5456 aluminum pipe API standard 650 welded aluminum storage tanks

The working pressure of the low-pressure storage tank is greater than that of the atmospheric storage tank, but its pressure is less than 0.1MPa. API 650 petroleum storage tanks are classified according to their environment: Above-ground storage tank: refers to the bottom of the storage tank at the design elevation of API standard 650 welded aluminum storage tanks and above; the bottom of the tank is below the design elevation of +0.00 but not exceeding.

The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API standard 650 welded aluminum storage tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.

The main content of the inspection of the safety management of metal atmospheric API standard 650 welded aluminum storage tanks is whether the filed data of the storage tanks are complete; whether the operators have received safety management training; whether the problems detected in the past have been resolved. The main inspection content of the tank body of the metal atmospheric pressure storage tank is whether the tank top, tank wall, and bottom plate of the storage tank are deformed, dented, seepage and perforation, etc.; whether the API standard 650 welded aluminum storage tanks accessories are complete and whether there are any abnormalities; No sinking, tilting, etc.
