6. API certification
API is the abbreviation of American Petroleum Institute. It was founded in 1919. The organization is based on the characteristics of the industry and its own needs. In 1924, API specifications were formulated to provide technical specifications guidance for the production of related products in the petroleum industry. Because the API specifications formulated by the API organization are continuously expanding due to their advanced nature, versatility, security, and the growing influence of the US petroleum industry worldwide, API specifications have been widely adopted by countries around the world.
API standards mainly stipulate the performance of equipment, sometimes including design and process specifications. The standards setting areas include petroleum production, oil 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 petrochemical and oil extraction machinery technical standards were developed by it have been adopted by many countries. When oil companies in the Middle East, South America and Asia bid for petroleum machinery, they generally require products bearing the API mark to be eligible to participate in the bidding. Therefore, petroleum machinery equipment with API mark is not only considered to be of reliable quality but also of advanced level, and products are accepted and trusted by users when they enter the international market.
