API 5CT is standard technical specifications for steel casing and tubing pipes used for oil wells in petroleum and natural gas industries. Besides casing and tubing, it also includes pup joints, coupling stock, coupling material, and accessory materials, and establishes requirements for three product specification levels (PSL-1, PSL-2, and PSL-3).
The steel grades of joint oilfield API-5CT casing include J55, K55, N80-1, N80Q, and P110. To understand API CSG grades, it is essential to understand the terms minimum yield stress, maximum yield stress, and minimum ultimate strength. To explain these terms, we will use two popular grades of oilfield tubulars as an example: L-80 and …
