What is a Chime? - Definition from Corrosionpedia

A chime,as it pertains to bulk storage tanks,is an annular,flat metal plate welded to the base of the tank.It serves as the interface between the tank's sidewalls and the tank's foundation.The annular chime structure helps to stabilize the tank by transferring radial forces (typically due to hydrostatic pressure and temperature) from the Use of Annular Bottom Plate - AST ForumOct 31,2007 SUG II tanks annular plates#0183;Look a little harder.Somewhere in there is a requirement that annular plates be used for tanks with a certain diameter/ stress level.This should be in the section dealing with bottom and shell design- don't have the standard in front of me,so I can't quote a section number.Tank design - wordFeb 04,2016 SUG II tanks annular plates#0183;For our tank Min Thickness of bottom plates = 6 + 1.5(C.A) = 7.5 mm Nominal thickness = 8 mm NOTE he ordered 10 mm thickness 4.5.2.2 ANNULAR BOTTOM PLATES Annular rings are usually used on larger tanks.An Annular Ring is a thicker plate
