Since valves are used in multiple applications throughout the residential, commercial and industrial industries. They are extremely beneficial that several major regulatory organizations provide standards to ensure compatibility, functionality, and safety for users. Among those organizations, the major standard organization is the American Petroleum Institute (API). Being the China API valve manufacturer, the main emphasis is given on test requirements, inspection, and examination.
The API represents the natural gas and oil industry. It produces more than 900 standards, as the basis for quality programs, for the maintenance of the regulations of lubricants, pressure vessels, storage tanks, certification programs, and piping inspectors.
China API valve manufacturer is highly influenced by the API standard so we are following this standard in a manner that is applicable to be used in multiple applications. This is used by people both, nationally and internationally. Effectiveness and speed are ensured.
Many reports are published by API including research reports, environmental and valves procedures, and specifications on pipelines.
API 692: This standard covers the least amount of dry gas sealing system requirements.
API SPEC 6D: This is an adoption of ISO 14313: 1999 for natural gas and petroleum industries. This standard specification gives recommendations for plug valves, gate, and check, documentation of the ball, testing, manufacturing and design applications in pipeline systems.
API STD 598: This is for testing and valve inspection. This covers pressure test, supplementary examination, and inspection that covers both metal-to-metal seated and resilient seated butterfly, check, ball, plug, globe and gate valves.
API STD 527: This describes the methods to determine seat tightness of soft and metal seated pressure relief valves. This also includes pilot-operated, bellows and conventional designs.
API STD 603: This is included for the measurement of sizes for check valves, globe, and steel.
API STD 607: It’s a fire test for valves that are equipped with non-metallic seats and doe quarter-turn valves.
API STD 594: This covers pressure-temperature ratings, face-to-face dimensions, materials, and designs. Test requirements, inspection, and examinations are also done for bronze, iron, nickel-based alloys and special alloys like butterfly valves (covers the category of butterfly valve A & B).
