Abstract

This paper discusses the importance and complexity prediction of fatigue life in connection with reconstruction or rebuilding of compressor station and in connection with degradation of material and change of its static and fatigue mechanical characteristics. The subject of the research is the piping ring, which was removed above a T-module of a turbocompressor of compressor station. The paper brings partial results of testing and analysis of the macrostructure and mechanical properties of the base material and the material in the weld area of removed piping ring.

Keywords

piping systems; mechanical properties; fatigue fracture; macrostructure
