API 6D is a standard for pipeline valves formulated by the American Petroleum Institute (API). It is mainly used for the design and manufacturing of valves in long-distance pipelines, gathering and transportation pipelines, and related equipment in the oil and gas industries. This standard imposes strict requirements on the design, manufacturing, testing, and quality control of floating ball valves, aiming to ensure the reliability and safety of the valves under high pressure, high flow, and harsh environments.
