Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.

Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of Liquid ammonia storage tank manufacturers 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.

Inspection of Liquid ammonia storage tank manufacturers bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of Liquid ammonia storage tank manufacturers bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the Liquid ammonia storage tank manufacturers, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of Liquid ammonia storage tank manufacturers bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.
