Inspecting Low-Pressure Storage Tanks

Low-pressure storage tanks are designed and constructed in accordance with AmericanPetroleum Institute (API) Standard 620 (Ref.1).This standard covers large,field-assembled storage tanks that contain petrole-um gases or vapors as well as other liquid prod-ucts.These large,low-pressure,above-ground tanks are welded from carbon steel.They areFoundations of aboveground steel tanksThe badly designed or badly executed foundations can cause failure condition of the tank and at least it can lead to differential settlement.Welded spatial constructions with thin walls are flexible and they are very sensitive to the settlement.1.Shape of the bottom a) cone up bottom This isDesign of Steel Tanks - The ConstructorA rectangular steel tank is shown in Fig.The rectangular steel tanks are made of steel plates with flat bottom.The widths of steel plates generally adopted are 1.20 m,1.25 m and 1.30 m depending upon availability of the plates.the thickness of steel plates should not be less than 6 mm.
