This work deals with the uniform surface mechanochemical corrosion of an elastic thick-walled long cylindrical tube subjected to internal and externa! pressure of environments at different temperatures. The rate of uniform corrosion is supposed to be linear with the stress and inversely as the exponent of time. The problem is then reduced to the first-order ordinary differential equation in a tube cross-sectional size. Analytical solutions of this equation are found. To determine the tube lifetime and the cause of its failure, the method based on various estimating functions is proposed. The algorithm for environmental contamination by corroded material is developed.
