API 650 aboveground oil storage tanks upper shell

The interior of API 650 storage tanks to be internally lined or coated must have all edges rounded to a minimum of 3 mm radius. Internal welds must be completely seal welded, ground smooth, and free from API 650 aboveground oil storage tanks surface porosity, pockets, and high spots. Remove weld spatter. Vendor as specified on API 650 storage tanks drawing must perform additional surface preparation.

How to effectively increase the service life of API 650 aboveground oil storage tanks oil tanks? It is necessary to check and inspect the oil tank regularly in the process of use, and do a good job in the maintenance and cleaning of the oil tank. The oil tank should be inspected every 6 years. With the increase of service life, the inspection interval should be shortened. Daily maintenance and cleaning of the API 650 aboveground oil storage tanks can prolong the service life of the oil tank. The maintenance of the API 650 aboveground oil storage tanks mainly includes the anti-corrosion inspection of the oil tank, the maintenance of the accessories, and the cleaning of the sediment in the tank.

The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API 650 aboveground oil storage tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.
