3003 aluminum tube API Std 650 aluminum tanks
API 650 external floating roof storage tanks are generally called external floating roof API Std 650 aluminum tanks tanks, which means that the storage tanks are externally open tanks without a dome design, and are equipped with vertical floating roofs. API 650 external floating roof storage tanks are usually used for large More than 20,000 cubic meters of open steel API Std 650 aluminum tanks storage tanks for storing volatile petroleum products such as crude oil, gasoline, kerosene, etc.
The main content of the inspection of the safety management of metal atmospheric API Std 650 aluminum 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 Std 650 aluminum tanks accessories are complete and whether there are any abnormalities; No sinking, tilting, etc.
Standard Hydrostatic and Pneumatic TestsAfter erection is completed and stress relieving, radiographic examinations, or other similar operations, as may be required, are performed, each tank shall satisfactorily pass a series of hydrostatic and pneumatic tests as prescribed in 7.18.2 through 7.18.6. Whenever a solution film is specified in this section to be applied to welding, linseed oil or another equivalent material for disclosing air leakage may be substituted. In freezing weather, linseed oil or a similarly suitable material shall be used.The attachment welding around all openings and their reinforcements in the walls of the API 620 tank shall be examined by the magnetic-particle method both inside and outside the tank API Std 650 aluminum tanks. When the underside of a tank bottom rests directly on the tank grade (and is not accessible after erection), such examination of welding on the underside of the bottom and subsequent air testing may be omitted.
