Condition monitoring of cylinders between their examinations

Abstract

In different industrial branches, thin-walled metallic vessels - cylinders are widely used to store fluids and gas. The carried out analysis showed that there is an insufficient number of cylinder technical state diagnostics and control procedures during cylinder exploitation between two examinations or there are no procedures at all. This induced us to examine a current situation of a cylinder technical diagnostics and control and try to suggest new possibilities for its improvement. There we separated two aspects of the condition monitoring problem of cylinders: a current express analysis and suitability evaluation of the technical state of the cylinder between their examinations; forecasting and evaluation of the residual resource suitability of the technical state of the cylinder between their examinations. In the first case, we found a suitable non-destructive control method, in the second, we suggested methodics, it is possible to forecast the residual resource of the exploited cylinder between two examinations. Some results of monitoring possibilities of JSC "Achema" (Lithuania) carbonic acid cylinders are presented.
