API 5DP DRILL PIPE
Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading API 5DP drill pipe supplier
API 5DP is a standard specification for drill pipe established by the American Petroleum Institute (API), primarily used in the global petroleum and natural gas industries for transmission pipelines. DRILL PIPE plays a critical role during drilling operations, connecting the drill bit to surface equipment while transmitting rotational power and circulating drilling fluid. This standard covers manufacturing, inspection, testing, and quality control requirements for seamless and welded steel pipes, ensuring the safety and reliability of drill pipe under high-pressure and extreme environmental conditions.
API 5DP standard classifies products into distinct grades (E-75, X-95, G-105, S-135), each corresponding to specific mechanical properties and chemical compositions. This enables smooth drilling operations across diverse geological conditions. The standard specifies detailed technical requirements for pipe dimensions, wall thickness, surface treatment, and fatigue resistance, ensuring excellent wear and corrosion resistance in high-stress, high-pressure environments.
Yantai Xinbaoshang's products consistently adhere to the API 5DP drill pipe standard certification!
