Abstract

The presented dissertation discusses the issue of sealed flange connections of pressure vessels. The first part of the thesis presents a basic description of the problem and outlines the current methods to the solution. It also defines an overview of the most commonly used valid standards and rules for calculation. Subsequently, some specific examples of defects of flanged joints from practice are demonstrated. Based on these examples, the following is a list of certain limitations that given by standardized rules. In the next part of dissertation is specified own methodology to solving the problem. Here, it is primarily aimed at the mentioned limitations of standard compared to the complexity of reality. Based on these limitations, a certain possibility of optimizing the calculation methodology is subsequently proposed. The idea of this calculation optimization is based on the combination of three different methods of the solution. These are the experimental, numerical (FEM) methods and methodology of calculations defined by a specific valid standard. Much of the thesis is therefore focused on a detailed description of these approaches. Primarily, it is a description of gradual development and improvement in the issue. In the conclusion, the expected progress into the future and a list of results performed so far and publishing activities are also described.
