流速对油管用N80钢CO2腐蚀行为的影响
Effect of Flow Rate on CO2 Corrosion Behavior of Pipeline Steel N80
摘 要
采用高温高压反应釜进行腐蚀模拟试验,采用失重法、SEM等手段研究了流速对N80油管钢CO2腐蚀行为的影响。结果表明,N80油管钢在100 ℃,0.6 MPa CO2分压时随流速的增大,腐蚀速率几乎呈指数形式增加。低流速时,N80钢腐蚀以全面腐蚀形态为主,流体冲刷的作用有限,但当流速增加以后,局部腐蚀形态愈发明显,流体冲刷显著加剧局部腐蚀的作用。

Abstract
High temperature and high pressure corrosion environments were stimulated using a autoclave, and the effect of flow rate on corrosion behavior of N80 steel was studied by SEM, weight loss method and so on. The results show that the corrosion rate of N80 steel increased exponentially with the rise of flow rate at 100 ℃, 0.6 MPa CO2 partial pressure. The corrosion type of N80 steel was mainly general corrosion when the flow rate was low, and the role played by fluid erosion was quite limited. But the corrosion type of N80 steel changed into localized corrosion at high flow rate, the localized corrosion was markedly accelerated by fluid erosion.
