API 650 open-top tanks internal floating roof loads

The cleanliness of the API 650 open-top tanks has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API 650 open-top tanks clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API 650 open-top tanks is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.

API Standard 620 tank Appendix C describes the factors involved in obtaining adequate foundations for tanks that operate at atmospheric temperature. The foundations for refrigerated tanks are complicated because of the thermal movement of the tank, the insulation required for the bottom, the effects of foundation freezing and possible frost heaving, and the anchorage required to resist uplift. The services of a qualified foundation engineer are essential. Experience with tanks in the area may provide sufficient data, but normally a thorough investigation, including soil tests, would be required for proper design of the foundation.

API 650 tanks in which liquid fluids are stored and designed to withstand atmospheric pressure operation, less than 18 kPa, or internal pressures not exceeding the weight of the API 650 open-top tanks roof, with temperatures no higher than 93, 3 C are included in the scope of this design code.
