API Std 650 insulated tanks fittings
For areas with high groundwater levels, the operator should take anchoring and anti-floating measures for buried horizontal API Std 650 insulated tanks oil tanks; API 650 oil tanks can be used for heavy fuel oil, heaters are separately designed, and buried tank material outlets are installed with bottom valves and connections. consider.
Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API Std 650 insulated 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.
Natural ventilation loss: the main cause of natural ventilation loss is that the API Std 650 insulated tanks is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API Std 650 insulated tanks is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.
