SIMULATION AND ANALYSIS OF THE MECHANICAL BEHAVIOUR OF GAS STORAGE TANKS
Abstract
Pressure tanks are closed containers in which fluids are kept at a pressure higher than
atmospheric pressure or under vacuum at different temperatures. They are used for storing various fluids or gases, transporting them or for various technological purposes. Based on the simulation results, the influence of the container thickness and internal pressure on the distributions of the maximum values of total deformations and equivalent stresses were analyzed. For the range of input parameters analyzed (internal gas pressure and container shell thickness), the construction and design solution that meets the requirements of the design (maximum gas pressure of 19.6 bar, testing pressure (with water) 29.6 bar, internal volume 16850 litres, nominal diameter of 2000 mm and length of 5627 mm) is that with a container having a shell thickness of 16 mm to meet the safety criteria provided in SR EN 13445-3:2014 with subsequent amendments.
