API 5CT CASING & TUBING
Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading API 5CT casing & tubing supplier
API 5CT is a standard established by the American Petroleum Institute (API) specifically for casing and tubing used in the oil and gas industry. Widely used in oil and gas drilling and extraction, it effectively protects wellbore integrity, preventing fluid leakage and contamination. This standard covers manufacturing, inspection, testing, and quality control requirements for seamless and welded steel pipes, ensuring sufficient strength and corrosion resistance for downhole applications in complex geological conditions and high-pressure environments.
API 5CT classifies products into distinct grades (such as J55, K55, N80, L80, P110), each corresponding to specific strength and chemical composition requirements tailored to diverse well applications. The standard specifies detailed technical parameters including pipe dimensions, wall thickness, surface finishes, and mechanical properties, guaranteeing product safety and reliability under high-pressure and harsh conditions.
Yantai Xinbaoshang's products consistently adhere to the API 5CT casing & tubing standard certification!
