GH Series Casing Heads and Spools

The GH series casing heads and spools have been designed for shallow to medium depth wells where working pressures above 5,000 psi are not anticipated. This series of housings have a tapered bore design which acts as a supporting surface for the fully loaded casing hanger. The GH casing head housing has an upper bore internal configuration which will accept either the GH manual casing hanger and the GHP primary seal assembly, or the GH-2 automatic casing hanger/packoff assembly. The GH casing head is usually furnished with female threaded or slip-on weld lower connections, however, other connections are available on a special order basis. 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 GH spool is prepared with an internal preparation which accepts the snap-ring retained type GAC integral bit pilot/secondary seal assembly. Lower flanges of type GH casing spools are equipped with test and bleed ports to facilitate testing of primary and secondary seals. This series of casing suspension housings combine practicality and durability into an extremely cost efficient package.

GH and GH-2 Casing Hangers and  GHP Primary Seal Assembly

The GH-2 automatic casing hanger is designed for use in type GH casing head and spool housings. It combines the hanger section and the primary sealing medium into a unitized assembly. Upon installation of the GH-2 casing hanger, annulus pack-off is automatically achieved; as GH-2 automatic casing hangers are designed for load activated positive sealing. Should you desire additional assurance, the GHP primary seal assembly can also be installed as a supplementary seal, when the type GH-2 automatic casing hanger is employed.

The GH manual casing hanger is a simple wrap-around hanger designed for use in the GH casing head housing, and is engineered for use with the type GHP primary sealing medium. Purposefully designed for medium casing load applications; the type GH casing hanger, when utilized together with the type GHP primary sealing medium, offers positive annulus pack-off and casing suspension in an extremely cost efficient package.
