摘要
低周疲劳是连续管的主要失效形式,疲劳评价对连续管的应用起着至关重要的作用。介绍了连续管的工作过程,对比分析了已有的几种连续管低周疲劳试验装置。美国Southwestern PipeInc.试验装置适用于连续管制造过程中对产品质量的检测,美国Tulsa大学及Stewart & Steven-son公司试验装置适用于科研单位对连续管低周疲劳寿命的研究。
The low-cycle fatigue is a main failure form of coiled tubing, and fatigue evaluation played a vital role of coiled tubing application. This paper introduced a coiled tubing procedure and several low-cycle fatigue testing equipments of coiled tubing were compared. The testing equipment of Southwestern Pipe Inc. is suitable for the monitoring of fabricating tubing stage, and the testing equipment of the USA Tulsa University and Stewart ＆ Stevenson Inc. are suitable for the scientific institute to research the low-cycle fatigue life of coiled tubing.
