【摘要】：目的驗證陰極保護系統(tǒng)在保護目標管道的同時對臨近管道造成的雜散電流腐蝕,對比柔性陽極與陽極地床在保護管道的過程中產生的雜散電流污染情況,確定同溝鋪設的不同管道聯(lián)合保護方案。方法通過同一排流設備對相同區(qū)域的不同管線進行統(tǒng)一保護,陰極保護系統(tǒng)中的接地裝置作為唯一的陽極,多條埋地管線作為電化學電池的陰極實現(xiàn)保護。結果陽極地床產生的雜散電流干擾明顯強于柔性陽極材料;排流保護中,兩條20 m埋地金屬管道達到排流保護的范圍時,柔性陽極的排流電壓為1.2~1.52 V,遠小于碳鋼陽極地床的3.5~15 V,能夠有效減少防護過程中電能的使用。結論同一陰極系統(tǒng)同時對多條金屬管道或金屬構筑物進行排流保護的措施可行。
[Abstract]:Objective to verify the stray current corrosion caused by cathodic protection system while protecting the target pipeline, and to compare the stray current pollution caused by flexible anode and anode ground bed in the process of protecting pipeline. Determine the joint protection scheme of different pipelines laid in the same ditch. Methods different pipelines in the same area were protected by the same drainage equipment. The grounding device in the cathodic protection system was used as the unique anode, and several buried pipelines were used as the cathodic protection of electrochemical batteries. Results the stray current interference caused by anode ground bed was obviously stronger than that of flexible anode material. In discharge protection, when two 20 m buried metal pipes reach the range of drainage protection, the discharge voltage of flexible anode is 1.2 鈮，
