Evaluation of degradation of heat stressed pipelines

Popis výsledku v původním jazyce

Piping systems of boilers are mainly exposed by high temperatures, pressures and corrosive loads. This corre-sponds to the choice of materials boiler pipeline. These materials are in most cases special stainless steel for ener-getic equipment. Article deals with the evaluation of the resulting degradation of thermally stressed pipe boiler, which occurred after the increase boiler capacity. Degradation showed an increased amount of corrosion products on the inner surface of the pipeline, which resulted in clogging of pipes, formation of cracks and leakage of steam. Complex analysis was carried out of corrosion products and material microstructure pipelines. The result was that occurred to intergranular corrosion of pipelines in loaded state. On the basis of this was carried out analysis of the material in the unloaded state. Chemical composition and microstructure correspond to prescribed standards and requirements. Test of resistance to intergranular corrosion revealed that in the stee
