API650
API Standard 650, Welded Tanks for Oil Storage is a standard established by the American Petroleum Institute (API) that sets guidelines and specifications for the design, fabrication, and construction of welded steel storage tanks used in the oil and gas industry.
It provides detailed requirements for the construction and maintenance of aboveground, atmospheric pressure storage tanks, often used to store crude oil, petroleum products, chemicals, and other liquids.
The standard is the common basis for the design and certification of large welded steel tanks used for liquids in the Australian Mining and Minerals Processing sectors.
Some key aspects covered by API 650 include:
Tank Design: The standard outlines design criteria, such as the tank's size, shape, and capacity, as well as materials and welding requirements.
Construction: It specifies the welding procedures, testing methods, and quality control measures to ensure the tanks' integrity and safety.
Inspection and Testing: API 650 includes requirements for inspecting the tanks during fabrication and for conducting tests, such as hydrostatic testing, to verify their strength and integrity.
Foundations: Guidelines for tank foundations, including the type of soil, concrete, and anchorage systems, are also provided.
Corrosion Protection: Recommendations for protecting the tanks from corrosion, both internally and externally, are outlined.
API 650 is widely recognized and followed in the industry to ensure the safe and reliable storage of liquids in steel tanks. Compliance with this standard is often required by regulatory authorities and is essential for maintaining the integrity of storage tanks used in the oil and gas sector.
Trang Imagineering is well experienced with this standard, and is an engineering and consulting service that provides design of new tanks, as well as providing guidance on how to repair or modify existing tanks.
