Structural design of the high-pressure separator with focus on the flange connection
Šmarda, Radek ; Klučka, Ivan (referee) ; Lošák, Pavel (advisor)
The first part of the diploma thesis deals with research in the field of design of process apparatuses. The research continues describing the function, division and main parts of separators. The research part ends with a more detail overview of flange connections. The second part deals with the design and control calculations of the separator using ČSN EN 13445-3 with tightness-strength calculation of the main flange join using ČSN EN 1591-1. At the end of the second part, partial calculations are performed using finite element method in the ANSYS Workbench R2 program, which aim to verify the required tightness of the joint and describe the effect of the bolts tightening procedure on the gasket.

Static Analysis of Parts of Thermoplastic Pipe Systems
Plášek, Jan ; Kuklík,, Pavel (referee) ; prof. Ing. Alois Materna, CSc., MBA (referee) ; Kytýr, Jiří (advisor)
Thermoplastic materials have significant nonlinear behaviour. The nonlinear behaviour is described by creep curves. The curves of creep modules are dependent on stress, temperature and time. The dissertation thesis deals with the approximation of the creep modules by Prony series. Subsequently three procedures are proposed to take account of creep modules. The proposed procedures are used in two applications. The first application deals with the ring stiffness value of a corrugated sewage pipe. The ring stiffness value is influenced by the creep modulus. The other one deals with a thermoplastic flange connection. The clamping force is dependent on the creep modulus of thermoplastics. The problems were solved by ANSYS program system.

Modelling of pressure equipment bolted flange connections
Kolátor, Matyáš ; Pernica, Marek (referee) ; Létal, Tomáš (advisor)
The bachelor thesis deals with computational modeling of flange connections. Due to its separability, bolted flange connections are a frequently used in piping systems or pressure vessels. For the right functionality of the connection, it is necessary to ensure the required tightness. In order to be able to describe the tightness, it is necessary to know the stresses and deformations in all parts of the connection. These days, standard calculation methods are at a high level of accuracy, on the other hand, in order to achieve this accuracy, they have to follow a lot of corrections, in which the original model based on the strength of material theory should be lost. The aim of bachelor thesis is to create computational models based on the strength of materials theory. Computational models are created to illustrate the application of strength of materials theory. At the end of the thesis, the results using several models will be summarized and compared.

Comparison of flange connections design
Hrbáček, Jan ; Dohnal, Miloslav (referee) ; Buzík, Jiří (advisor)
Flange connections are type of connections frequently used in industry. There are hight claims for their dimensioning, strength and tightness. The proper and exact design can be made by calculation or by choice of standardized components (flanges, bolts, nuts etc.) accordig to requirements established by standart. This Bachelor´s thesis occupies itself with qualitative comparison of proposals for the strength design of flanged conections according to ČSN EN 13445, AD 2000 Merkblatt and ASME Code standarts. The programming language called Python is used in this Bachelor´s thesis.

Stress and deformation analyses of the flange connection
Lehnert, Ondřej ; Profant, Tomáš (referee) ; Fuis, Vladimír (advisor)
This master thesis deals with analytical calculation of the various flange connections using theory of thin-walled bodies and axisymmetric assumptions. The calculation is demonstrated by one specific geometry configuration. Numerical finite element method was performed to verify analytical calculation model and also this method enabled more in-depth analysis of the prying effect which has negative influence on the bolt connection tensile load. Output from this analysis is prying point location function in plate thickness dependence and application this function into analytical calculation.
