摘要
针对石化行业中现有的腐蚀监测技术,本文对当前普遍使用的4种技术进行了综述:挂片失重法、电阻探针法、电感探针法、超声波在线测厚技术。重点是前四种腐蚀监测基本工作原理以及它们各自的优缺点。在此基础上,引入近几年发展很快,且综合技术优良的场指纹法(FSM),着重说明工作原理、目前的现场应用情况以及它的特点和局限性。通过对这几种腐蚀监测技术的阐述,为相关企业提供有益的参考。
In the view of existing monitoring techniques in petrochemical industry,the commonly-used techniques are summarizes：Corrosion Coupons,Electrical Resistance Probe,Electrical Inductance Probe and Ultrasonic,which focuses on the working principles and their advantages and disadvantages.On this basis,this paper introduces a monitoring technique with excellent synthesized performance,Field Signature Method（FSM）,which develops fast in recent years：In the review,FSM is focused on the working principle,the current application situation and its characteristics and limitations.The review can provide beneficial reference for the enterprises.
