1、表面技術(shù)第44卷第11期112SURFACETECHNOLOGY2015年11月管道內(nèi)防腐技術(shù)現(xiàn)狀與研究進展趙帥,蘭偉(重慶科技學(xué)院冶金與材料工程學(xué)院,重慶401331)摘要:介紹了石油管道內(nèi)溶解氧、二氧化碳、硫化氫、以及二氧化碳和硫化氫協(xié)同腐蝕的機理。綜述了油氣管道內(nèi)防腐技術(shù),現(xiàn)階段主要的處理方式是選擇耐蝕金屬材料或非金屬材料、添加緩蝕劑、涂層防腐和襯里防腐。分析了各種內(nèi)防腐技術(shù)的優(yōu)缺點,認為管道內(nèi)防腐在未來的發(fā)展方向是將基材選擇、添加緩蝕劑、內(nèi)涂鍍層和內(nèi)襯里技術(shù)進行綜
2、合,以減緩管道內(nèi)的腐蝕。低碳鋼表面鍍鎳層自納米合金化技術(shù),即是集中內(nèi)防腐技術(shù)的綜合運用,得到了表面無縫冶金結(jié)合的高耐蝕性能管材,是未來發(fā)展趨勢的代表。關(guān)鍵詞:管道;防腐;耐蝕材料;緩蝕劑;涂層;鍍層;襯里中圖分類號:TG174.4文獻標識碼:A文章編號:1001-3660(2015)11-0112-07DOI:10.16490/j.cnki.issn.1001-3660.2015.11.018PresentStatusandResearchProgressofAnti-corrosionTechnologyinPipelineZHAOShuai,LANWei(Scho
