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 carbon steel 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 carbon steel storage tanks test.

When encountering heavy rain or continuous heavy rainfall, the safe operation of API 650 carbon steel storage tanks will be affected. For example: the API 650 carbon steel storage tanks is submerged, the oil unloading valve and the flame arrester valve are broken by water and the oil tank leaks. The oil tank area must do emergency work to prevent rainstorm to ensure the safety of the oil tank. Here are some safety protection measures for API 650 carbon steel storage tanks in heavy rain.

Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API 650 carbon steel storage tanks air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.
