用いた管接続部。 A first flange fixed to the outer peripheral surface of the end of the first pipe and a second flange fixed to the outer peripheral surface of the end of the second pipe are aligned with each other and joined by bolts and nuts. The first pipe is sealed by a closed annular sealing material, which is sandwiched between the first and second flanges and is made of a thin plate of refractory material wound and has an inner diameter that is the same as or slightly larger than the outer diameter of the second pipe. , in a pipe connection using a flange that maintains airtightness and liquidtightness between the second two pipes, the end of the second pipe is moved slightly in the axial direction of the pipes relative to the second flange. The above-mentioned sealing material is fitted onto the protruding end, and is fixed to the end of the first pipe with a portion thereof protruding beyond the edge of the first pipe. A mortar-shaped inclined surface that is aligned with the sealing material is formed in the inner circumferential opening, and the end of the portion of the sealing material that is located outside the overlapping portion of the thin plates is formed on this inclined surface or the second flange. The sealing material is provided so as to face outward from the point of contact with the side surface of the closed ring, and the angle of this inclined surface with respect to the plane orthogonal to the central axis of each tube is 46 to 56.
The overlapping portion of the sealing material is brought into contact with this inclined surface at an angle of 47 to 55 degrees, or the overlapping portion of the sealing material is brought into contact with the side surface of the second flange at an angle of 47 to 55 degrees. Pipe connections using flanges.
