Acoustic Emission Signal Analysis of Steam Piping Materials under Creep Damage Conditions

Popis výsledku v původním jazyce

The components operating in aggressive environment like corrosive fluids, high temperature and stresses undergo corrosion and corrosion related degradation. One of the significant degradation factors in terms of integrity is erosion-corrosion in piping systems and creep in high pressure pipelines of thermal power plants. Prompt detection and assessment of high-temperature deformation and damage process before failure takes place is most important. Non-destructive testing plays a very important role in providing detection of the early signs of corrosion so that corrective action can be taken before damage becomes severe. This article is focused on analysis of a set of steam piping specimens with different degrees of degradation and dissimilar welded joints coming from creep tests. Material degradation was characterized by acoustic emission (AE) method using their source locations and extracted AE parameters. This method is a widely used non-destructive evaluation technique mainly during periodic testin
