How Floating Roof Storage Tanks Work - Detection lesotho single plate floating roof oil tank

Apr 07, 2021There are two basic components to a floating roof tank the roof itself and a peripheral seal. The seal is analogous to a tube that goes inside a bicycle tire. It runs against the side of the tank so that, as the product level moves up and down, constant contact with the tank wall is maintained so that the product cant escape past the seal.
