In the paper, an evolutionary equation for describing disturbances of a radius of viscoelastic tube with oscillators in the course of flow of visco-elastic liquid is obtained Description of propagation of disturbance pulses in new scales related with sound wave - front, allows to get a higer order nonlinear equation with nonlinearity available in Burgers-Korteweg de Vries equations and with quadratic pressure loss. Numerical solutions of the obtained third, fourth and sixth order equations are also discussed.
