Anotace |
The steel piping systems of power and chemical plants have been operating at high pressure and temperature for decades. They gradually degrade by plastic deformation, accompanied by cracks – creep, and their service life is reduced. Conventional methods of detecting the degree of creep damage require sampling and long-term rupture tests in the laboratory. The aim of the project is to create a non-destructive diagnostic system using the method of acoustic emission (AE) for operational monitoring of the initiation and propagation of creep crack. Continuous monitoring of creep damage formation using AE will also contribute to reducing the risk of a possible accident. The subsequent processing of the obtained data will allow more accurate estimation of the residual life of the pipeline.
