摘　　要：国内很多平台已经使用在线腐蚀监测系统,在线腐蚀监测技术的最大优点是“在线”,即掌握即时的腐蚀 速率,并全程追踪设备某一特定位置的腐蚀速率大小或某-特征变量（值、含量等）的变化情况,从而随时 掌握材料、设备的腐蚀状态,预防和控制腐蚀的发生与发展,使设备处于良好的可控运行状态.目前在国内 的海洋平台中多釆用挂片失重法进行监测,但由于监测周期长,误差大等缺点,已经不能满足用户的要求. 特别是对于运行多年的老平台,管道腐蚀比较严重,依靠挂片来监测,存在很大的安全隐患.因此,引进实 时在线监测系统很有必要.而电阻探针法是目前石化行业应用最为广泛的腐蚀监测方法之一,且这种监测方 法也相对比较成熟,它测量简便迅速,信号反馈快且不受腐蚀介质的影响.此外电阻探针可以及时反映出设 备运行过程中的腐蚀变化趋势;On-line corrosion monitoring system has been used on many platforms in China, by which the instantaneous corrosion rate is recorded. At present, on some marine platform, it the weight loss method is still used to monitor corrosion, which has shortcomings such as long monitoring cycle and big errors. Therefore, it is necessary to introduce on-line monitoring system, in which resistance probe is widely used to monitor corrosion. The measurement is simple and rapid, and signal feedback is quick, and is not affected by the corrosive medium. In addition, the resistance probe can reflect the tendency of corrosion in the operation process of the equipment.
