り、そのため製品価値が損なわれるという欠点が
ある。 However, O-rings, Teflon seals, gaskets, etc. have restrictions on how they can be used, their dimensions are standardized, and materials are limited to rubber, Teflon, etc., so even if other parts are made smaller and lighter, this joint However, they inevitably become larger and heavier, which has the disadvantage of reducing product value.

る。以下本考案を図面に基づき説明する。 The present invention has a structure in which the outer diameter of the joint portion is approximately the same as the outer diameter of the steel pipe, and can sufficiently withstand internal and external pressures of about 15 kg/cm 2 without reducing the inner diameter. The present invention will be explained below based on the drawings.

のである。 A sharp clamping part 4 is formed at the root of the threaded part 3 of one of the two small diameter pipes 1 and 2 to be joined, and a sharp clamped part 4 is formed at the tip of the threaded part 5 of the other small diameter pipe 2. An annular gasket 7 is arranged between the two clamping parts 4 and 6, and by tightening the threaded parts 3 and 5 of both pipes, both sides 8 and 9 in the width direction of the gasket 7 are formed. Both the clamping parts 4 and 6 are designed to bite into.

径管の外径とほぼ同じであるため小型軽量化を実
現することができる。 As described above, the present invention has excellent airtightness because the clamping parts 4 and 6 bite into both sides 8 and 9 in the width direction of the gasket 7, and the outer diameter is almost the same as the outer diameter of the small diameter pipe to which it is connected. Since they are the same, they can be made smaller and lighter.
またガスケツトとして無酸素銅を使用すれば耐
圧だけでなく耐熱性にも優れ、従つて炉内観察用

する。 Furthermore, if oxygen-free copper is used as the gasket, it will have excellent not only pressure resistance but also heat resistance, and is therefore suitable for use as a protective tube for a fiberscope for observing the inside of a furnace.
