摘　　要：针对实施常规腐蚀挂片悬挂作业时需要管道停输而影响正常运行的问题,研制了不需停输的管道腐蚀挂片悬挂装置。该装置采用主体填料密封系统与闸板相结合的独特设计,将管道内部介质与外部安全隔离,通过上丝杆机构将腐蚀挂片悬挂至预定位置,在不影响管道正常运行的情况下,快速、便捷地完成腐蚀挂片装卸工作,实现对管道的动态监测。在新疆克拉玛依油田红浅1井区火驱先导试验项目开发区块油气集输管道进行现场应用,结果表明:该装置满足中、低压管道设备的使用要求,且动态装卸腐蚀挂片准确率及成功率高。Shutting down of pipeline is needed when suspension installation of conventional corrosion coupon is carried out.However,this installation operation influences normal running of pipeline.And in this case,a kind of corrosion coupon suspension device without shutting down of pipeline is developed.The device uses a unique design of integrating main packing seal system with gate to achieve safe isolation between internal pipeline medium and external environment,which can suspend the corrosion coupon to a predetermined position with the upper screw rod mechanism and complete corrosion coupon installation and removal rapidly and conveniently under the condition normal running of pipeline to achieve dynamic monitoring of the pipeline.Field applications are carried out in an oil and gas gathering pipeline in Hongqian No.1 Well in Karamay Oilfield,Xinjiang.Results show that the device can meet the needs of use requirements in low-pressure and medium-pressure pipe equipments with high accuracy rate and success rate under dynamic installation and removal.
