Behavior of API standard 650 petroleum storage tanks
The heat transfer oil fin tube heating device for large API standard 650 petroleum storage tanks 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 efficiency2. Reduce heating coil leakage3. Easy to repair and maintain
Impact Requirements for Controlled-rolled or Thermo-mechanical Control Process (TMCP) Plates: Subject to the approval of the Purchaser, controlled-rolled or TMCP plates (material produced by a mechanical- thermal rolling process designed to enhance the notch toughness) may be used where normalized plates are required. API 620 welded storage tanks each used plate, as rolled, shall be Charpy V-notch tested to the requirements of R.2.1.2.
Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API standard 650 petroleum storage tanks tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.
