure, high temperature, or highly concentrated chlorides or H2S situations. With two options for packoff energization, this hanger can be used to meet a multitude of needs to suit your specific operation. Similar to our standard casing hanger product family, the C-121S has a split-bowl design with a compression packoff above the slips, and it incorporates locking slip segments with a non-extrusion plate.

Casing Hangers C129 Casing Hangers C122	C-122 & C-129 This line of casing hangers takes on a higher load capacity than our standard product line. When drilling in HP/HT environments, the C-122 & 129 slip hangers can provide additional features, like automatic packoff sealing. Compatible for use in C-22-EG, C-29, and C-29-ET casing spools, the C-122 and C-129 casing hangers use tangential bolting as a means of incorporating the split-bowl design. The patented non-extrusion plate further enhances the sealing capability of the hanger under both light and heavy casing loads, for a design life of up to 20 years.

Casing Hangers C229	C-229 Designed specifically to fit FMC’s C-29-ET casing heads and spools, the C-229 casing hanger handles extreme casing loads and pressures. Similar to the C-121S, the harsh environments for which the C-229 is suitable are high H2S, chlorides, and HP/HT. The automatic packoff sealing that comes from the extensively tested elastomer seals is located above the slips, and incorporates the split-bowl design.
