摘要
清管器(PIG)是清理管道的有效工具之一,该技术始于20世纪60年代,是一项由防腐专业引申为管道防护、维持的技术。文章对PIG清管器关于解决卡堵问题的专利技术发展路线作了相应分析,重点对其各分支的技术发展方向和技术手段的发展脉络进行了梳理。
PIG（PIG） is one of the effective tools to clean up the pipeline, which began in the 1960s and is a extension from anti-corrosion profession to pipeline protection and maintaining technology. From the perspective of patent, this paper makes a corresponding analysis on PIG patent technology development routes of solving the plugging, and focus oncombing the development context of technical direction and technical means of the technical branches.
