FIELD: non-destructive control.
SUBSTANCE: in the method heating of wall of vessel (pipeline) under isolation for creating a temperature drop transversely to isolation layer is performed by method of blowing gas through internal hollow, with appropriate adiabatic gas temperature increase, while blowing is performed up to optimal pressure ρopt, at which adiabatic increase of gas temperature is maximal.
EFFECT: possible heat vision control of non-separable vessels and extensive pipelines, decreased energy costs of control.
