摘要
介绍了双壳程U型管换热器的 1种极为少见的失效形式 ,并对失效原因进行了初步的分析 ,从而为这种结构型式换热器的设计。
In the present work, a rarely observed failure mode of dual-shell U-tube heat exchanger was studied, and the preliminary reason of the failure was discussed. It is expected to provide some basis and noteworthy items during designing, manufacturing and using the kind of heat exchanger.
