Frangible roof joint for storage tanks - Monsanto Company

What is claimed is 1.A frangible roof joint for small diameter tanks wherein the joint forms a flexible gastight connection between the tank shell and the roof and comprises annular link means containing an annular plate having an inner edge corresponding to a first edge thereof and an outer edge corresponding to a second edge thereof sealingly secured at or adjacent the first edge to a rim Foundations of aboveground steel tanksWelded spatial constructions with thin walls are flexible and they are very sensitive to the settlement.1.Shape of the bottom a) cone up bottom This is more often used bottom shape.It allows water drains from inside of the tank to the situated near to the shell draw-off sump.Flexible Connections for Chemical Storage Tanks Poly Proper Installation of Pipe Supports.Pipe supports positioned CORRECTLY pipe support must be placed after the flexible connection to allow the tank to properly expand and contract..Pipe supports positioned INCORRECTLY pipe support incorrectly placed before the flexible connection does not allow the tank to properly expand and contract,which can cause the piping or tank to crack over time.
