API 5CT N80 Casing and Tubing 

API 5CT L80 casing and tubing are types of steel pipes used in the oil and gas industry for drilling and completion operations. The L80 designation refers to the steel grade and mechanical properties of the pipe, including its yield strength, tensile strength, and hardness. L80 casing and tubing are commonly used in wells with moderate to high pressure and sour environments, where corrosion resistance and toughness are critical. They are available in various sizes, lengths, and connections, and are manufactured according to the API 5CT specification, which sets standards for the design, manufacturing, and testing of oil country tubular goods (OCTG).
