X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as Liquefied gas storage tank manufacturer. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of Liquefied gas storage tank manufacturer etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.

Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of Liquefied gas storage tank manufacturer 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 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 stipulates that an open tank should be provided with a wind-resistant ring to ensure that the Liquefied gas storage tank manufacturer tank body maintains its roundness when subjected to wind. There are no hard and fast rules for vault API 650 storage tanks. It can be determined by comparing the equivalent wall height with the maximum height of the unreinforced tank wall.

In December of 2015, our regular India customer sent us an inquiry for Liquefied gas storage tank manufacturer pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.
