ISO 630 Gr E355 plates API standard 650 self-anchored tanks

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

Welders participating in the construction of API standard 650 self-anchored tanks must pass the examination and perform welding within the validity period of the qualified items. Special operators such as on-site maintenance electricians, cranes, and shelf workers must hold job certificates. All oil pipelines need to use arc welding for bottoming and electric welding to ensure the welding quality. Oil tanks and process pipelines must be tested for non-destructive flaws in accordance with the flaw detection ratios and methods required by the design and acceptance specifications. The flaw detectors must be certified.

Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API standard 650 self-anchored tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.
