管束的纵向损伤及其防护技术研究现状
Research status of longitudinal damage of tube bundle and its protection technology
摘要
Abstract
Regarding the problems of the damage to tube bundles caused by longitudinal load and the deficiency of its protection technology,by citing the relevant research findings of predecessors,the instability situations of tube bundles during withstand pressure tests were listed.The impact damages during different processes such as unit startup and shutdown,operation,and online purging and flushing were analyzed,and the failure cases in recent years were used to verify.The hidden longitudinal instability phenomenon that emerges in the structural deformation characteristics of each case was pointed out,the technical countermeasures for preventing longitudinal deformation of tube bundles were proposed,including optimizing traditional structures and developing innovative structures.The innovative structures of tube bundles include structurally enhanced composite tubes,dual support plates for additional protection,and double-ended tie rods for in-line reverse purging.The research results provide new ideas for deepening the understanding of tube bundle vibration,improving anti-vibration measures for tube bundles,and avoiding equipment failure.关键词
