Single-deck pontoon floating roof API standard 650 unanchored liquid-storage tanks
API 650 storage tank stipulates that if the thickness of the lower wall panel obtained by calculating the anti-overturning moment is greater than the thickness of the API standard 650 unanchored liquid-storage tanks hydrostatic pressure test (both do not include the corrosion allowance).
Proof Tests for Establishing Allowable Working PressuresBecause pressures in liquid storage tanks built according to these rules vary quite markedly from the tops to the bottoms of the tanks, proof testing of these tanks presents problems not usually encountered in the construction of unfired pressure vessels–especially where the API standard 650 unanchored liquid-storage tanks parts under investigation are located near the bottoms of the tanks. The principal difficulty is devising a test or series of tests that will reliably establish the working pressure that can be permitted on the part of the unproven design without, at the same time, imposing hazardous conditions on other parts located at higher levels in the tank.
To scientifically evaluate the remaining service life of the API standard 650 unanchored liquid-storage tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API standard 650 unanchored liquid-storage tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API standard 650 unanchored liquid-storage tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
