摘　　要：简要介绍了硝酸生产装置的腐蚀形态及国内外现有的解决方法.用极化曲线方法测定白钢和碳钢管线的腐蚀速率,结合调研结果提出防腐蚀方案设计.Corrosion morphology of steels by nitric acid and methods of corrosion prevention for nitric acid fabrication equipment were introduced in this paper. Corrosion rate of stainless steel and carbon steel was tested by polarization experiments. At last, reasonable protection methods were proposed based on the field investigation.
