Api Tank Design Pressure

Api 650 is widely used for tanks that are designed to internal pressures of 2 5 psi or less and store products such as crude oil gasoline chemicals and produced water.

Api tank design pressure. Api 650 is the standard governing welded tanks for oil storage. Welded steel tanks for oil storage. For large tanks which are assembled in field and are used for storage of petroleum intermediates and petroleum products. Excessive losses of volatile liquids particularly those with flash points below 100 f 38 c may result from the use of open vents on fixed.

The principals of this standard can be applied to fluids other than petroleum products. Api 620 regulates the design and manufacture of large steel low pressure storage tanks usually larger than 300 feet in diameter. Design and construction of large welded low pressure storage tanks.

By contrast api standard 650 is typically used for carbon stainless steel and aluminium tanks located in terminals refineries pipelines and other process facilities. Api standard 2000 venting atmospheric and low pressure storage tanks gives practical rules for vent design.
