Quality inspection of API 650 storage tanks

storage tanks API 650 storage tanks designed in accordance with the rules and guidelines of API 650 are called API 650 storage tanks. API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.

To scientifically evaluate the remaining service life of the API 650 storage tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API 650 storage tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API 650 storage tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

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 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.
