The paper deals with linearized partial differential equation for analysis of the transverse oscillations of a pipeline section under an action of pulse fluid flow. Assuming the mathematical model of fluid-caused longitudinal force in cosine form with the Brownian phase and applying the stochastic modification of the second Lyapunov method we analyze a phase variance affect the pipeline section stability.
