Wellhead Equipments
Wellhead is a device that is attached to the casing to suspend the strings and sealing of the well wall. This equipment is adopted for the connection of tubings and casings to an oil or gas pipeline. These casings are pipes which are permanently installed in the well hole to contain pressure and prevent collapse.
Casing Head
The casing head serves as an equipment used in connecting the casing with the wellhead. The top and bottom part is made up of API 6A flanges which contain locking bolts. The casing head is furnished with a straight bore bowl with 45 C landing shoulder to prevent certain damages that could occur when excess pressure is applied.
Casing Spool
This is the button part of the wellhead that’s often connected to the casing string on the surface of the well. It facilitates the suspension and packing of the next casing string; provides annular outlets, and also supports the BOP during the drilling process.
Tubing Heads
This is practically the topmost spool in the wellhead formation. This equipment is attached to the casing spool so as to properly hang the tubing and conceal the annulus In between the casing and its tubing.
