Strength calculation of high-pressure steam piping according to EN 13480
Řezník, Dominik ; Pernica, Marek (referee) ; Létal, Tomáš (advisor)
The Master's thesis deals with the stress and strength calculation of a high-pressure steam piping system, which is part of the steam piping system of a waste-to-energy plant. In the theoretical part of the thesis, basic knowledge about stress and strength and piping systems (pipe support system, types of loads, fittings and other components) is summarized with respect to the used standards. Part of the theoretical section also includes one of the objectives of the thesis, which is to provide basic knowledge about the KKS codes. In the practical part, firstly, using the VVD software, the pipe class is calculated and created in order to design nominal thicknesses of all the pipes and fittings from the piping system. The core part of the work is the performance of the stress and strength calculation in the CAESAR II software, which includes the appropriate setting of the calculation model based on the calculated pipe class and the documentation from the customer, the selection of pipe supports and the adjustment of the pipelines based on the previous and ongoing results. As part of the calculation, the nozzle loads and support loads are also assessed and verified. In the last part of the work, a simplified FEM calculation of the dump-tube (transition component for steam discharge into the condenser) is performed in PRG NozzlePro software. All the modifications are continuously discussed and the results are then summarized.

Analysis of nozzle-to-shell joint connected to the process piping
Ondráček, Marek ; Michálková, Anežka (referee) ; Pernica, Marek (advisor)
The diploma thesis focuses on the stress analysis of the nozzle-shell junction of a pressure vessel loaded with forces and moments from the connected process piping. The diploma thesis provides general information about pressure vessels, nozzles, piping systems, and details the various methods used for the calculations. The computational part of the diploma thesis focus on the stress analysis at the nozzle-shell junction of the pressure vessel, where the analyzed nozzle is connected to the process piping. The piping generates forces and moments on the nozzle, which must be considered in the stress calculations for this junction. The software Caesar II is used to calculate the forces and moments from the piping. For the stress analysis of the junction, the thesis uses several calculation methods, including the Welding Research Council (WRC) guidelines, PD 5500 standard, CSN EN 13445 standard, and the Finite Element Method (FEM). The objective of the thesis is to evaluate the outcomes of each method, compare them, and assess their approaches to calculating the stress at the junction between the nozzle and the shell of the pressure vessel.

Design check calculation of piping according to ASME B31.3
Dohnal, Milan ; Dohnal, Miloslav (referee) ; Létal, Tomáš (advisor)
The thesis is focused on check stress analysis of an already constructed piping system, which constitutes a key element in the transport of process fluids, especially liquids. Properly functioning piping is required to withstand the anticipated loads, both in the test and in the operating conditions. For the resistance assessment, ASME codes were used, especially ASME B31.3, which is widely used in the industry worldwide.

Design of process unit pipeline
Butek, Petr ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
The master’s project deals with the pipeline systems of process unit. The design of the industrial pipeline is usually extensive and complex task interwoven with a lot of technical disciplines. Diploma thesis is focused on the strength calculation of the pipeline specified by the ČSN EN standard. The main goal of the calculation is appraisal of the most stressed parts under operating and testing conditions. The diploma thesis is handled with the key aspects that influence the overall concept of the pipeline design as well as the strength calculation.
