refrigerated tanks secondary components are those whose failure would not result in leakage of the liquid being stored. Secondary components also include those API standard 650 aboveground steel oil storage tanks components that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature vapors and have a combined tensile and primary bending stress under design conditions that does not exceed 6000 lbf/in.2. Secondary components that could be designed within this reduced stress are roof plates, including roof manways and nozzles with their reinforcement, roof-supporting structural members, and shell stiffeners.
Before pressure test, the main drain hose system of API 650 petroleum storage tank floating roof should be thoroughly flushed.
