摘要
输气管道因输送介质含硫化氢、二氧化碳和水等腐蚀介质 ,均存在腐蚀问题 ,特别是在含卤水的积水管段 ,管内壁电化学腐蚀穿孔、管道开裂事故时有发生。本工作选用先进的电化学技术设备 ,应用于输气管道的实时腐蚀监测和防腐蚀技术的评价 ,并与经典挂片法测定的腐蚀速度进行了对比。
There are many corrosion media contained in the natural gas in pipelines, such as H 2S, CO 2 and H 2O etc. Which may lead to various kinds of corrosion. In this work, on-line monitoring of gas pipes and evaluation of the effect of anti-corrosion technology were performed using high-tech electrochemical facilities.
