    Abstract

    Impression creep testing was applied in a research project funded by Värmeforsk, Sweden, in order to study the creep rate in a HAZ of a girth weld in a P22 (10CrMo910) power plant piping. In the project a special routine was developed to transfer the results of a global piping stress analysis into a detailed 3D FE model of an individual piping component. In the 3D analysis the real HAZ creep rates were modelled on the basis of the impression creep tests.
