As a result, the physical and mechanical preconditions for modelling of deformation microlocalization and pipeline metal fractures after a long operating time were represented. The kinetics of metal fatigue failure of the new pipeline and after a long operating time was determined and behavior of fatigue crack propagation for the entire range of lengths was described: stages of short crack propagation, stable and unstable growth, as well as its braking to a stop.
