CSA G40.21 Gr 350WT plates API 650 ground supported flat-bottom tanks

Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API 650 ground supported 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 API 650 is the American standard for welded flat-bottomed vertical API 650 ground supported flat-bottom tanks storage tanks. This standard dictates tank design, manufacture, welding, inspection and installation requirements.A West Africa customer 112000pcs ASTM A36 Screw Ribbons for project West Africa Gas Pipeline (WAGP) in 2017 year. A36 carbon steel’s strength, formability, and excellent welding properties make it suitable for a large variety of applications, including welding, fabricating, and bending. Our customer is satisfied with our carbon steel A36 Screw Ribbons. If you are interested in our steel machining parts, welcome to contact us.All oil tanks have service life. Due to the pressure of the oil stored on the tank and the corrosion of the oil and external environment on the tank, the oil storage tank will gradually become thin or crack after a long time. Due to the different materials and environment of API 650 ground supported flat-bottom tanks, the consumption of API 650 ground supported flat-bottom tanks is different, so it should be taken into account when evaluating the remaining service life of API 650 ground supported flat-bottom tanks.The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel API 650 ground supported flat-bottom tanks plates.
