摘要
在对某核电厂重要厂用水系统的不锈钢支管进行腐蚀检查过程中,发现支管的不锈钢法兰面存在严重腐蚀,本文从不锈钢在海水中的局部腐蚀形式及机理两方面对不锈钢法兰面腐蚀原因进行简要分析,并提出了降低或避免法兰面腐蚀风险的防腐措施及方法。
During corrosion inspection for the stainless steel branch pipe of Essential Service water System in a nuclear power plant, It was founded that the Flange of the branch pipe were serious corroded. The cause which is the corroded stainless steel flange was Briefly analysed by Forms and mechanism of stainless steel local corrosion in seawater, The measures and methods were advanced to reduce or avoid the corrosion risk of stainless steel flange in this artide.
