る、フランジを用いた管接続部。 A plurality of through holes formed in a first flange fixed to the outer peripheral surface of the end of the first pipe, and a plurality of through holes formed in a second flange fixed to the outer peripheral surface of the end of the second pipe. By screwing the inserted bolt and nut together and tightening them further, both the first and second flanges are joined,
A closed annular groove formed on the side surface of the first flange and on the surface facing the second flange so as to surround the entire circumference of the first pipe to provide airtightness between the opposing surfaces of both flanges. In a pipe connection part using a flange, which is held by a sealing material fitted to the flange, the outer diameter of the sealing material is held between at least the first and second flanges, The outer peripheral surface of the sealing material is sized to be in close contact with the inner surface near the outer periphery of the groove, and the inner diameter of the sealing material is set in a state where it is held between the first and second flanges.
A pipe connection part using a flange, characterized in that the size is such that a gap is formed between the inner circumference of the sealing material and the inner side surface of the groove.
