部を得ることは尚一層困難である。(Prior Art and Problems to be Solved) Ceramic tubes and metal tubes are increasingly being used in conjunction with each other in piping and the like that require partial heat resistance. In such cases, conventionally the ceramic tube 12 and the metal tube 14 have been brazed directly in a vacuum as shown in Figure 2, but since ceramics are brittle, brazing may occur due to differences in heat and expansion. Connections are prone to damage due to strain forces. On the other hand, as shown in FIG.
3, the joint 15 of the umbrella-shaped thin metal plate 11b and the metal tube 14 is joined by vacuum brazing as before, and is opposite to this.
For example, in TIG welding, plasma welding is performed, and the umbrella-shaped metal thin Fj, lla and 11b are brought into contact with each other at their peripheral edges 16, and an expansion pipe joint that is TIG or plasma welded is used to connect a ceramic pipe and a metal pipe. A method has been proposed to provide a helical joint between thin plates, but it is technically difficult to weld helical joints of thin plates.
In particular, in the case of aluminum thin plates, it is even more difficult to obtain a welded part with high airtightness.

の他の方法を用いることができる。The ceramic tube and the metal bellows are preferably joined by a conventional vacuum brazing method, and the joining end of the ceramic tube is preferably subjected to a customary metallization treatment to facilitate the joining. However, the joining of the ceramic tube and the metal bellows is not limited to brazing, and any other suitable method may be used, such as diffusion bonding, as long as it can prevent damage to the joint.
金属管と金属ベローズの溶接には770等公知の溶接法

実用上の効果はきわめて大きい。General welding can be applied to join the metal pipe and metal bellows, and automatic welding can prevent defects such as leaks and increase the reliability of the joint. Also, by making the metal bellows thin and having a sufficiently large number of threads, the shadow K of welding heat can be prevented. Moreover, since the metal rose is used as an expansion pipe joint, the shape of the connection part is WJ.
Since it is simple and has no protruding parts, it has extremely great practical effects, such as allowing piping to be installed in narrow spaces.
