影响埋地X70管线钢腐蚀性的土壤因素评价
Evaluation of Soil Factors Influencing Corrosion of Buried X70 Pipeline Steel
摘 要
土壤腐蚀是影响埋地管线能否安全运行的重要因素.通过模糊聚类确定了影响X70和Q235钢腐蚀速率的主要土壤因素,利用灰关联和层次分析等方法确定了各主要影响因素对腐蚀速率的影响顺序和权重大小.计算结果表明:影响X70钢土壤腐蚀性的主要因素从大到小的顺序和权重依次为pH(0.4050)＞含水量(0.2517)＞电导率(0.1493)＞全盐(0.0868)＞Cl-(0.0501)＞NO-3(0.0291)＞SO2-4(0.0173)＞HCO-3(0.0107),影响Q235钢土壤腐蚀性各因素顺序和权重与此相差不大.本结果有助于深化对土壤腐蚀的认识,也为土壤腐蚀性评价方法的制定提供一些新的参考.

Abstract
Soil corrosion is one of the important factors for safe operation of buried X70 pipelines.The main environmental factors of soil corrosion for X70 and Q235 steels were determined using fuzzy clustering,and the order and weight of the main factors were investigated by means of grey relationship analysis and analytical hierarchy process methods.The calculation results showed that the weihgt of factors for the soil corrosion of X70 steel decreased in the following order:pH value (0.4050),water content (0.2517),conductivity (0.1493),salt content(0.0868),Cl-(0.0501),NO-3(0.0291),SO2-4(0.0173),HCO-3(0.0107),and the results for Q235 steel were little different from those.These results provided some new reference data for establishing an evaluation method for soil corrosion of underground pipelines.
