double-deck-type floating roof API 650 liquid-storage tanks
API 650 "welded storage tanks" API 650 liquid-storage tanks is a standard developed and issued by the American Petroleum Institute (API), which specifies the minimum requirements for the design, manufacture, installation and inspection of welded storage tanks.
API 650 liquid-storage tanks, Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API 650 liquid-storage tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API 650 liquid-storage tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API 650 liquid-storage tanks?
The increased uplift described in API Standard 620 tank Appendix Q is intended to apply to the size of the ringwall and foundation but not the anchorage. For tanks with an internal design pressure of 1 lbf/in.2 gauge and over, the uplift, if any, shall be calculated under the combined conditions of 1.25 times the internal design condition plus the design wind load on the API 650 liquid-storage tanks shell and roof.
