Foundation loading data of API Std 650 austenitic stainless steel storage tanks
Allowable Design StressesThe maximum allowable design stresses for the API Std 650 austenitic stainless steel storage tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.
Determination of API 650 oil tank container: The total volume should be determined according to factors such as transportation mode and API Std 650 austenitic stainless steel storage tanks fuel supply cycle. For train and ship transportation, the maximum consumption is not less than 20-30 days; the maximum consumption for automobile transportation is not less than 5-10 days.
Oil tank is an important equipment for oil storage. The common API Std 650 austenitic stainless steel storage tanks is composed of foundation, bottom plate, wall plate, top plate and accessories. The types of oil tank are various, which can be divided according to the characteristics of material, installation position, storage oil, use, appearance, structure and volume of oil tank. The commonly used materials of metal oil tank are stainless steel, carbon steel, alloy steel, etc.
