API standard 650 aluminum storage tanks repair

Safety comparison between mechanical cleaning and manual cleaning of vertical storage tank, API standard 650 aluminum storage tanks. Closed cleaning is adopted for mechanical cleaning. During the cleaning process, operators are not required to enter the tank. The inert gas space formed in the storage tank can prevent the occurrence of fire, explosion and other accidents.

The foundations for refrigerated tanks are complicated because of the thermal movement of the tank, the insulation required for the bottom, the effects of foundation freezing and possible frost heaving, and the anchorage required to resist uplift. The services of a qualified foundation engineer are essential. Experience with tanks in the area may provide sufficient data, but normally a thorough investigation, including soil tests, would be required for proper design of the foundation.
