Sažetak
Thermal stress can cause problems while designing power plants, especially steam boilers. The standards for calculation of the boiler pressure parts mostly determine only the calculation procedure for overpressure load. Other load influences, including the influence of thermal dilatation on the stress values in the boiler structure, should be dealt by the designer. The aim of this work is to present the whole procedure of stress / strain calculation in the steam boiler pipe. The stressed state in the pipe is the result of thermal dilatation differences. The analytical calculation for linear-elastic behaviour of the material was created, together with numerical one, where bilinear yield law of the material was supposed.
