Metal Control of Operated and Damaged Situated Parts and Welded Wire Connections

Abstract:

Investigation of the metal of exploited and damaged bends of water and steam-removing pipes by the spectral-acoustic control method and by the method of electron microscopy was carried out in the work. A sample without damages, a specimen with a corrosion-fatigue crack and a sample with a technological sunset type defect were investigated. Graphic dependencies of acoustic characteristics on the time of operating time are constructed. The values of the acoustic characteristics corresponding to the defective state for the metal of the bends of the water and steam-removing pipes have been established.
