摘要：Nowadays, there are many types of roofing designed for steel vertical tanks. Their working properties are also quite different. The paper considers technical solutions of tank roofs constructed for storage of liquid aggressive liquids of oil type and the like. It describes a new technology which is being actively introduced at Russian enterprises at the moment. According to this new method, load-bearing structures are installed above roof flashing sheets, thus protecting them from direct contact with an aggressive environment. It ensures corrosion resistance and, consequently, durability of the tank stationary roof. To reduce the risk of corrosion damage it is necessary to increase metal thickness. The researchers suggest using stainless steel instead of regular carbon steel. In this case, steel sheets thickness can also be lessened thus making it possible to reduce loads on underlying constructions. The proposed solution of the units fastening the tank roof elements also simplifies construction inspection activities.
