The API, which stands for the American Petroleum Institute, was created in 1919 as an organization tailored to the industry's characteristics and needs.In 1924, API specification was established to guide the production of oil industry related products.API specifications formulated by the API organization have been widely adopted by countries around the world due to their advanced nature, versatility, safety and the growing influence of the American oil industry in the world.

API standards mainly prescribe equipment performance and sometimes include design and process specifications. The standard formulation area includes petroleum production, refining, measurement, transportation, sales, safety and fire protection, environmental regulations, etc. Its information technology standards include EDI for oil and gas industry, communication and information technology application, etc.

API enjoys a high reputation in the United States and around the world. It is recognized by the U.S. department of commerce and the U.S. trade commission as a certification body for petroleum machinery.The technical standards of petrochemical and oil extraction machinery formulated by it have been adopted by many countries. When oil companies from many countries in the Middle East, South America and Asia bid for petroleum machinery, they generally require products bearing API marks to be eligible to participate in the bidding.Therefore, with the API logo of petroleum machinery equipment is not only considered to be reliable quality and advanced level, the product into the international market for users to accept and trust.

SIL (Safety Integrity Level) - Safety Integrity Level.

SIL technical standards were first promulgated and formulated by the international electrotechnical commission (IEC) and implemented centrally by IEC/TC65.The national technical committee on SIL technology is the national technical committee on process industrial measurement control and automation (SAC/TC124), and the secretariat is the institute of comprehensive technical and economic research of instruments and instruments for the mechanical industry.

The SIL certification is divided into four levels: SIL1, SIL2, SIL3 and SIL4, including the product and system levels, among which SIL4 has the highest requirements.

API 607 and API 6FA are fire resistance tests for valve 6D and 6A. Generally, only a 6D valve rotating 90° needs to be done API 607, while others need to be done API 6FA.PAI is short for American petroleum institute,6FA is a kind of fire protection certification for 6A standard valve fire test, and a 607 fire protection certification for 6D standard valve fire test
