Seismic design for API 650 SUG I tanks

Standard API 650 tank calls for calculations based on the specific gravity of the liquid product being stored. This permits the thickness of the steel API 650 SUG I tanks needed as well as other specifications of how the tank is built to be determined by the weight of the API 650 tank.

Combination of Design Loads
The inner tank API 650 SUG I tanks shall be designed for the most critical combinations of loading that result from internal pressure and liquid head, the static insulation pressure, the insulation pressure as the inner tank expands after an in-service period, and the purging or operating pressure of the space between the inner and outer tank shells, unless the pressure is equalized on both sides of the inner tank.

Deformation of the welding seam of the API 650 SUG I tanks is a common quality problem during the actual use of the API 650 SUG I tanks, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API 650 SUG I tanks is mainly caused by the lack of reserved welding seam gap and irregular operation. The oil storage tank has not reserved the corresponding weld gap, resulting in deeper root removal during the front welding activity. The heat output of the weld will increase under the influence of a long time, and the deformation of the weld will gradually become serious.
