API Std 650 ambient temperature tanks seismic use group iii
The temperature requirements of the API 650 oil storage tank area are closely related to the evaporation loss, energy loss, API Std 650 ambient temperature tanks storage and storage platform tank materials and the selection of detection instruments, or the temperature of the API 650 oil storage tank area. The cost of storage has a direct impact.
API Std 650 ambient temperature tanks, Vertical oil storage tank is an important equipment for many enterprises to carry out production, which provides important support and help for the storage of many reagents. Vertical storage tank is generally used as atmospheric pressure vessel. Advantages: the filling rate of cylindrical structure is second to that of spherical tank, and the largest volume of the storage tank can be made into tens of thousands of cubic meters. The structure is simple and the construction requirements are relatively low.
Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t – c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t – c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API Std 650 ambient temperature tanks where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.
