な方法である。Next, the procedure for joining the conventional pipes shown in FIGS. 6 and 7 will be described. First, the first pipe 6 is formed with a hole 8 smaller than the outer diameter of the second pipe 7. A flange 9 is formed at the end of the second pipe 7 so as to follow the outer surface of the first pipe 6. Thereafter, the second pipe 7 is pressed against the first pipe 6 so that the flange 9 is located at a position surrounding the hole 8 formed in the first pipe 6, and the brazing material 10 is used for joining. This joining method is different from the joining method of the pipes shown in FIG. 4 and FIG.
This is a simple joining method in which the rising portion is not machined in the hole 8 mentioned in 1.
発明が解決しようとする問題点 しかしながら、第４図、第５図に示された管の接合方
法では、接合強度を上げるため、第１の管１の穴に立ち
上がり部３を加工し、第２の管２に、第１の管１の立ち
上がり部３に挿入するための端部４を加工するため、製
作工数が多くかかるという問題点を有していた。Problems to be Solved by the Invention However, in the pipe joining method shown in FIGS. 4 and 5, in order to increase the joining strength, the rising portion 3 is processed in the hole of the first pipe 1 and the second portion is formed. Since the end portion 4 to be inserted into the rising portion 3 of the first pipe 1 is processed in the pipe 2 of No. 1, there is a problem that it takes a lot of manufacturing man-hours.
さらに、第１の管１に立ち上がり部３を加工すると
き、第１の管１が変形するという問題点も有しており、
それゆえに第１の管１に十分なの肉厚を有する管を用い
なければならず、材料コストが高くなるという問題点も
有していた。Further, when the rising portion 3 is processed on the first tube 1, there is a problem that the first tube 1 is deformed,
Therefore, a tube having a sufficient wall thickness must be used for the first tube 1, and there is a problem that the material cost becomes high.
一方、第６図、第７図に示された管の接合方法では、
第１の管６と第２の管７との間に位置決め手段を有して
いないため、液体を通過させる第１の管６にあけられた
穴８と、第２の管７に加工されたフランジ９との位置決
めが難しく、フランジ９が穴８の一部を塞ぎ流体の通過
に影響を与える可能性があるという問題点を有してい
た。On the other hand, in the pipe joining method shown in FIGS. 6 and 7,
Since there is no positioning means between the first pipe 6 and the second pipe 7, the holes 8 formed in the first pipe 6 for passing the liquid and the second pipe 7 are processed. Positioning with the flange 9 is difficult, and there is a problem that the flange 9 may block a part of the hole 8 and affect the passage of the fluid.
また、第１の管６の外面に第２の管７のフランジ９を
押しつけてロー材10で接合するので、接合面の間隙を一
定に保持することが難しくロー材10の浸透度を均一にで
きず、強度，気密性で劣るという問題点を有していた。Further, since the flange 9 of the second pipe 7 is pressed against the outer surface of the first pipe 6 and the brazing material 10 is used for bonding, it is difficult to keep the gap between the bonding surfaces constant, and the penetration of the brazing material 10 is made uniform. However, there was a problem in that the strength and airtightness were poor.
さらに、第１の管６と第２の管７のフランジ９の接合
が面接触で行なわれているため、せん弾力に弱いという
問題点も有していた。Further, since the flanges 9 of the first pipe 6 and the second pipe 7 are joined by surface contact, there is a problem that the elastic force is weak.
さらに、第２の管７の端部を押し広げてフランジ９を
加工するためフランジ９の外周部に割れが生じてロー付
けの信頼性が低下する可能性もあるという問題点を有し
ていた。Further, since the end portion of the second pipe 7 is expanded to process the flange 9, there is a problem that the outer peripheral portion of the flange 9 may be cracked and the reliability of brazing may be reduced. .
本発明は上記問題点に鑑み、製作工数が少なく、管の
変形を防止でき、薄肉の管材を利用でき、接合位置決め

Forming a hole slightly larger than the outer diameter of the end of the first pipe, and leaving the first pipe near the end of the second pipe leaving an insertion allowance for inserting into the hole formed in the first pipe. A flange having a curved surface along the outer surface of the pipe is integrally formed, the end of the second pipe is formed in the hole formed in the first pipe, and the curved surface of the flange is the outer surface of the first pipe. Until the outer surface of the first tube and the curved surface of the flange are in contact with each other as a joint surface.
