API 5CT Grade L80 Steel Oil Casing Pipe

The CASING head is an important connecting piece between casing and wellhead equipment, which is used for the connection between casings of each layer, between casing and BOP, and for the support and connection between the well completion and the production (gas) wellhead Tubing Pup Joint.
Its lower end is connected with surface casing through thread, and its upper end is connected with wellhead equipment or BOP through flange or clamp. The hanger supports the weight of the casing in the subsequent layers, bears the weight of the BOP, forms a pressure seal between the inner and outer casings, provides an outlet for releasing the pressure between the casing strings, and can perform special operations in drilling and production technology Pup Join.

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.

It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow

drilling fluid to circulate and extraction to take place
