Stabilization of Sagging Membrane Coverings of Vertical Low Pressure Cylindrical Tanks
Abstract: The article is devoted to the improvement of the design of coatings for typical vertical cylindrical tanks. It is proposed to use sagging thin-sheet membrane shells instead of traditional dome coatings. This allows to significantly reduce the metal consumption of both the coating and the tank as a whole. The optimal parameters of membrane coatings for typical tanks with volumes of 10, 20, 30, 50 thousand cubic meters, having diameters of 28.5; 39.9; 45.6; 60.7 meters, respectively, are determined. The load for all snow regions of Russia, varying within 0.5...4 kPa, is taken into account. The effect of excess pressure of petroleum vapors on the stress-strain state of structural elements of sagging membrane coatings is considered. A dangerous emergency result of excess pressure can be the so-called «reverse exhaust» of the coating. To prevent this phenomenon and stabilize the membrane coating, it is proposed to use a central post in the form of a pipe or a system of braces. The influence of stabilizing elements on the stress-strain state and technical and economic indicators of membrane coatings of vertical cylindrical tanks is investigated. The boundaries of rational application of the proposed stabilization methods are determined.
Keywords: vertical cylindrical tank, membrane coating, stress-strain state, stabilization, optimal parameters.
