Sažetak

A calculation of welded pressure vessels for fire safety is shown in this paper. At the first step, the temperature of the steel walls has been investigated, and the inner liquid pressure and the temperature increase. It is assumed that the safety valve is out of work and cannot reduce the increasing pressure. At the second step, the growing pressure and softening steel represent danger after a critical time. The result will be a safe time when the damage will occur. Three different alternatives have been calculated: the increase of the vessel wall thickness, the increase of the applied steel yield stress, the effect of the thermal coating. The thermal coating was the best alternative. This kind of calculation helps to find the best safe solution.
