Abstract
Analysis of the state of arts of estimation the pipelines operation capacity in Ukraine and other countries taking advantage of the technology of pipeline pigging and integrity management (PPIM аnd ILI technology) has been carried out. Basing on the results of semimodel testing, some aspects of estimation of defects of pipe metal are considered. The load-bearing capacity of a segment of a pipeline with elastic-plastic deformation, which had been detected during the inside-pipeline diagnostics of a long-time operating gas pipeline of the outer diameter 1220 mm has been experimentally investigated. The paper presents some particularities of experimental estimation of the pipeline segment strength in zones of local plastic deformation. The stress-strain state of locally plastically deformed segments of the pipeline has been determined using the semimodel testing. Basing on the investigations, recommendations for engineering practice are proposed.
