The technique of calculating the creep and fracture of thick-walled pipeline in a relatively high temperature conditions and exposure to hydrogen is considered. The local nature of the problem is provided by the local effects of temperature on the outer surface of the pipe. The case of linear increase of the local zone temperature with time is examined. The theory of accumulation of damages in Yu. N. Rabotnov’s form is applied to definition of the moment of destruction.
Keywords: local heating, non-uniform temperature field, thick-walled pipeline, chemical interactions parameter, creep, finite element method.
