| Abstract: |
| Objective To elucidate the relationship between the corrosion rate of three ferrous metals and the associated soil properties. Methods The weight loss due to corrosion and the pitting depth of Q235B steel, X70 and X80 pipeline steels were analyzed and compared with the composition and the physicochemical properties of soil minerals. Results The worst corrosion of three studied ferrous metals was observed in the red soil in Yingtan, Jiangxi Province. The differences of corrosion rate in the other seven soils were not significant for Q235B steel. The significant larger weight losses of X70 pipeline steel in the non-acidic soils were found in the soils in Daqing and Liaoning, located in Heilongjiang and Liaoning Provinces, respectively. The corrosion rate of X80 pipeline steel in the studied soils followed the order: Yingtan, Jiangxi>Daqing, Heilongjiang>Shenyang, Liaoning=Dagang, Shandong≥Chengdu, Sichuan=Lhasa, Tibet≥Korla, Xinjiang≥Golmud, Qinghai. Conclusion The highest corrosion rate of three ferrous metals in the red soil was most likely resulted from the heterogeneous texture as the high content of clays caused long maintenance of moisture and high soil acidity. |
