API Std 650 mechanically-anchored flat-bottom tanks overturning stability

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API Std 650 mechanically-anchored flat-bottom tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

API 650 petroleum storage tank specifications and standards are documents verified by the customer (owner) under different operating conditions; however, API Std 650 mechanically-anchored flat-bottom tanks it must be verified whether these API 650 petroleum storage tank documents are suitable for use and whether they comply with applicable design specifications and/or specifications.

High temperature heat transfer oil fin tube heating device for large API Std 650 mechanically-anchored flat-bottom 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.
