针对胜利石油管理局稠油热采注蒸汽管道和炉管腐蚀爆裂现象严重的问题 ,在分析了注蒸汽管道和炉管腐蚀爆裂原因的基础上 ,提出用 1 5CrMo无缝钢管代替原材质为STB42和ST45 .8/Ⅲ的钢管 ,以减缓注蒸汽管道和炉管的腐蚀。并通过 1 5CrMo钢的性能分析和实际应用效果 ,证明了 1 5CrMo无缝钢管作为注蒸汽管道和炉管具有机械性能高、可焊性好、耐腐蚀、使用寿命长、经济效益好等优点
Aiming at the serious problem of steam pipe burst and tube burst of heavy oil thermal recovery steam injection in Shengli Petroleum Administration, based on the analysis of the reason of corrosion and burst of steam injection pipe and furnace tube, it is proposed to use 15CrMo seamless steel tube instead of STB42 And ST45 .8 / Ⅲ steel pipe to ease the steam injection pipe and tube corrosion. Through the performance analysis and practical application of 15CrMo steel, it is proved that 1 5CrMo seamless steel pipe has the advantages of high mechanical properties, good weldability, corrosion resistance, long service life and good economic benefits as steam injection pipe and furnace tube
