| 目的 提出一种判别交流干扰腐蚀风险的方法。方法 根据现场测试参数、土壤理化性质参数及室内模拟腐蚀试验，运用灰色关联分析和三角模糊层次分析，将长输油气管道沿线土壤环境和沿线阴极保护状态等因素与交流干扰腐蚀相结合，确定影响交流干扰腐蚀各关键因素的贡献权重。结果 参考现行土壤腐蚀性以及交流干扰评价的标准，将土壤腐蚀性、交流干扰电流密度、防腐层破损面积以及运行年限进行综合考虑，建立了一种融合交流干扰及土壤腐蚀性评价的交流干扰腐蚀风险识别方法。结论 通过现场应用，该方法评价结果与管道内检测结果一致。 |
| 英文摘要: |
| The work aims to put forward a method for AC interference corrosion risk assessment. According to field test parameters, physical and chemical property parameters of soil and corrosion test results, GRA and FAHP were used to combine the soil environment and the cathodic protection state along the oil and gas pipelines with the corrosion rate of AC interference. The contribution weight of each key factor affecting AC interference corrosion was determined. Referring to the current standards of soil corrosivity and AC interference assessment and comprehensively considering soil corrosivity, AC interference current density, damaged area of coating and operation life, an AC interference corrosion risk identification method integrating AC interference and soil corrosivity assessment was established. Its application on site shows that the assessment results of this method are consistent with the internal detection results of pipelines. |
