Hi-speed Flux Leakage Detection System Operating with Steel Pipe Rotating and Related Critical Techniques

摘要: 針對(duì)鋼管生產(chǎn)對(duì)高速漏磁探傷設(shè)備日益劇增的需求,從鋼管漏磁檢測原理及方法入手,提出并分析了高速漏磁檢測關(guān)鍵技術(shù)?；谶@些關(guān)鍵技術(shù),開發(fā)出國內(nèi)第一套基于鋼管螺旋運(yùn)動(dòng)、檢測速度達(dá)到2.8m/s的高速漏磁檢測設(shè)備,其檢測指標(biāo)達(dá)到API標(biāo)準(zhǔn)的最高探傷要求,具有較好的使用效果。

Abstract: Addressing the increasingly huge demand for hi-speed flux leakage steel pipe detecting equipment,the coauthors,based on the working principle and method for such equipment,point out and analyze the critical techniques related to the hi-speed flux leakage detection process. With the critical techniques as identified,the first hi-speed flux leakage steel pipe detection system in the country has been developed,which is operating with the pipe rotating spirally,and at a detecting speed up to 2.8 m/s,having resulted in inspection target values conforming to the most stringent NDT requirements as specified under applicable API specification,and brought about satisfactory operation effectiveness.
