Abstract

This paper analyses the distribution of stress through steam line of medium superheated steam with the special emphasis on the critical location, the bend, in order to estimate the remaining lifecycle of a steam line. Moreover it presents the theoretical basis of the beam superelement with 2D cross-section segment which was used for analysis in PAK software. The obtained results of stress analysis and estimated reliability of the construction after 200.000 hours of exploitation are shown.
