Date: 20 October


Time: 3PM London/10AM New York

Condition Assessment of High Temperature Applications in Power Generation and Process Technology

Reliability of assets is essential for economic operation in power generation and other process technologies. In order to plan accordingly and to initiate appropriate measures, the information derived from condition based maintenance is vital. The increasing demands regarding flexibility require power plants more and more to be operated at variable conditions.

Other process industries are also facing more flexible market demands. This exposes systems and components to load scenarios under high pressure and temperatures or a combination of both that might not have been considered during design phases. In many cases the design therefore entails great conservatisms. However, the exact remaining design margin of the individual component after being in service for some time is often not known.

In the last 30 years, the AREVA Fatigue Concept (AFC) has been applied successfully as a graded approach to manage fatigue based on the operational load history. The methodology entails an automatic life time evaluation based on real loads that actually occurred. Its creep-fatigue module meets the needs of conventional power plant and process industries in particular. Such lifetime evaluation provides the operator with information allowing a customized maintenance strategy and helps avoiding unplanned down times.

The webinar will highlight and illustrate the possibilities of the integrated creep-fatigue concept that combines design review, design code based creep-fatigue analysis, advanced numerical models, in-situ materials analysis and destructive testing into a hands-on condition assessment.
