API Std 650 carbon steel tank lateral loads on columns

The design metal temperature of API Std 650 carbon steel tank each component exposed to the liquid or vapor being stored shall be the lower of the following:
a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.
b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.

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 carbon steel tank External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.

The heat transfer oil fin tube heating device for large API Std 650 carbon steel tank heats the circulating heat transfer oil in the shell and tube heat exchanger through high temperature and high pressure steam. The heat transfer oil exchanges heat with the medium to be heated in the storage tank through the heating coil, so as to heat the storage medium. High temperature heat transfer oil fin tube heating device has the following advantages:
1. High heat transfer efficiency
2. Reduce heating coil leakage
3. Easy to repair and maintain
