6 . API certification

API is the abbreviation of American Petroleum Institute, founded in 1919, the organization is based on the characteristics of the industry and its own needs. In 1924, the API specification was formulated to provide technical specification guidance for the production of related products in the petroleum industry. As the API specifications formulated by the API organization continue to expand due to their advanced nature, versatility, safety, and the influence of the US petroleum industry in the world, the API specifications have been widely adopted by countries around the world.

API standards mainly stipulate equipment performance, sometimes including design and process specifications. Standard formulation areas include petroleum production, refining, measurement, transportation, sales, safety and fire protection, environmental regulations, etc., and its information technology standards include EDI for the oil and gas industry. Communications and information technology applications.

API enjoys a high reputation in the United States and other countries in the world. It is a petroleum machinery certification body recognized by the US Department of Commerce and the US Trade Commission. The technical standards for petrochemical and oil extraction machinery developed by it are adopted by many countries. When oil companies in the Middle East, South America and many Asian countries bid for petroleum machinery, they generally require products with the API mark to be eligible to participate in the bidding. Therefore, petroleum machinery and equipment with the API mark is not only considered to be of reliable quality but also of advanced level. Only when products enter the international market can they be accepted and trusted by users.

7 . SIL Safety Integrity Level Certification

SIL (Safety Integrity Level)-safety integrity level.
