摘要
叙述了采用漏磁法和超声波法进行钢管检测的基本原理和国内外的应用情况。这两种方法钢管检测的特定环境条件下具有不同的特性、优缺点及适用范围。在对钢管检测技术研究应用和设备的开发过程中,应充分考虑到不同方法的适用性。
The basic mechanism of inspection with the MFL （ Magnetic Flux Leakage） and ultrasonic methods and the application at home and abroad are described. These two methods have their different features, such as, advantages and disadvantage, and different application ranges. When the steel tube inspection is conducted under particular environmental conditions, the suitability of different methods should be fully considered in the research, development and application of steel tube inspection tech- niques.
