ASTM A671 pipe API Std 650 mechanically-anchored flat-bottom tanks
API 650 petroleum storage tank specifications and standards are documents verified by the customer (owner) under different operating conditions; however, API Std 650 mechanically-anchored flat-bottom tanks it must be verified whether these API 650 petroleum storage tank documents are suitable for use and whether they comply with applicable design specifications and/or specifications.
The main advantages of the external floating roof API Std 650 mechanically-anchored flat-bottom tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API Std 650 mechanically-anchored flat-bottom tanks, the production of external floating roof API Std 650 mechanically-anchored flat-bottom tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API Std 650 mechanically-anchored flat-bottom tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.
Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of API Std 650 mechanically-anchored 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.
The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, API Std 650 mechanically-anchored flat-bottom tanks and steel structures. At the same time, it also adheres to international standards and adheres to the international line.
Steel transportation because of the special material of API Std 650 mechanically-anchored flat-bottom tanks steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
