API Std 650 aboveground oil storage tanks shell reinforcing plate

Materials for API Std 650 aboveground oil storage tanks primary components shall comply with the requirements of Tables R-1 and R-2. All primary components shall be impact tested in accordance with R.2.1.2 through R.2.1.4. Impact testing of API 620 welded storage tanks plates, including structural members made of plate, shall comply with Table R-1. Impact test specimens shall be taken transverse to the direction of final plate rolling.

Above-ground API 650 storage tanks (vertical cylindrical flat-bottomed storage tanks) allow the storage of large volumes of goods at low cost. The only limitation is that they API Std 650 aboveground oil storage tanks can be used under atmospheric pressure or relatively small internal pressure. There are different specifications and standards for the design of API 650 storage tanks.

During the use of API Std 650 aboveground oil storage tanks, the tank material is prone to crack and leakage under the action of pressure, corrosion, wear and other conditions. Especially in the oil producing area, the temperature difference in four seasons is large and the natural environment is bad, which will accelerate the consumption of oil storage tank and cause many potential safety hazards. Therefore, the API Std 650 aboveground oil storage tanks must undergo strict inspections before being put into use after the production and installation are completed, so as to avoid cracks and leakage in short-term use and affect production safety.
