Dec 10,2009·Floating Roof Fixed Roof Tanks - Cost.Wednesday,December 9,2009 By N.Ravichandran  I would like to know purely from construction cost point of view,whether floating roof or fixed roof tank for the same hydrocarbon,capacity will be economical? I would guess that fixed roof should be cheaper,but we have had bids with no significant Floating Roof Tank Seal Internal External Floating Floating roof tank can be divided into two types,internal floating roof and external floating roof.An internal floating roof tank is a floating roof tank fixed an extra fixed roof on the floating roof,to prevent floating roof from wind and rain,and guarantee the quality of the stored oil.Floating Roof Tanks - an overview ScienceDirect TopicsFixed roof this is a low-pressure tank with a roof welded to the shell,regardless of roof design or support methods.Double wall storage tank is a tank with an inner wall to contain a liquid (as used in LNG storage tanks),it has an annulus space filled with insulation and an outer wall.Double wall storage tank.
