Aboveground API standard 650 self-anchored flat-bottom steel tanks

High temperature heat transfer oil fin tube heating device for large API standard 650 self-anchored flat-bottom steel tanks has the advantage of reducing the leakage of heating coils. The heating medium of the large storage tank heating device is high-temperature heat-conducting oil. The boiling point of the heat-conducting oil is high, usually higher than 200°C. At high temperatures, the pressure on the heat-conducting oil circulation pipeline is very small, which greatly reduces the occurrence of heating coil leakage accidents. At the same time, the temperature difference between the inside and outside of the tube is guaranteed.

Uplift on Foundation
For 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.

One of the most widely used design codes is the API 650 Standard, from the American Petroleum Institute. The main objective of this standards API standard 650 self-anchored flat-bottom steel tanks is, through the requirements contained in its various sections, to facilitate the purchase and construction of vertical, aboveground, welded fabricated tanks assuring that required safety regulations are met.
