Flanged Casing Heads / Casing Spools - KBF type

Casing Spools - KBF type

This casing head has flanges at the bottom and the top and between them a casing hanger to hold the well’s casing string, and the interim casing string’s secondary sealing system, as well as the guide bush. Depending on the casing hanger’s type the flanged casing head’s bore may be cylindrical or tapered. The cylindrical bore type casing hanger sits over a 45 ° shoulder. The two side connectors of the flanged casing head have API 1/2” LP, API 2” LP, or API 2 1/2” LP threads; the connectors are with threaded studs and with sealing rings, depending on the size and pressure rating of the gate valve or of the threaded flange (2 1/16”, 2 9/16” or 3 1/8”).

In the bottom flange, there is a tapered valve and a housing plasticizer through which the secondary sealing element(s) may be plasticized by using „P-seal”. Also in the bottom flange, there is a ball valve used to check the pressure developing inside the sealing ring, to monitor the sealing efficiency in the ring space (annulus).

Additional sizes are available upon request.
