In such tanks the roof to shell joint is intended to fail in the event of overpressurization venting the tank and containing any remaining fluid.

Frangible tank roof design.

F 4 1 establishes the maximum design pressure p for a tank that has been constructed or that has had its design details established. Failure of the roof to shell junction can be expected to occur when the stress in the compression ring area reaches the yield point says f 6 calculated failure pressure. A frangible roof is a roof to shell joint or junction that is weaker than the rest of the tank and will preferentially fail if the tank is over pressurised. In fact the frangible roof design fulfills the venting requirements due to deflagrations inside tanks for most tank sizes greater than about 35 feet in diameter.

In the event of over pressurization the frangible roof to shell joint is designed to fail before the tank shell or the shell to bottom joint. The api 650. The reasoning behind present api design formulas is reviewed. This failure is intended to vent the tank and contain any remaining fluid.

The concept of frangible roof only applies to flat bottom cone roof tanks with limited roof apex angle. A frangible roof joint forming a flexible gastight connection between a tank shell and a roof comprising an annular link mechanism sealingly secured at or adjacent a first edge thereof to a rim of. Api 650 gives rules for the design of frangible roof joints in fluid storage tanks. See figures 7 and 8.

That is of course if the tanks are built according to the rules for frangible roofs.
