Doroshenko Y. Development methods of gas pipeline damages localization for leading repair works

Research object: gas pipelines linear areas with the damages. Research purpose: development methods of penetration defects of а gas pipeline and lengthy defects gas pipeline section localization and research efficiency of their application. Research methods: mathematical design of unstationary gas dynamic processes in a gas pipeline, planning of experiment. Theoretical and practical results: repair gas pipeline without stopping transporting the gas and replacement of the lengthy defects gas pipeline section without emptying and blowing out of gas pipeline. Novelty: first the device motion dynamics in the stream of the transported gas with taking into account influencing of emergency leak of gas is explored in theory, influence of the dynamic loadings is set on device's construction for localization of leak place and retainer while the device is stopped in the emergency leak place is explored, the model device for localization of leak place motion is experimentally explored. The extent of introduction:the developed method of penetration defects of а gas pipeline localization has been introduced at the Pervomaisk Line Department (trunk gas pipeline branch Cherkasytransgaz). The sphere of using: gas-transport system of Ukraine
