High Performance 15000PSI Casing Head for Oil and Gas Drilling
Product Introduction
The casing head is a component connecting the casing and various wellhead devices. To support the gravity of the technical casing and reservoir casing, to seal the annular space between each casing, to provide a transition connection for the installation of upper wellhead devices such as bop, tubing head and tree, and through the two side openings in the casing head body, to perform the cementing, monitoring well sinking, and injection balancing operations.
Casing head spool is a simple metal flange welded or screwed onto the top of the conductor pipe (also known as drive-pipe) or the casing and forms part of the wellhead system for the well.
The casing head options are:
A. The lower part of the casing head can be the API standard round thread casing master connection or API standard partial trapeziform casing thread master connection, or the plug-in type casing connection or the slip type casing connection.
B. Welded support chassis can be provided.
