API 650 aboveground oil storage tanks loads
The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API 650 aboveground oil storage tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.
Stamping of API 620 Storage Tank PlatesBefore plates required to be stamped by the steel mill are used, the inspector shall see that they bear the stamp. In laying out and cutting the API 650 aboveground oil storage tanks plates, at least one set of the original material identification markings should, if possible, be left where it will be plainly visible when the tank is completed. Should the identifying marks be obliterateSpot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.
The main reason of "small breathing" loss of API 650 aboveground oil storage tanks is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API 650 aboveground oil storage tanks also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API 650 aboveground oil storage tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
