す。2. Description of the Related Art Conventionally, flange fittings have been attached to the end of a core tube by various methods. (1) For example, as shown in FIG. 1, at room temperature, the outer diameter of the core tube 1 of the composite porcelain pipe is made smaller than the inner diameter of the insertion hole of the flange metal fitting 2, and the core tube of the composite porcelain pipe is inserted into the insertion hole of the flange metal fitting. When assembled, 0.5 mm-2 between the core tube of the composite porcelain tube and the insertion hole of the flange fitting.
A gap g of about mm is created so that the gap g
The resin is poured into and the resin 3 is cured to bond them. (2) Further, as shown in FIG.
When the outer diameter of the core tube 1 of the composite porcelain pipe is made slightly smaller than the inner diameter of the insertion hole of the flange metal fitting 2 and the core cylinder 1 of the composite porcelain pipe is assembled in the insertion hole of the flange metal fitting 2, the core cylinder 1 of the composite porcelain pipe and the flange 0.1mm-0.5mm between the insertion hole of metal fitting 2
Allowing a certain gap g, applying resin 3 to the outer peripheral surface of the core tube of the composite porcelain tube and the outer peripheral surface of the insertion hole of the flange metal fitting, and then attaching the core cylinder to the insertion hole of the flange metal fitting to cure the resin. Join the two by. (3) Alternatively, as shown in FIGS. 3A to 3C, at room temperature, the outer diameter of the core tube 1 of the composite porcelain tube is made slightly larger than the inner diameter of the insertion hole of the flange fitting 2. After heating the flange metal fitting 2 to make the inner diameter of the insertion hole of the flange metal fitting 2 larger than the outer diameter of the core tube of the composite porcelain pipe, the outer peripheral surface of the core cylinder 1 of the composite porcelain pipe and the inner peripheral surface of the insertion hole of the flange metal fitting 2 The resin 3 is applied, the core tube is attached to the insertion hole of the flange fitting, and the resin is cured to bond the two.

Depending on the method, there is a limitation that a resin having a low viscosity must be used for pouring, and it takes a long time to cure and adhere the resin such as preventing outflow. Further, since the core tube of the composite porcelain tube and the flange fitting must be fixed to each other while the resin is cured and bonded, the workability of bonding and the subsequent handling are also inferior. Further, since the gap g is large, peeling is likely to occur due to the difference in expansion between the core cylinder and the flange fitting, which is not suitable for applications in which airtightness is expected. On the other hand, in the method (2), there is no limitation that a resin having a low viscosity must be used, and since the gap g is smaller than that in (1), a slight improvement can be made in terms of peeling. But,
Other drawbacks of the method (1) are not solved. Also,
The method (3) greatly improves the airtightness associated with the occurrence of peeling due to the difference in expansion, but the drawback of the method (2) cannot be eliminated.

れる。According to the method of press-fitting and joining the core tube of the composite porcelain tube and the flange fitting of the present invention, since the core tube of the composite porcelain tube is inserted into the flange fitting by press fitting, the core tube is inserted into the flange fitting after the press fitting. It is fixed axially and circumferentially. Therefore, it is not necessary to fix the core tube and the flange metal fitting of the composite porcelain tube to each other while the resin is cured and adhered, and the labor and the device for ensuring the assembling accuracy are unnecessary. And since it can be handled in an uncured state, it can be immediately transported to the next process, improving efficiency. Also, at room temperature before press fitting and joining,
The outer diameter of the core tube of the composite porcelain tube is larger than the inner diameter of the insertion hole of the flange fitting, and when it is considered as free expansion even when it is heated to the expected maximum operating temperature, the outer diameter of the core tube of the composite porcelain tube is the flange fitting. Since it is set to be larger than the inner diameter of the insertion hole, no peeling stress is generated between the core cylinder and the flange metal fitting in the entire usage area of the composite porcelain tube, and the press-fit joint state can be maintained well. Further, since the core tube and the flange fitting are bonded together by adhesion, the synergistic effect makes it possible to realize stronger press-fitting of the core tube and the flange fitting. Further, according to the press-fitting method of the present invention, a circumferentially extending resin holding portion for holding the resin is provided on at least one of the outer circumferential surface of the core tube of the composite porcelain tube and the inner circumferential surface of the insertion hole of the flange fitting. Provide and apply resin to at least the holding portion side. The applied resin is surely held by the resin holding portion, whereby the flange fitting and the core tube of the composite porcelain tube are surely bonded and joined to each other by this resin.

In the meantime, it is not necessary to fix the core tube and the flange metal fitting of the composite porcelain tube to each other, and the labor for securing the assembling accuracy is unnecessary. Further, the press-fitting and joining state of the core tube and the flange fitting can be maintained well in the entire usage area of the composite porcelain tube. Furthermore, since the core tube is joined to the flange fitting by the two joining methods of press fitting and bonding,
The synergistic effect makes it possible to secure the mechanical strength and airtightness required for the composite porcelain tube. Further, at least one of the outer peripheral surface of the core tube of the composite porcelain tube and the inner peripheral surface of the insertion hole of the flange fitting is provided with a resin holding portion for holding resin, and at least the resin holding portion side is provided with a resin holding portion. Since the resin is applied, the resin is reliably held by the resin holding portion. As a result, the flange fitting and the core tube of the composite porcelain tube are more surely bonded and bonded to each other by this resin. This is because if there is a resin holding part, it will be replenished even if the adhesive resin becomes partially thin due to friction between the core cylinder and the flange metal fitting during press fitting,
This allows for uniform adhesion. Furthermore, the resin holding portion and the opposing portion thereof are adhered to each other.
