高频焊接石油管的生产工艺探索

摘要

高频焊接石油管，主要应用在油田石油钻井，受力复杂，其化学成分、机械性能必须符合API5标准规定．针对J55、N80级钢，Φ73×5.5 mm、Φ139.7×7.5 mm高频焊接石油管的生产工艺进行了探索，制订了技术参数以及解决了实际生产中的技术难点．产品最终达到API5 CT标准并满足了油田的使用．%High-frequency-welding oil pipe is mainly used in oil field drilling.With complex loading,its chemical composition and mechanical properties must meet API5 standards requirement.In this article,the production process of J55 N80 steel grade,Φ73×5.5mm andΦ139.7×7.5mm is ex-plored and the technical parameters are formulated,which solves the technical difficulties in prac-tical production.The products eventually reach the API5CT standards and meet demands of using in oil-field.
