| Abstract: | The corrosion characteristics of transmission iron tower in Tongqing area of Zhuzhou city are analyzed. SO2 acidic gases are a key factor for transmission iron tower corrosion. The corrosion points originate in zinc coating defects and corner site of tower material, and the improper selection of anti-corrosion painting and inappropriate brushing teehnique will accelerate corrosion. In order to standardize the work of the corrosion protection, the tower general requirements of corrosion protection, corrosion evaluation criteria, technical requirements of tower transformation and painting selection standard are proposed in the article. |
