Abstract:

通过恒电位阳极极化和失重法考察了不同pH值、温度和H2S浓度下Q235A钢在弱酸性介质中的氢渗透电流密度与腐蚀速率的变化情况,着重探讨了各影响因素下氢渗透电流与失重腐蚀速率之间的相关性,为氢通量技术用于油气管道非侵入式腐蚀监测提供依据。研究发现:随着pH降低或介质温度升高,Q235A钢的腐蚀速率与氢渗透电流均逐步增大,且二者之间具有良好的线性相关性。随着H2S浓度增加,Q235A钢的腐蚀速率呈现先增大后降低的趋势,但氢渗透电流则先增大而后趋于稳定;当H2S浓度在5~200mg/L范围内,腐蚀速率与氢电流符合二阶多项式函数关系。通过自制的氢通量探针监测实验管道内腐蚀时,发现过厚的管壁降低了氢电流测量灵敏度,但采用恒电位阶跃法得到的氢渗透电量(氢通量)则与失重腐蚀速率之间具有良好相关性,表明渗氢电量法可用于测量油气管道的内腐蚀速率。
