Recently, a promising trend in the construction of new or expansion of existing oil and petroleum depots (tank farms) is the use of tanks of the "glass in glass". The presence of the annular protective wall of the tank allows to keep the product in the event of an accident or violation of basic integrity of the inner tank, to reduce the area of the bund, or get rid of it all, to reduce the consequences of boiling oil and release, as thus thrown petroleum will fall mostly into the annular gap. In normal operation, an additional outer shell is not used and it significantly reduces the efficiency of its devices. But there is an additional option to include the protective cover to the work of the main tank on the perception of internal hydrostatic pressure or as an additional element, which increases its resistance. In this case, the inner and outer tanks filled with product and included in the work. The inner tank hydrostatic pressure tests on both sides, resulting in a one-directional balancing forces. The wall of the main tank experiences less hoop stresses, thereby reducing its thickness. The reduction of the wall thickness of the inner tank allow to use the method of rolling of the installation, which is limited to thick sheets rolled up 16-18 mm. The complexity of the installation, the total cost of the construction of the reservoir, construction time is reduced, the quality of the welds of tanks and reliability compared to the sheet-mounting method increased.
