| 摘 要： | 对API（美国石油学会）油管腐蚀失效事故进行了系统调查，结果表明,API油管接头腐蚀严重区域集中在油管接头现场上扣端外螺纹接头内壁位置，油管腐蚀既与流体冲刷有关.也与CO2腐蚀有关.经过试验研究，认为API油管接头中部的凹槽位置产生了紊流和剪切应力，腐蚀最严重的区域紊流和剪切应力最严重.为解决结构突变导致的腐蚀集中问题，建议油田使用接头内壁平齐的特殊螺纹接头油管.

| Abstract: | This paper reports on an analysis of corrosion failure for API(America Petroleum Institute)tubing,based on field survey,macro-and micro corrosion morphology analysis and material testing.It concludes that the failure fo API tubings was caused by erosion-corrosion.Analyzing the configuration of the API tubing connection,authors further determined that the erosion-corrosion was caused by the severe disturbed liquid and high shear stress at middle of the connection where there is an inside groove.It is suggest... |
