Casing spools are a very important component in controlling wellhead pressure. They are often flange ended on the top of the casing head and connected with the bottom of the tubing head, ultimately comprising a portion of the wellhead system.
Casing Spools Equipment
A casing spool has a straight bore bowl with 45°landing shoulder that prevents damages to sealing areas commonly caused by drilling tools. This also eliminates test plug and bowl protector wedging problems when pressure is applied. Casing spools are normally furnished with threaded outlets and studded outlets and can also be manufactured by request. They can be used for single completions and models of dual completions.
