The importance of coating maintenance for floating roofs

Anton Martinez and Adam Beers from KTA-Tator cover corrosion and remedies Popularised in the 1950s, floating roof tanks have become increasingly prevalent over the years. These tanks play an important role in the liquid storage industry, most notably oil storage. At refineries, millions of barrels of oil products are stored in tanks that use a floating roof. These tanks are defined by the roof that floats on the liquid and is sealed around the edge. An internal floating roof tank has both a floating roof and a fixed roof. The fixed roof protects the internal floating roof from the atmosphere. External floating roof tanks have a floating roof that is exposed to the elements. The protection from the elements that the fixed roof provides for the internal floating roof can help to prevent failures in extreme weather events, such as hurricanes. Floating roof tanks have several benefits that primarily revolve around their ability to limit the vapour space in the tank. As the liquid in the tank rises and lowers, the floating roof moves in tandem – leaving a minimal amount of space between the liquid and roof called the vapour space, which directly reduces the amount of vapour that...
