API SPEC5CT-1999 (casing and tubing specification) is compiled and released by the American Petreleum Instiute (API), which is commonly used around the world. Among them: casing: a pipe that extends from the ground surface into the borehole as the lining of the shaft lining, and the pipe is connected through the hoop. The main materials are steel grade J55, N80, P110, and steel grade C90 and T95, which are resistant to H2S corrosion. Its low steel grade (J55, N80) can be welded steel pipe. Tubing: pipe that is inserted from the ground surface to the oil layer, and the pipes are connected through the hoop or the whole. Its function is that the pumping unit delivers the oil to the ground through the tubing. The main materials are J55, N80, P110, and C90, which are resistant to H2S corrosion.
