Abstract
A mathematical model of internal elastic wave propagation in a bent pipe is developed. For slightly bent pipes, a method is devised for reducing the equations to a lower dimension problem. It is shown that the wave dynamics are described by the Korteweg-de Vries and Klein-Gordon-Fock equations. Thus, the class of problems to which these equations apply is expanded.
