Microcor腐蚀监测技术及其应用

Microcor Corrosion Monitoring Technology and Its Applications

腐蚀监测可以在设备正常运行的情况下,测量各种工艺气液流状态的腐蚀性。为了全面认识油气管道腐蚀因素,制定防腐措施,介绍了Microcor腐蚀监测技术的工作原理、技术特点、监测步骤等。通过与挂片失重法、线性极化电阻法、电阻法等常用腐蚀监测技术的比较以及Microcor腐蚀监测现场应用实例,发现Microcor腐蚀监测具有灵敏度高、适用范围广、性能稳定、响应速度快、分辨率高等优点。Microcor腐蚀监测是腐蚀过程监测、腐蚀过程控制,特别是对缓蚀剂效应评价的理想测试技术。

Corrosion monitoring can be applied to measure the process gas and the state of corrosive liquid flow in the case of normal operation. With the purpose of comprehensive understanding of the oil and gas pipeline corrosion factors and the develop- ment of anti-corrosion measures, working principle, the technical characteristic and the monitoring procedures of Microeor corro- sion monitoring are described in this paper. Compared with the commonly used corrosion monitoring technology such as the weight loss method, the linear polarization the resistance method, the resistance probe method as well as the application examples of Mi- eroeor corrosion monitoring, Mierocor corrosion monitoring has the advantages of high sensitivity, wide application, stable perform- ance, fast response and high resolution. Mierocor corrosion monitoring corrosion is an ideal test technology of the corrosion process monitoring and the corrosion process control, especially for the inhibitor effect evaluation.
