Improve the assessment of technical condition of cylinders, allowing for re-examination to establish a guaranteed margin. Test methods and equipment. Research includes theoretical and experimental parts. The theoretical part includes the design and rationale for the approach to the assessment of the technical condition of cylinders during their operation via an integral index - ratio of the residual extension shall be determined by periodic surveys and allows you to set a guaranteed margin of safety based on the remaining life of the bulb. Besides the requirements to materials without brittle fracture cylinders at their destruction. The last concerns the production of new bottles. The experimental part of the research includes experimental verification of theoretical assumptions concerning the use as a criterion for assessing the technical condition - the coefficient of expansion of the residual container, as well as obtaining the experimental curve - the safety factor of the cylinder defined in the re-examination, the coefficient of expansion of the residual cylinder. The presence of such a relationship to the necessary safety margin of strength, or, if the actual margin of safety below the required level - display tank out of service. Experimental studies performed in a certified laboratory using attorneys devices. The novelty of these results is that the first implementation approach to the re-examination of cylinders, allowing you to install a guaranteed reserve of strength under loading test pressure and a criterion for objective decision on the removal of cylinders from service. The experimental setup, which allows to implement this approach.
