Abstract:
AbstractHot-dip galvanized coatings represent a protection based on passivation of the single zinc layer. It is one of the most commonly used surface treatments of steel. However, pure zinc forms merely an insignificant upper layer. Coating crosscut is formed by intermetallic phases that can cause decrease in the level of anticorrosion protection. This results from an iron diffusion from the base material. Goal of this paper is to analyse the changes in the mechanical properties of these phases in relation to zinc coating heat treatment. For the experiment, annealing temperatures of 200 °C and

Abstract:
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

Abstract:
This Master’s thesis deals with flange joints. A suitably designed flange joint (FJ) construction and installation is necessary to ensure the reliability of piping systems and machinery where these joints are used. The thesis describes the procedures of their design and assessment in terms of tightness, strength and durability. It focuses on the stiffness calculation of all components of FJ – primarily the stiffness of flanges, bolts and seals. The main part of the work was to create a computational program by using the Python language to determine the appropriate preload force in the bolts. T

Abstract:
The aim of this thesis is to address issues concerning the sealing of the lid for the primary collector within the steam generator (SG) of the nuclear power plant VVER 440. These steam generators are sealed in the original design by nickel rings. Modifying the existing method of sealing by a new type of sealing material, primarily from expanded graphite, can significantly reduce the pressure in the sealing surface and also stress in bolts and flanged joints. The new solution of sealing between the joint of collector and the lid should extend the life of joints and thus the nuclear and technica

Abstract:
The main purpose of this thesis is the modification of the original flange gasket of the VVER1000 pressurizer manhole. Then the construction and function of the pressurizer itself is described, together with detailed calculations of the original and new modified gasket to meet the ČSN EN 1591 standard together with a description of the legislation that has to be followed in the calculations. The comparisons of both gasket types together with main conclusions are placed in the last section of this thesis.
