Issues with internal floating roofs in diesel and gasoline storage tanks
Thread Content
My project involves several tanks, diesel and gasoline storage tanks with a capacity of less than 500 m3. Based on past experience, internal floating roofs are not necessary, but everything should be based on some criteria. Does anyone know if there are any relevant standards specifying the minimum size of tanks for which internal floating roofs are required? Or there are compelling reasons
Our older diesel tanks use fixed-roof designs, while the newer ones have internal floating roofs; all of them have a capacity of over 5000. As for smaller tanks, there are no specific regulatory requirements available. The design codes for oil depots only specify the total capacity, and for Class C liquids, they require the use of flame arrestors, but they do not clearly state which tanks must be designed with internal floating roofs. You can consult the designers to find out what standards they are following.
