API 5CT L80-9Cr 13Cr oil casing can be identified by the steel grade represented by its color, for example, the color of L80-9Cr is represented by one red, one brown, and two yellow. This identification method helps to quickly identify the material and performance of the casing on site, ensuring the correctness and safety of use.
L80-9Cr 13Cr Oil Tubing Pipe belongs to the corrosion-resistant casing steel group, among which L80-9Cr and L80-13Cr are suitable for CO2 environment. L80-9Cr and L80-13Cr are both highly corrosion-resistant oil pipes, usually used in heavily corrosive oil wells.
