API Std 650 self-anchored tank structural period of vibration
Before pressure testing, thoroughly flush the API 650 tank floating roof primary drain hose system. Supply API Std 650 self-anchored tank blind flanges, gaskets, and bolting (for other types of blanking covers as may be required) necessary for testing.
Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API Std 650 self-anchored tank 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.
When the API Std 650 self-anchored tank is welded, the weldment should be fixed rigidly. After welding, when the weldment is cooled to normal temperature, the rigid fixation can be removed, which can effectively prevent angular deformation and wave deformation. Although some measures have been taken, the welding deformation of API Std 650 self-anchored tank is still unavoidable, so it is necessary to take corrective measures to compensate the deformation. Mechanical correction is to make the parts easy to deform in the welding process by mechanical or other rigid materials to produce simple deformation, so as to restore the state before welding.
