MC-21 CASING HANGER AND TYPE H SEAL
It is a cylindrical-profile, single-slip casing hanger, housed in either MC-22 or MCM casing heads or casing spools. It is used together with type H seals to isolate the annulus space, regardless of the casing load on the hanger. It cannot be used when the head has tie-down screws (MC-22P or MC-29P casing heads or casing spools) or with BX rings.

MC-22 CASING HANGER
It is a cylindrical-profile, single-slip casing hanger, housed in either MC-22, MC-29 or MCM casing heads or casing spools. It is a wrap-around, integral slip and seal assembly that can be lowered through the preventors. The annulus seal is automatically energized by the weight of the casing.

MC-29 CASING HANGER
It is a cylindrical-profile, dual-slip casing hanger, housed in either MC-29 or MCM casing heads or casing spools. It is a wrap-around, integral slip and seal assembly that can be lowered through the preventors. The annulus seal is automatically energized by the weight of the casing. It has a high load capacity and distributes the loads in order to minimize tubing deflection.
