Abstract

Complex mechanical systems intended for gas transport are formed by complicated technological piping units. Their main components are gas pipelines, compressor stations, connection and distribution nodes, etc. As a part of their operation, monitoring but especially within long-term intensification of their technical competence, it is necessary to solve a variety of complex technical problems. These are mainly related to monitoring and prediction of lifespan of critical system elements, then also to monitoring corrosion damaged pipeline and related repairs and eventually to rectification of older bridges and other temporary or unsatisfactory technical solutions. Important interacting negative factors in the process are gradual degradation of used material, presence of residual stresses, etc. Solving these problems is unthinkable without active application of experimental modeling, relevant experimental methods and corresponding hardware and software. This mainly includes means of modal analysis and analysis of deformation and mechanical stresses. The article also presents relevant conclusions from solving environment of specific technical problems in the conditions of gas piping transport system in the Slovak Republic.
