aluminum sheet 3003 API Std 650 carbon steel tank
Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API Std 650 carbon steel tank 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.
API 650 is the standard for welded tanks for oil storage. It specifies the API Std 650 carbon steel tank design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.
BBN had provided API Std 650 carbon steel tank Hardox plates for more than 15 years for widely applied in coal mining machinery, cement equipment, road construction machinery, engineering machinery, dump trucks, metallurgical area and port fields. In 2016,we brought our customer to visit our API Std 650 carbon steel tank NM400 steel plate producing line and our Shanghai warehouse for 30000 tons plate and structure. As a result, Our client purchased 500 tons NM 400 as first order, which is shipped by 3 times. In future, BBN will always guarantee that all the delivery condition for Hardox plate provided will be with quenching and tempering, which is the best delivery type according GBT 24186 standard.
}The normal operation of API Std 650 carbon steel tank includes receiving oil, storing oil, sending oil and measuring oil. The correct use and operation of oil storage tank is directly related to the production safety and oil loss of oil tank. In order to use and operate the API Std 650 carbon steel tank correctly, it is necessary to be familiar with and master the structure and performance of the API Std 650 carbon steel tank and its accessories, such as the maximum storage capacity of the oil tank, the pressure range that can bear and the safety fabrication specification.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, API Std 650 carbon steel tank sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
