Evaluation of the serviceability and fracture hazard for a feeding pipeline with corrosion defects

We study the problem of corrosion-fatigue damage to the feeding pipelines of power-generating units of thermal power plants in the course of long-term operation. The diagrams proposed for the evaluation of the serviceability and fracture hazard of pipelines with defects are based on the concept of t...

Zusammenfassung:We study the problem of corrosion-fatigue damage to the feeding pipelines of power-generating units of thermal power plants in the course of long-term operation. The diagrams proposed for the evaluation of the serviceability and fracture hazard of pipelines with defects are based on the concept of threshold and critical crack depths and the parameters of growth of corrosion–fatigue defects. The factor of possible presence of technogenic organic impurities in the heat carrier is also taken into account.
