Abstract: A method of forming a tube joint which can be used in a desalination plant includes providing a fluted tube (1), applying a sealant (51) to the tube end (19) and inserting the tube end (19) into a tube sheet or plate (3) to form a joint therebetween. After insertion, the inner surface of the fluted tube (1) is worked to deform external ridges of the fluted tube (1) and uniformly distribute the sealant (51) throughout the joint area. The fluted tube (1) is deformed using a roll expanding method. The fluted design of the tube (1) retains sealant (51) in the joint area during tube (1) insertion and expansion and takes advantage of the heat transfer characteristic of the flutes (9) to provide an improved joint construction especially adapted for heat exchange use.

Abstract translation: 一种形成可用于脱盐装置的管接头的方法包括提供带槽管（1），将密封剂（51）施加到管端（19）并将管端（19）插入管板中或 板（3）以在其间形成接头。 在插入之后，波纹管（1）的内表面被加工以使波纹管（1）的外部隆起变形并且使密封剂（51）均匀地分布在整个接合区域中。 波纹管（1）使用辊式扩张方法变形。 管（1）的凹槽设计在管（1）插入和膨胀期间将密封剂（51）保持在接合区域中，并利用凹槽（9）的传热特性来提供改进的接头结构，尤其适用于热量 交换使用。
