API Std 650 cylindrical liquid-storage tank shell nozzle flanges
The welded API 650 tank in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure API Std 650 cylindrical liquid-storage tank is permitted when additional requirements are met.
X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as API Std 650 cylindrical liquid-storage tank. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of API Std 650 cylindrical liquid-storage tank etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.
Uplift on FoundationFor API Standard 620 tanks with an internal design pressure less than 1 lbf/in.2 gauge, the uplift shall be taken as the smaller of the maximum uplift values computed under the following conditions:a)The internal design pressure times 1.5 plus the design wind load on the shell and roof.b)The internal design pressure plus 0.25 lbf/in.2 gauge plus the design wind load on the shell and roof.
