在用工业压力管道的无损检测新方法解析

Analysis of New Methods of Nondestructive Testing in Use of Industrial Pressure Pipeline

在用工业压力管道在运行期间存在内腐蚀和外腐蚀等腐蚀缺陷,威胁管道结构的完整性。根据TSG D0001-2009《压力管道安全技术监察规程—工业管道》的要求,应对压力管道进行定期检验,从而发现管道上存在的腐蚀缺陷,减小事故的损失。在对各个无损检测新方法基本原理介绍的基础上,给出了无损检测新方法的关键点解析,最后总结了定期检验中的检验方法,为在用工业压力管道的定期检验提供参考。

There is inside corrosion, outside corrosion and other corrosion defects during operation of industrial pressure pipeline, that will threat the pipeline integrity. According to ＂Pressure pipe safety technology supervision regulation for industrial pressure pipe＂（ TSG D0001 -2009 ） , periodical inspection should be made for the industrial pressure pipeline. Periodical inspection of the industrial pressure pipeline, which reduces the loss of accident, can identify defects and find both inside and outside corroding situations on pipeline. Based on the introduction for the principle of pipeline＇s new methods of nondestructive testing, the advice for key points of every nondestructive testing method was shown. Finally, the testing methods for periodical inspection were summed up, thus providing relevant reference for the periodical inspection of industrial pressure pipeline.
