| Abstract: | Several failure resulted from corrosion perforation occurred in tubes in heat exchanger have found in inspection in one petrochemical cooperation.The eddy current examination for tube bundle in heat exchanger was carried out.By using direct spectrum meter and 3-D microscope,the material of failed tube and concave surface were observed and examined.The composition of process water was also examined by using ion chromatogram meter and mass spectrum meter.Then,the broken edge and the hollow in tubes were analy... |
| Keywords: | failure analysis heat exchanger local perforation corrosion under scale |
