In comparison to other tank types,fixed roof tanks don't have a floating roof that adjusts according to changes in the liquid level.Fixed roofs tanks can be made of steel and are fully welded to make them liquid and vapor tight.World Safe International - HomeFixed-roof tanks.Fixed-roof tanks are vertical steel cylinders with a permanently attached roof.In the petroleum and petrochemi- cal industries,these permanent roofs are usually cone shaped and are sometimes referred to as fixed-cone roof tanks.Such roofsWorking Standing Losses Understanding Tank Emissions One of the most vital tank characteristics is the roof type.The most common types are floating-roofsand fixed-roofs.Fixed roofs are permanently affixed to the top of the tank,which creates a great deal more space for vapors to accumulate when the tank is less than full.The less material in the tank,the more room for vapors to build up.
