Abstract:
A seal arrangement for a floating roof in a storage tank, wherein the roof is spaced at its outer periphery from the inner surface of the tank, thus defining a rim space, includes support members secured at one edge to the roof and extending angularly outwardly into close proximity with the tank wall, and yieldable material carried by the support members in a position to engage the tank wall and effect a seal between the roof and tank wall, said yieldable material having a predetermined shape, whereby engagement thereof with the tank wall covers a predetermined, varying area upon variations in the rim space to thus maintain acceptable contact pressure with the tank at different rim spaces between the roof and tank wall, while at the same time maintaining an effective seal.
