Popis: | The field investigation, macro-inspection, thickness measurement, chemical components examination, mechanical characters tests, microstructure, SEM, XRD analysis and soil composition test were carried out, in order to analysis the external corrosion of the L415 pipe line near the compressor outlet. The results showed that the frequent vibration of the compressor outlet could lead to the damage and failure of the anticorrosive layer, which made the steel pipe loses protection and further exposed to the external environment to cause oxygen corrosion. The content of Cl- in soil was higher in the western China, which accelerated the corrosion of pipe. The corrosion acceleration mainly depended on the pipeline temperature and the secondary external anticorrosive layer. |
