  • Sampling of heat exchangers tubes in nuclear power plants [Elektronski vir] : induction heating approach
    Sabotin, Izidor ...
    Smooth operation of power plants is associated with periodic overhauls and maintenance. Inspection of the tubes of heat exchangers and selecting appropriate tubes for sampling is one of the most ... important operation of maintenance. This work is focused on applying induction heating technology for the purpose of tube sampling. The first part of the paper covers basic theoretical background on induction heating. In the second part the investigation is divided into two parts. Firstly, the application of induction heating for tube separation is experimentally tested. A significant reduction of breakage force is needed when the tube is locally heated over 500°C. Secondly, the application of induction heating for detachment of a tube from supporting wall is studied. The results show, that induction heating technology is appropriate for both case studies and presents a relevant alternative to conventionally used technologies.
