Specifically, when the connecting pipe assembly is required to be used for connection, the pipe body 1 and the expansion structure 2 are inserted into a preset structure (such as a pipeline of a heat exchange pipe), then the outer diameter of the expansion structure 2 is adjusted, so that the outer diameter of the expansion structure 2 is matched with the inner wall of the preset structure in an abutting mode, at the moment, due to the effect of static friction force, the pipe body 1 is relatively fixed with the preset structure, the reliable connection of the pipe body 1 and the preset structure is realized, and meanwhile, gaps existing between the pipe body 1 and the preset structure are filled by the expansion structure 2, so that sealing reliability between the pipe body 1 and the preset structure is realized, and then the preset structure is detected. When the connecting pipe assembly is disassembled, the outer diameter of the expansion joint structure 2 is adjusted again, so that the expansion joint structure 2 is separated from the preset structure, and the pipe body 1 and the preset structure are taken out.
The expansion joint structure 2 comprises an expansion joint shell, wherein the expansion joint shell is arranged on the outer wall of the pipe body 1, the expansion joint shell and the pipe body 1 jointly enclose a pressure cavity 21, a pressure inlet 22 is arranged on the expansion joint shell, and the pressure inlet 22 is communicated with the pressure cavity 21.
