管道带压开孔的残余铁屑回收装置开发
Development of Residual Iron Scrap Recovery Device with Hot-Tapping

带压开孔是钢制油气管道常用的维抢修方法，该方法因采用机械刀具来切管，不可避免的会产生残余铁屑，随着油气管道长久运行，其内的铁屑对油气介质的纯净度和管道上阀门的开关都有较大影响。本研究通过借用磁力吸附原理，研发出带行走轮的折叠旋转磁吸式铁屑回收装置，通过多次测试改进，圆满的解决了带压开孔后残余铁屑回收的难题，从安全性上提升了油气管道维抢修作业与后续运营维护间的谐和度。
Hot-tapping is a common maintenance repair method for steel oil and gas pipelines. This method is the mechanical tool cutting pipe, which will inevitably produce residual iron scraps. With the long operation of oil and gas pipelines, the iron chips in it have a great impact on the purity of the oil and gas medium and the switch of the valve on the pipeline. In this study, a folding and rotating magnetic iron scrap recovery device with walking wheel was developed. Through many tests and improvements, the problem of residual iron scrap recovery after pressure hole opening was suc-cessfully solved, and the harmony between oil and gas pipeline maintenance and repair operation and subsequent operation and maintenance was improved in terms of safety.
