TYPE BC-21, BC-22 AND BC-29 CASING HANGERS
The BC-22 casing hanger combines packoff, slip bowl, and slips into a single unit.The packoff automatically seals when casing load is applied,thus allowing annulus packoff before removing blowout preventer and cutting casing.This wraparound hanger is easy to install.Simple construction and few parts make the BC-22 easy and economicalto repair,and the individual tapered slip bowl reduces casing head repairs.
The BC-21 casing hanger consists of slips, slip bowl, and a floating seal ring (type H packoff).Slips and slip bowl can easily be wrapped around the casing. The seal ring slips over the casing and into the casing head after casing has been suspended and cut off, providing a positive annulus packoff.
