API Std 650 self-anchored storage tanks reinforcement of weld

API 650 stipulates that an open tank should be provided with a wind-resistant ring to ensure that the API Std 650 self-anchored storage tanks 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.

The insert plate weld shall not cross any shell seams and shall be at least the greater of 10 times the shell thickness or 12 in. from any other weld in the API Std 650 self-anchored storage tanks shell including shell seams, shell-to-bottom weld or attachment welds. The butt weld around the periphery of the plate shall be examined over 100% of its length by both liquid penetrant method and radiographic method. The liquid penetrant examination is required on the root pass, on the back-gouged surface, and on the inside and outside finished weld surfaces. Additionally, the weld shall be vacuum box leak tested.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
