摘要: 腐蚀监测技术是指测试设备正常运行时的内部腐蚀或破坏情况,以避免重大事故发生,延长设备寿命,使生产设备能更有效的运行。以通用微型计算机、调制解调器、可编程逻辑控制器(FX-2N)、信号变送器、腐蚀探针为硬件核心,以虚拟仪器编程环境LabVIEW为软件平台,开发设计了管道内腐蚀监测系统。该系统通过电阻(ER)腐蚀探针、线性极化电阻(LPR)腐蚀探针监测设备内部的电化学腐蚀程度、氢脆趋势,评价缓蚀剂效果。应用该系统对川西北矿区部分管道进行了腐蚀监测,现场监测结果表明,该系统能对管道内腐蚀情况进行高效、可靠的在线监测。

Abstract: Corrosion monitoring technology is used to test the inner corrosion or destruction of device, under the proper operation, to avoid the fatal accident, extend device’s life-span, make de-vice work effectively. The pipeline inner corrosion monitoring system was developed and designed as the hardware core of mi-crocomputer, modem, programmable logical controller, signal
transfer device, corrosion probe and as the software platform of the virtual instrument language LabVIEW. The system can be used to evaluate the effect of anti-corrosion by the electronic re-sistance corrosion probe and linear polarization corrosion probe in the light of the inner electrochemistry corrosion degree and hy-drogen brittle tendency. The system was used in the northwest
of Sichuan diggings. The results show that the effective, reli-able online monitoring of the inner pipeline corrosion can be run by this system.

Key words: virtual instrument control, pipeline corrosion, long-distance monitoring
