May 22,2008 welded steel oil storage tanks bottom annular plates#0183;According to API 650 sect 5.5 an annular ring is soley dependant on the stress in the bottom course.According to BS 2654 a tank over 12.5m dia must have an annular ring.I would like to know why the annular is necessary? Because butt welded the completely flat and even surface makes the shell to bottom weld much stronger but there must be more.API 650 Advance Tank ConstructionAPI 650 is the standard governing welded tanks for oil storage.It dictates tank design,fabrication,welding,inspection,and erection requirements.API 650 is widely used for tanks that are designed to internal pressures of 2.5 PSI or less and store products such as crude oil(PDF) WIDTH OF ANNULAR BOTTOM PLATESThe peripheral bottom part (annular bottom plates) also takes part in the calculations,as a part of stabilising forces,depending on its thickness,width,strength.
