在我国随着经济发展越来越迅速,天然气的使用也越来越广泛,天然气管道也架设的越来越多,管道内的气压不断的增大,一系列的问题便随之而来,所以天然气管道安全问题也越来越受到相关企业的关注。天然气的管道裂纹无损检测是目前研究的方向,因为在管道腐蚀无损检测技术的完善后人们也发现了更多的管道裂纹的产生方式,本文主要研究X射线技术、电磁超声检测、磁致伸缩导波检测和磁记忆检测技术,这几项检测方法都是先进和优秀的。
In our country, with the rapid economic development, the use of natural gas is also becoming more and more widespread. Natural gas pipelines are also set up more and more. The pressure inside the pipeline is constantly increasing. A series of problems ensue Natural gas pipeline safety issues are also more and more concerned by the relevant enterprises. Natural gas pipeline crack nondestructive testing is the direction of the current research, because in the pipeline corrosion nondestructive testing technology improved people also found more ways to produce pipe cracks, this paper mainly studies X-ray technology, electromagnetic ultrasonic testing, magnetostrictive guide Wave detection and magnetic memory testing technology, these several detection methods are advanced and excellent.
