GC-22 Series Casing Heads and Spools

Economy and versatility were the reasons for creation of this medium to deep hole application equipment. GC-22 casing heads and spools are available for all pressure ranges in size 11” and above. The internal configuration of the GC-22 casing head and spool are designed to accept the GC-21 manual casing hanger and type GCP primary or type GC-22 automatic casing hanger. Annulus sealing is casing load activated in the GC-22 automatic casing hanger. Line pipe thread, studded or extended flanged side outlets are typically furnished on this series of casing housings, however, other outlet preparation is available. The type GC-22 casing spool is usually machined to accept the type GLS stack-on type secondary seal assembly and type FF bit pilot, although internally suspended secondary seal assemblies are available. Lower flanges of type GC-22 casing spools are supplied with a test port, complete with internal ball check valve, and bleed port to facilitate testing of primary and secondary seals. Supplementary bore protectors, test plugs, wear bushings and test plug assemblies are available for this line of housings. Many sizes and pressure ratings other than those posted below, including crossovers in the case of spools, are available.

GC-22 and GC-21 Casing Hangers and  GCP Primary Seal Assemblies

The type GC-22 automatic casing hanger, designed for use in type GC-22 casing heads and spools, is suitable for most casing string loads. The GC-22 automatic casing hanger is hinged for easy installation around the casing and is comprised of an outer slip bowl, internally guided slips and a sealing element that is energized by slip loading. Although economical, the GC-22 is an efficient performer.

The GC-21 manual casing hanger provides an economical method of casing suspension and is recommended for medium depth applications. The GC-21 manual casing hanger is also designed for use in type GC-22 casing heads and spools. It consists of an outer slip bowl, internally guided slips and is hinged for easy installation around the casing. Together with the type GCP primary seal assembly, the GC-21 provides an economical means of casing suspension and annulus seal in a straight bore configuration type GC-22 casing housing. Many other sizes are available.
