API 650 open-top tanks inlet diffuser

Static storage loss is also known as "small breathing" consumption. The rise and fall of the temperature in the API 650 open-top tanks leads to the increase and decrease of the pressure in the tank, which makes the mixed oil gas discharged from the tank, and the external air is sucked into the tank, resulting in the oil consumption. Fluid level loss is also called "big breathing" loss. It is the oil consumption caused by the change of gas space volume in the API 650 open-top tanks during the oil receiving and sending operation, which causes the mixed oil gas to be discharged out of the tank, and the external air is sucked into the tank, resulting in the oil consumption due to the change of liquid level height.Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API 650 open-top 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.These API 650 documents will define the bases of design, operation, inspection, tests, examinations, and maintenance of an API 650 open-top tanks industrial facility. Bidders will study and analyze all this API 650 documentation, both during the preparation of the quotation and during the execution of each project activity.The company focuses on quality building, continuously create greatest value for customers, and has achieved good economic and social benefits.
