API Std 650 stainless and carbon steel tank methods of examining joints

The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API Std 650 stainless and carbon steel tank External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API Std 650 stainless and carbon steel tank under-bottom insulation shall be designed to resist the combined pressures from the product load, the overturning seismic load and the vertical seismic load. These seismic pressures may be combined by SRSS.
The bearing ring under the shell shall be designed to resist the calculated OLE peak compressive force in the tank shell due to overturning (see API 650 oil tank, Section E.6.2.2), including dead and live loads. A 33 % increase in allowable bearing stress is permitted.

Under the condition of static storage without receiving and sending operation, the temperature of gas space, evaporation rate, depth and pressure of vapor in the API Std 650 stainless and carbon steel tank will change with the change of temperature and pressure in a day. The oil loss caused by the process of discharging oil vapor and inhaling air gas is called "small breathing" loss, which is also called static storage loss of oil tanks.
