管道内壁缺陷无损检测技术

Nondestructive Testing Technologies for the Inner Defect Detection of Pipeline

介绍了管道缺陷无损检测的常用方法(如射线检测、超声检测、涡流检测和基于光学原理的检测技术)及其原理和各自的优缺点。指出各检测方法均有自身的独特性,当仅用一种方法不能得到理想的检测结果时,需多种方法结合使用。

The common nondestructive testing technologies for pipeline such as radiographic testing, ultrasonic testing, eddy current testing and optical testing were introduced. The principles and methods were described emphatically and the advantages and disadvantages of each method were given. At last, a conclusion was drawn that each testing method could not meet the pipeline testing requirement entirely, and it should be integrated to compensate each other＇s shortcomings.
