API Std 650 stainless and carbon steel tank recommendation
API 650 internal floating roof oil tank executive standard: domestic design standard: GB50341-2003 "Vertical cylindrical steel welded oil tank design code"; domestic construction standard: GB50128-2005 "vertical cylindrical steel welded oil tank" Construction and Acceptance Specification; API Std 650 stainless and carbon steel tank Foreign design standard: API650-2007 "Standard for Welded Steel Petroleum storage tanks."
Stamping of API 620 Storage Tank PlatesBefore plates required to be stamped by the steel mill are used, the inspector shall see that they bear the stamp. In laying out and cutting the API Std 650 stainless and carbon steel tank plates, at least one set of the original material identification markings should, if possible, be left where it will be plainly visible when the tank is completed. Should the identifying marks be obliterateSpot 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.
No matter what type of storage tank needs to be built, the natural conditions of the geographical area where the tank is located should be fully considered in the design. Because natural conditions will affect the service life, storage safety and construction cost of storage tanks such as API Std 650 stainless and carbon steel tank. Generally, the natural conditions that need to be considered before API Std 650 stainless and carbon steel tank design and construction are: regional temperature, wind load, snow load, ground endurance, external environment corrosion, etc.
