Internal floating roof tank consists of a permanently fixed roof with a floating roof inside the tank. The internal roof floats on pontoons or has a double deck for floatation over the liquid surface (Figure 3). These tanks will generally be found in service conditions where high volatility (Low Flash Point) or toxic liquids are stored. In a fixed roof tank without a floating cover, the liquid surface is in direct contact inner cover inner cover Storage tanks, Fixed-roof tanks, Floating roof tanks storage tank inner cover floating roofProducts Characteristics Industry Types Advantages Other uses Construction Future Versions Equipment Function Summary Operation Examples A typical external floating roof tank consists of an open-topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid, rising and falling with the liquid level. The floating roof is comprised of a deck, fittings, and rim seal system. Floating roof decks are constructed of welded steel plates and are of three general types pan, pontoon, and double deck. Horizontal tanks are constructed for both above-ground and underground service.

How Floating Roof Storage Tanks Work. As the name suggests, floating roofs float on top of a product, such as crude oil, in a storage tank . As the level of the product fluctuates, the floating roof moves up and down with it, maintaining a sliding contact with the tank wall. The objectives are to prevent evaporation loss or minimize evaporation storage tank inner cover floating roofinner cover inner cover How Does a Floating Roof Tank Work - GSC TanksThis floating roof adjusts its height by floating up and down depending on the product level. Such industrial storage tanks are widely used to store volatile oil, such as aviation fuel, gasoline, crude oil, diesel oil, and other light oils.
