Product Description
API is an acronym for the American Petroleum Institute and is considered the most authoritative and comprehensive principle in the oil and gas industry. API 5B and API 5CT are mainly used for oil casing. API 5CT oil casing can be divided into seamless steel pipe and welded steel pipe. 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.
