Abstract
Considering the conditions to which steels used for the manufacture of steam pipelines
are exposed, the micromechanism of their destruction in exploitation is exclusively the ductile one.
In order to make an estimation of the level of the damage that occurs in exploitation, in this paper a
combined experimental and numerical procedure has been developed based on micromechanical or
local approach to the fracture mechanics of metallic materials. After the analysis of the results
obtained for micromechanical criterion of failure for virgin steel and that used in the steam pipeline,
a proposal for prolongation of the working life of tested steel for steam pipelines until the next
overhaul is given.
