ABSTRACT
The effect of gas generationunder the gas-liquid flow on the heat transfer and hydraulic characteristics of pipelines presented in this work.The urgency of the task is determined by the importance of the specific heat ratio of the boundary gas layer under the pipeline transportation of the hydrocarbons.The terms of the heat transfer of the transported fluid through the pipe to the environment was determined taking into account the complexityofthe process of heat transfer.
The influence of the gas formation in the pipeline capacity was investigated. Effect of temperature changes at the interface of liquid - pipe on the «Buzovna – Sabunchi» pipeline (SOCAR) was experimentally evaluated.
The necessity to consider heat transfer processes in a thermal instability for flows regulating under the pipeline pumping of gas-liquid systems have been shown.
KEYWORDS: pipeline, thermal conductivity, thermal insulation, gas, vibrations, heat emission, gas release, insulation.

ABSTRACT
The article describes an approach to provide safe operation of gas trunklines linear parts operated under the impact of intense non-project kinematic loads.The prerequisites are given, under which the correct assessment of technical condition of gas trunklines linear parts operated under the impact of such loads is possible. Based on the incident on the connecting pipeline of compressor station “Urgala” the typical mathematical model of accidents on the gas trunklines linear parts operated under the intense non-project kinematic loads is built.
KEYWORDS: gas trunklines linear parts; technical deterioration;non-project kinematic loads; loading cycle; local defects.
