Abstract: Stability of fluid carrying pipelines and mathematical interpretations of phenomena describing vibrations depending on multifactor parameters are topical and of important practical interest. A research is carried out to describe the quantitative and qualitative aspects of the phenomenon where the rotary inertia and transverse shifts of the pipeline are taken into account. Variation of parameters describing vibrations of the pipeline portion are presented by numerical examples- in the form of tables and graphs. Comparisons of the results are drawn.

Keywords: pipeline, vibrations, natural frequency, rotary inertia.
