ISO 630 Gr E275D plates API 650 flat-bottom oil storage tanks
Oil tank accessories are an important component of metal oil tanks. Common accessories of API 650 flat-bottom oil storage tanks include manholes, light holes, oil measuring holes, breathing valves, safety valves, and fire extinguishers. The functions of these accessories are different. Some are to ensure the storage quality of various oil products, some are to ensure the normal operation of oil products receiving and dispatching, and some are to ensure the safety management of API 650 flat-bottom oil storage tanks, etc.
The calculated thickness of the above-mentioned wall panels required by the hydrostatic pressure is also It API 650 flat-bottom oil storage tanks should be increased by the same ratio, unless special analysis is performed to determine the seismic overturning moment and the corresponding stress at the bottom of the wall of each layer of API 650 tank. =====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 650 flat-bottom oil storage tanks hydrostatic pressure test (both do not include the corrosion allowance).
