Abstract The integrity assessment of high pressure steam pipeline primarily requires stress state determination, including not only effects of working pressure and temperature, but also all acting loads. Toward this aim, the application of numerical methods for calculating the stress state is the best option. Here, the integrity assessment of one of the collectors of the RA line at Block 1 of ‘Nikola Tesla’ B Thermal Power Plant is shown, which was the subject of reconstruction due to a manufacturing defect in one of the welded joints. Integrity and risk of the steam line is assessed using fracture mechanics parameters, including microstructural analysis. Keywords: steam line, pressure vessel, stress analysis, microstructure, structural integrity |
