API Std 650 uplifting tanks shell-to-bottom fillet welds
Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API Std 650 uplifting 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.
The inner layer of API 650 tank is the same as that of single layer tank. It is made of high-quality steel plate in strict accordance with the standard of "steel welded atmospheric pressure vessel". The thickness of API Std 650 uplifting tanks steel plate reaches the standard and the service life is longer.
In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate API Std 650 uplifting tanks for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 API Std 650 uplifting tanks and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
}Operation points of sand blasting rust removal for metal storage tank, API Std 650 uplifting tanks:1. The equipment should be as close as possible to the workpiece to be processed, so as to reduce the pipeline length and pressure loss, avoid excessive pipeline wear, and facilitate the construction personnel to contact each other.2. The jet pipe should be straight as much as possible to reduce the concentrated wear at the bend. The wear direction of the bend should be changed frequently to prolong the service life of the pipe.3. Strictly control the process parameters.
