摘　　要：借助埋地管道防腐层不开挖检测技术,对秦山第三核电厂2台机组BOP区域埋地管道的外表面防腐层状态进行了检查和综合评价。检查评价结果认为土壤环境腐蚀性弱、防腐层状态总体一般,并给出了后续处理建议。With the help of Indirect Nondestructive Testing Technique for pipeline anticorrosive coating,the condition of anticorrosive coating of buried pipelines in BOP area of two units was checked and evaluated comprehensively.It was considered that the corrosion of the soil environment is weak,and the anticorrosive coating is generally in general condition,and subsequent treatment suggestions were given.
