API 650 aboveground steel oil storage tanks full-fillet weld
Before pressure test, the main drain hose system of API 650 petroleum storage tank floating roof should be thoroughly flushed. Provide blind flanges, gaskets and bolts required for the API 650 aboveground steel oil storage tanks test (other types of covers are also required if necessary). Covers for maintenance shall be provided in accordance with the interfaces specified by API 650 petroleum storage tanks, and these seals shall remain in place after the test; and for those interfaces that are not provided for maintenance covers, the covers can be removed after the API 650 aboveground steel oil storage tanks test.
To scientifically evaluate the remaining service life of the API 650 aboveground steel oil 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 650 aboveground steel oil storage tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API 650 aboveground steel oil storage tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
