Why Perform a Hydrostatic Test on a Storage Tank? - Elite

API-650,the standard to which many new oilfield storage tanks are constructed and API-653,the standard for tank repair have different requirements for hydrostatic testing.The proximity of the equipment to a water source,the client and the nature of certain repairs can also have an effect on the necessity of a hydrostatic test.Use of Annular Bottom Plate - AST Aboveground Storage Tank Oct 31,2007 unanchored tanks constructed according to API Std 650#0183;See section 3.5 of API 650.When the bottom shell course uses the allowable stress for materials in group 4 and above,an annular ring is required.Typically,these material groups are used in lower MDMT areas of the country,or for large tanks where the higher allowables will reduce the weight of the tank and as a result,the cost.Typical API 650 Tank Sizes - International Tank ServiceBelow are typical API 650 tank sizes and specifications to help our customers determine their exact needs.Skip to content 1085 South Metcalf Street - Lima,Ohio 45804 Phone (419)223-8251
