Corrosion Fatigue Cracking and Failure Risk Assessment of Pipelines

  • Ihor Dmytrakh
Part of the NATO Science for Peace and Security Series book series (NAPSC)

Problem of corrosion and corrosion fatigue damaging of feeding pipelines of heat-and-power generating units under long-term operating conditions is considered. The two main factors were taken into account: degradation of metals properties and purity of operating aqueous environment that causes by ecological pollution of natural water scoop. Corrosion fracture mechanics approach for assessment of workability and fracture risk of pipelines with cracklike defects is proposed, which is based on conception of threshold and critical cracks depth and also corrosion fatigue crack growth parameters.
