Based on the assumption of the initial deformed shape of the pipeline without initial stresses, the critical compression force is determined. The pipeline was under the influence of internal and external pressures, compressive forces. A fluid with a given density flowed through the pipeline. The axisymmetric expansion of the pipe and its longitudinal shortening, changes in the temperature of the pipe wall, and the formation of an ejection arch were taken into account. The static interaction of instabilities under the influence of the above factors is studied.
