API 5CT L80 Casing and Tubing 

API 5CT is a standard specification for casing and tubing used in the oil and gas industry. It specifies the technical delivery conditions for steel pipes, including requirements for chemical composition, mechanical properties, manufacturing processes, and testing procedures. The standard covers various grades of steel pipes, including H40, J55, K55, N80, L80, C90, T95, P110, Q125, and V150, and is widely used in the exploration and production of oil and gas. API 5CT is developed by the American Petroleum Institute (API) and is recognized globally as a standard for casing and tubing.
