It should be noted that, during the process of stretching the second pipe 20 by using the movable flange 40, the first pipe 10 of the present embodiment may also be deformed following the deformation of the second pipe 20, or only the first pipe 10 is stretched and deformed, and the second pipe 20 is not deformed, and thus will not be described herein.
In the present embodiment, the flange mounting method of the present embodiment further includes:
firstly, the taper sleeve 50 is put between the second pipeline 30 and the first pipeline 10, the taper sleeve 50 is partially inserted into the pipe orifice 31 of the second pipeline 30, and then the sealing gasket 80 is put between the taper sleeve 50 and the fixed flange 20. That is, in the present embodiment, in addition to the requirement that the taper sleeve 50 and the seal gasket 80 are inserted into the gap between the first pipe 10 and the second pipe 30, the gap between the first pipe 10 and the second pipe 30 can be set sufficiently small, and finally the second pipe 30 can be deformed by stretching, so that the assembly sealing between the movable flange 40, the taper sleeve 50, the seal gasket 80, and the fixed flange 20 is achieved, and the assembly sealing between the first pipe 10 and the second pipe 30 is achieved.
