Abstract

Abstract

The wall-thinning problem of carbon steel pipes causes great attention at present because of the accidents happened in nuclear power plants.This paper introduces the wall thinning research of carbon steel pipes in the conventional island of a nuclear power plant.Operation condition analysis,chemical composition analysis,metallic phase analysis,micrographic examination,and XRD analysis are performed.According to the analysis above mentioned,the reasons of carbon steel pipes wall-thinning in this nuclear power plant are erosion-corrosion,cavitation,and flow accelerated corrosion,respectively.
