Design and evaluation of process equipment damaged by degradation mechanisms
Cablková, Zuzana ; Naď, Martin (referee) ; Lošák, Pavel (advisor)
This bachelor thesis is aimed at the evaluation of selected degradation mechanisms which occurs in process equipment. The assessment is undoubtedly important in terms of safety and prediction of residual life. This issue is demonstrated by two mechanisms described in this thesis. A phenomenon called creep is the first of these mechanisms and appears in environments with elevated temperature. The theoretical part of the thesis covers the basic principles of the creep mechanism and its effect on the material. A marginal but not negligible problem is the occurrence of this damage in welded joints. Many standards deal with the prediction and assessment of creep. Part of this thesis is the mapping and to some extent a comparison of several selected procedures. The second degradation mechanism is related to the presence of aggressive compounds such as sulfide. This can lead to hydrogen embrittlement, blisters, and many other damages. As with creep, an overview of standards devoted to the design, evaluation, or maintenance of equipment used in this way is created for these mechanisms. The content of the practical part of this thesis is the calculation of the evaluation of such a device by using the procedures of the API 579-1 standard.
