Abstract

The paper considers the possibilities for the application of the metal magnetic memory (MMM) method for assessment of the stress-strain state (SSS) and non-destructive testing (NDT) of various-purpose gas and oil pipelines, in order to detect the segments where the development processes of fatigue damage are intensively enhanced. Based on the 100 % inspection of metal components using the MMM method, detection of all potential dangerously-affected zones — the stress concentration zones (SCZs), and the removal of these zones during repair, are carried out. Thus, there is a real opportunity to ensure the safe operation and lifetime extension of metal components based on their actual state.
