长久以来,CO_2腐蚀一直是石油工业用材面临的最严重问题之一.大量案例表明60%的海上油气田腐蚀失效是由碳钢的抗CO_2腐蚀性能较差导致的.通过合金化的方法向碳钢中加入少量Cr,进而研发出的低Cr管线钢具有较好的抗CO_2腐蚀性能,比普通碳钢更能适应较为苛刻的介质环境,且机械力学性 For a long time, CO 2 corrosion has been one of the most serious problems facing the petroleum industry timber.A large number of cases show that 60% of the offshore oil and gas fields corrosion failure is caused by the poor corrosion resistance of carbon steel CO_2 by alloying the carbon steel In a small amount of Cr, and then developed a low-Cr steel pipe has better resistance to CO_2 corrosion than the more common carbon steel to adapt to more demanding media environment, and mechanical and mechanical
