破損する等といった事故が起こりやすい。However, in such a structure, as described above, the outer circumference B of the glass tube B
' is melted and bonded to the inner wall of steel tube A, so steel tube A and glass tube B are completely integrated, so when an external force is applied to steel tube A, it also affects the glass tube, causing the glass tube to Accidents such as damage are likely to occur.

である。In addition, this type of steel pipe is made by inserting a glass tube with both ends sealed inside the steel pipe, then sealing both ends of the steel pipe with a cap, and then putting it in a heating furnace in this state and heating it to the lining temperature. It is then manufactured by cooling at the end.

げられ、その結果ひびが入ったり、破損したりしやすく
なるのである。When the glass tube is placed in a heating furnace and heated, the pressure inside the glass tube increases as the temperature rises, and the softened glass tube expands and comes into pressure contact with the inner wall of the steel tube, and its outer periphery is welded. However, when the glass tube is completely integrated with the steel tube in this way, during the final cooling process,
Glass tubes are more likely to crack or break. During cooling, when the inner surface of the glass tube tries to contract, the outer surface also tries to contract at the same time.
The outer surface is melt-bonded to the inner wall of the steel pipe, which prevents it from shrinking, making it more susceptible to cracking and breakage.

である。``Effects of the Invention'' As described above, the present invention provides a layer of copper, gold, silver, etc., interposed between the inner wall of the steel tube and the outer peripheral surface of the glass tube, thereby preventing melting of the glass tube onto the inner wall of the steel tube as in the conventional method. This prevents integration by adhesion. Therefore, even if an external force is applied to the steel tube, the internal glass tube is not affected because it is a separate body, and even when cooling during manufacturing, the glass tube can freely shrink because it is not integrated with the steel tube. We do not have any problems such as cracking or breakage as in the past.
