Abstract RU 2136564 C1

FIELD: oil industry. SUBSTANCE: proposed device is designed for reduction of losses of oil light fractions at storing oil and oil products in cylindrical tanks and can be used on floating covers of vertical cylindrical tanks for sealing clearance between tank wall and floating cover. Peripheral seal of floating cover has leaf spring pressing oil-and-gasoline resistant cloth wrapped around hose to tank wall. Hose is made of material with sliding friction coefficient at sliding along cloth lower than sliding friction coefficient of cloth sliding along tank wall. EFFECT: increased wear resistance and decreased material usage in peripheral seal. 3 dwg
