API standard 650 carbon steel tank inquiry references

When encountering heavy rain or continuous heavy rainfall, the safe operation of API standard 650 carbon steel tank will be affected. For example: the API standard 650 carbon steel tank 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 standard 650 carbon steel tank 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 standard 650 carbon steel tank 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.

API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API standard 650 carbon steel tank floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.
