API Std 650 ground supported flat-bottom tanks isolation valves
After the API Std 650 ground supported flat-bottom tanks is manufactured, air tightness test and water filling test are carried out according to the design requirements, and the pipeline must be subjected to pressure test to fully meet the acceptance technical specifications. Improve the quality assurance system, adhere to the principle of who constructed is responsible for the quality of the project, conduct regular quality inspections, and immediately rectify any problems. Fill in the API Std 650 ground supported flat-bottom tanks installation technical records in time to ensure the synchronization, integrity and reliability of the technical data.
Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API Std 650 ground supported flat-bottom 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.
There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API Std 650 ground supported flat-bottom tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API Std 650 ground supported flat-bottom tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.
