<p>PROBLEM TO BE SOLVED: To provide a connecting structure applicable even to a thin stainless steel pipe having a large diameter by providing a bolt for fixing the flange of a joint body to the flange of a nipping part. SOLUTION: To connecting a thin stainless steel pipe 1, joint body 2, a nipping part 3, a nipping ring 4 and a gasket packing 5, the nipping part 3 from which a packing 10 is removed is fitted onto the stainless steel pipe 1 to form a bulge part 8 at the end of the thin stainless steel pipe 1. Thereafter, the packing 10 is inserted and fitted thereto, and the nipping ring 4 is further fitted to the fitting recessed part 34 of the nipping part 3. Thereafter, the flange 26 of the joint body 2 is connected to the flange 19 of the nipping part 3. At this time, the gasket packing 5 is put between the connecting surface 27 of the flange 26 of the joint body 2 and the connecting surface 39 of the flange 19 of the nipping part 3 and between the flange 26 and the nipping ring 4, and a bolt is inserted to the mounting hole 28 of the flange 26 of the joint body 2 and the mounting hole 31 of the flange 19 of the nipping part 3, and a nut 31 is fastened thereto to fix the joint body 2.</p> |
