The article suggests a method for modelling the stress-strain state of layered elastic-creeping tube. This method is based on a combination of the theory of averaging and creep theory. This theory takes into account the previous stress state and its effect on the subsequent deformation period. Creep kernels for the averaged problem are found in the explicit analytical form. These formulas can be used to estimate displacement and stress fields during long-term loading of a composite tube.
