Jan 15,2007 anchored tanks Roof and Bottom Plates#0183;Hi Henry,You can refer to 3.10.2.5 (addendum March 2000) which states roof plates shall be attached to the top angle of the tank with a continuous fillet weld on the top side only You may want to review the tank design if this connection ask forfrangible roof tank as per api 650 - API (American The intent of frangible roof design is for the roof-to-shell joint to fail preferentially to the shell-to-bottom.This you may have already known.However,in order to achieve this,it is necessary to limit the roof-to-shell strength.So,item 5 was added to accomplish this.You are correct that these items are based on an self anchored tank.Welding sequence for API Tank bottom - AST ForumDec 10,2009 anchored tanks Roof and Bottom Plates#0183;Hello,I need help about welding sequence for bottom,and roof decks Plates in a API tank,in order to reduce as much as posible the effects of deformation becase of the heat.the tank has the following dimensions and specifications Diameter 69.190 mm Heigth 17.017 mm.Roof type External Floating,Double Deck Annular Plates Yes.

Use floating-roof tanks for TVPs from 1.5 psia to 11 psia. The bottom outlet nozzle is usually at least 10 inches above the tank bottom,and the tank volume beneath the nozzle is excluded from any calculation of the working capacity.

A tank with a diameter of 7m (23'-0) cannot have a frangible roof per 5.10fegenbush,I've wondered if that isn't a typo in API-650.
