The seal has metal flexible sections, which can\nbe laterally bent, extending from the roof edge to the\ntank wall, with an elastomeric tip on the sections. Gaskets\ncan fill in gaps or space between the sections to prevent\nescape of vapor.- 20 -PETERS, STEVEN WAYNE...
Device for sealing the floating roof of an oil tank A floating roof-type oil-tank sealing device wherein an inclined connector extends between an upper portion of a seal shoe and the lower portion of outer rim of a floating pontoon, and in such a state that each end of the inclined conn...

In addition, the tank surface roughness reduced the compression of the rim seal on the tank wall, and the effect of scraping decreased. The API withdrawal loss formula for a floating roof tank was recommended to take into account the effect of the rim seal to improve the accuracy of the ...
A rim seal system between the outer periphery of an internal floating roof and the bulk liquid tank wall including a laterally deployed first resilient or flexible seal member and a second laterally deployed rigid seal member interposed between the distal end of the first seal member and the ...
