API 650 aboveground welded storage tanks primary roof drains
The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API 650 aboveground welded storage tanks storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.
Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of API 650 aboveground welded storage 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 main advantages of the external floating roof API 650 aboveground welded storage tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API 650 aboveground welded storage tanks, the production of external floating roof API 650 aboveground welded storage tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API 650 aboveground welded storage 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.
Management concept: integrity is the cornerstone, talent is the foundation, and service is the key.Business philosophy: to keep faith, to win by quality, customer first, win-win development.Based on integrity, win customers with good reputation, win competition with excellent product quality, improve service with customer orientation, and pursue the goal of win-win development in cooperation with customers.Sincerely welcome customers to visit and negotiate business.
The company's logistics team adheres to the development concept of “gathering advantages, providing superior services, creating value, and leading the market”, and tightly focuses on the strategic positioning of “developing large-scale steel logistics and building large-scale steel supermarkets”. Facing the whole country and integrating into the world to build an "one center, one network" international circulation system. Through the development of 5-10 years, it is expected to form a modern steel industry with annual operating income exceeding 2.5 billion yuan.
Both parties shall confirm the API 650 aboveground welded storage tanks material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API 650 aboveground welded storage tanks steel plant.
