Oil and gas well casing

Carbon steel Pipe API 5CT J55 K55 N80 L80 high quality Casing oil and gas well CASING

Classification of TUBING
Tubing is divided into non thickened tubing (NU), thickened tubing (EU) and integral joint tubing. The non thickened oil pipe refers to that the pipe end is directly threaded and equipped with coupling without being thickened. Thickened tubing means that the two pipe ends are externally thickened, then threaded and equipped with couplings. Integral joint oil pipe refers to that one end passes through internal thickening external thread, and the other end passes through external thickening internal thread, and is directly connected without coupling.

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
