A573 grade 58 plates API 650 ambient temperature tanks

Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API 650 ambient temperature tanks. The mechanical cleaning of the API 650 ambient temperature tanks can make the inside of the tank be thoroughly cleaned in multiple directions, and the cleaning quality is high, and the cleaned oil does not contain lumpy impurities. While the walls and roof of the API 650 ambient temperature tanks cannot be cleaned in multiple directions during manual cleaning, and the cleaning quality is not easy to be guaranteed. The oily sewage collected after cleaning usually contains a lot of lumpy impurities, and these oil products are difficult to clean.Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of API 650 ambient temperature 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.This standard applies only to API 650 tank API 650 ambient temperature tanks whose entire bottom is uniformly supported and to API 650 tank in non-refrigerated service that have a maximum design temperature of 93°C (200 °F) or less.Enterprise mission: to create value added steel products API 650 ambient temperature tanks and provide first-class serviceWe are committed to quality.
