API 5CT Steel Pipe Description
API 5CT is a standard technical specification of steel pipes for casing and tubing in oil or gas industries. It can be used in oil or gas drilling and conveying. Commonly used oilfield API-5CT casing steel grades are J55, K55, N80-1, N80Q, P110. Casings are mostly used in oil well drilling. According to the API-5CT standard, pipes can be divided into STC (short thread), LTC (long thread) and BTC (support thread) and their joints.
