API standard 650 petroleum storage tanks check valve
storage tanks API standard 650 petroleum storage tanks designed in accordance with the rules and guidelines of API 650 are called API 650 storage tanks. API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.
To scientifically evaluate the remaining service life of the API standard 650 petroleum storage tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API standard 650 petroleum storage tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API standard 650 petroleum storage tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of API standard 650 petroleum storage tanks plates, openings and fittings exposed during fabrication shall be inspected carefully to make sure that any defects have been uncovered, as well as to determine that the work has been performed properly.Minor defects found may be repaired only after the inspector approves the method and extent of repairs. Materials that have more than minor defects that cannot be satisfactorily repaired shall be rejected.Spot 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.
