API is the abbreviation of American Petroleum Institute. It is a U.S. petroleum industry organization that provides important weekly data on U.S. oil consumption and inventory levels.
An important task of API is to be responsible for the standardization of equipment used in the oil and gas industry to ensure the safety, reliability and interchangeability of equipment used in the industry. The formulation of coordinated standards is one of the earliest and most successful API projects. Since the first standard was released in 1924, API has published 500 standards. API is an ANSI-approved standard-setting organization. Its standard formulation follows ANSI's coordination and formulation procedures guidelines. API also formulates and publishes standards jointly with ASTM. In addition, API actively participates in the formulation of ISO standards suitable for global industries. It is ISO/TC671SC9 Secretariat of wellhead equipment and pipeline valves.
API standards are widely used. They are not only adopted by enterprises in China, but also cited by U.S. federal and state laws and regulations, as well as by the Department of Transportation, Department of Defense, Occupational Safety and Health Administration, U.S. Customs, Environmental Protection Agency, U.S. Geological Survey and other government agencies. It is also quoted by ISO, International Legal Metrology Organization and more than 100 national standards worldwide.
API standards mainly specify equipment performance, and sometimes include design and process specifications. Standard formulation 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 pipeline steel pipe
API line pipe is a line pipe that belongs to the American petroleum standard. The line pipe transports the oil, gas, and water extracted from the ground to the oil and natural gas industrial enterprises through the line pipe. Line pipes include seamless pipes and welded steel pipes. The pipe ends have flat ends, threaded ends and socket ends; the connection methods are end welding, coupling connection, socket connection, etc.
Pipeline steel pipe material: L245, L360, A53, J55, N80, X42, X46, X52, X56, X60, X65, X70
Specification of pipeline steel pipe: ∮60-630×1.53-40
API issued the APl5L standard in 1926, which initially only included three steel grades A25, A, and B, with minimum yield values of 172, 207, and 241MPa respectively.
API 5L seamless steel pipe is pipeline steel seamless steel pipe-API 5L pipeline steel seamless steel pipe, seamless steel pipe pipeline steel material: GR.B, X42, X46, 52, X56, X60, X65, X70.
