API 5CT L80 casing is mainly used in oil wells as a well wall support to ensure the drilling process and the normal use of the entire oil well after completion.
L80-9Cr casing belongs to the corrosion-resistant casing steel group, especially suitable for CO2 environment. In a corrosive environment dominated by carbon dioxide, L80-9Cr shows high corrosion resistance. Compared with L80-1, L80-9Cr and L80-13Cr are both highly corrosion-resistant oil pipes, usually used in heavily corrosive oil wells.
API 5CT L80 special oil casing length usually starts with the letter R, divided into R1, R2, R3. According to API regulations, R-1 is 4.88~7.62m, R-2 is 7.62~10.36m, and R-3 is 10.36m to longer.
Usually, the product is bare. Thread type: usually divided into non-thickened (NUE), thickened (EUE), and special clearance (SCC).
