Abstract
In the assessment of the remaining service life and analysis of the integrity of pressure equipment, which is composed of complex geometrical configurations, the most important matter is to establish the critical locations from the aspect of possible failure. The Project “Pressure equipment integrity under simultaneous effect of fatigue loading and temperature” will review two types of materials used for the pressure equipment in our industry. These are high-strength low-alloy steels and creep-resisting steels. The specimens made of these two materials will be tested under conditions of the low-cycle fatigue during the simultaneous effect of low or elevated temperature. Final element method (FEM) will be applied for determination of the fracture mechanics parameters in the structure elements which sustained the initial damages. The majority of pressure plant structures is constructed by welding. The focus of the Project will especially be directed to the welded joint cracks. Bearing in mind the nature of the steam line loading, the behavior of the heat-affected zone of the welded joints will be tested on smooth specimens, notched specimens and crack specimens. The measures to be undertaken during the assembly or reparatory welding in order to avoid the type IV cracking will be recommended.
