Information × Registration Number 0216U001427, 0113U001099 , R & D reports Title Elaboration of scientific foundations of multiparameter technical state control of long term use steelwork according to real value of physical and mechnical characteristics of their material, as well as type and saze of defects popup.stage_title Head Karpash Oleg Myhailovych, Registration Date 11-02-2016 Organization Ivano-Frankivsk National Technical University of Oil and Gas popup.description2 As a result of the work the grounded theory of influencing factors and the effects of changes in the microstructure of the material of long-term use steel structures in basic industries were developed; the methods for non-destructive determination of the yield stress/strength and toughness taking into account the degree of degradation of materials microstructure of metal constructions in operating conditions, were improved; new non-destruction method of identification the degradation steel microstructure degree was developed; the method for defects classification, identified by non-destruction methods, by types and sizes, was developed. The system for monitoring the concentrations of non-technological fluids in the cavities of gas pipelines was developed and the method of determining the concentrations of the fluids on the pipeline route was proposed. The methodology for the formation of data banks on physical and mechanical properties of structural steels and their degradation during prolonged use; projects of normative documents regulating the scope and procedure for applying the developed technologies on assessment of technical conditions of steel structures? were developed. New methods for calculating the residual resource of metal structures safe operation by the degradation degree of their performance characteristics and the microstructure were suggested.
