Annular and Bottom Plate of a Crude Storage Tank

An annular ring is normally used in cases that generate higher stress in the bottom plate,or those cases where the plate near the shell needs to be thicker than the remaining bottom.The normal (but not universal) practice is to use an annular ring only in those cases where it is required by API-650.Aboveground Oil Storage Tank As Per Api 650 - Industrial Apr 23,2010 aboveground oil storage tanks bottom annular plates#0183;Aboveground Oil Storage Tank As Per Api 650 - posted in Industrial Professionals Dear Professional,I just want to know the following.1.I just want to ask some clarification regarding introducing an annular plate to the bottom plate of a Tank.In API 650 Standard except BSEN 14015,i never found any reccommendation regarding introducing an annular plate and to what minimum tankAboveground Oil Storage Tank As Per Api 650 - Industrial Apr 23,2010 aboveground oil storage tanks bottom annular plates#0183;Aboveground Oil Storage Tank As Per Api 650 - posted in Industrial Professionals Dear Professional,I just want to know the following.1.I just want to ask some clarification regarding introducing an annular plate to the bottom plate of a Tank.In API 650 Standard except BSEN 14015,i never found any reccommendation regarding introducing an annular plate and to what minimum tank
