Damages That Occur at Vital Components of the Thermal Power Plant System Detected by NDT Testing

Abstract

Continuous exploitation in very harsh environmental conditions can lead to relatively frequent damages of steam line system. High place among the causes of these damages takes inadequate exploitation and maintenance. This paper describes damages and failures of steam line and provides an overview of NDT testing in order to determine the cause of steam lines failure in thermal power plants. This method may be applied to similar structures and its application in preventive maintenance would help extend the life of steam pipes. The results presented in this paper and conducted research projects allow us to analyze the behavior of supporting elements of steam line in order to determine changes in mechanical properties of materials.
