70ft diameter API Std 650 flat-bottom oil storage tanks

The most popular standards for API Std 650 flat-bottom oil storage tanks are API Std 650, JIS B8501, BS2654, GB50341, etc. The formulas used in each standard are derived from the hoop stress calculation formula of membrane theory. Combined with the stress characteristics of API Std 650 flat-bottom oil storage tanks, plus the allowable stress, weld coefficient and additional wall thickness, the wall thickness calculation formula is complete. The allowable stress and weld coefficient are determined according to the material performance characteristics and construction technology level of each country. According to different API Std 650 flat-bottom oil storage tanks standards, the calculation results of tank wall thickness are sometimes quite different.The increased uplift described in API Standard 620 tank Appendix Q is intended to apply to the size of the ringwall and foundation but not the anchorage. For tanks with an internal design pressure of 1 lbf/in.2 gauge and over, the uplift, if any, shall be calculated under the combined conditions of 1.25 times the internal design condition plus the design wind load on the API Std 650 flat-bottom oil storage tanks shell and roof.API standard 650 is typically used for carbon, stainless steel and aluminium API Std 650 flat-bottom oil storage tanks tanks located in terminals, refineries, pipelines and other process facilities. Both have different pressure and temperature parameters as well.
