frangible roof tank as per api 650 - API (American

If the unanchored tank qualifies as a frangible roof,then the anchored tank of identical construction ought to,regardless of the anchor design.At the worst,you'd pop all the anchor bolts off,but if you're blowing the roof off in a fire,that's probably not a big concern.anchor floating roof oil tank - plombier-montfermeil.frUnanchored tanks can easily be moved by ood waters and high winds and present serious problems for Storage tanks basic training (rev 2) - LinkedIn SlideShareJul 12,2012 The roof-to-shell joint may be considered frangible and in the event of excessive internal pressure may fail before failure occurs in the tank shell joints or the shell-to Welding after Hydrotest - AST Aboveground Storage Tank Nov 05,2007 unanchored liquid storage tanks roof deck reinforcing plates#0183;1.If water is available for testing the shell,the tank shall be filled with water as follows (1) to the maximum design liquid level,H; (2) for a tank with a tight roof,to 50 mm (2 in.) above the weld connecting the roof plate or compression bar to the
