API 620 - Design & Construction of Low-Pressure Storage Tanks

API 620, Design and Construction of Large, Welded, Low-Pressure Storage Tanks, is a standard developed and published by the American Petroleum Institute that gives requirements for the design and construction of large, welded storage tanks with pressures in their gas or vapor spaces of not more than 15 lbf/in.2 gauge. The most recent edition of this standard (12th Ed.) was released October 2013. API 650 ABOVEGROUND STORAGE TANKS, Part I:Code elements of the tank. In view of the materials of construction, requirements and recommendations are set forth, i.e.:erection sequences, welding procedures, tests and inspections as well as guidelines for operation. 1.1.2) API 620 The standard API 620 covers the design and construction of large tanks API 650 Advance Tank & ConstructionAPI 620 governs the design and construction of large, welded, low pressure storage tanks. These storage tanks operate at 250°F or less with an operating pressure of up to 15 PSI. API 620 Tanks are generally utilized for Liquefied Natural Gas (LNG) storage as well as other chemicals which require internal design pressures in excess of those
