Claims

[Scope of utility model registration request]

A first flange is fixed to the outer circumferential surface of the end of the first pipe with a part protruding beyond the edge of the first pipe, and the first flange is fixed to the outer circumferential surface of the end of the first pipe, and the opposite side of the first flange to the first pipe is A mortar-shaped inclined surface is formed on the inner circumferential edge of the opening, a second flange is fixed to the outer circumferential surface of the end of the second pipe, and a refractory material is wound with a thin plate, and the second flange is connected to the second flange. The first flange and the second flange are aligned with each other while a closed annular sealing material having an inner diameter that can be freely fitted onto the end of the second protruding pipe is aligned with the mortar-shaped inclined surface. However, in a pipe connection using a flange, in which both the first and second pipes are joined in an air-tight and liquid-tight state by joining both flanges with bolts and nuts, the above-mentioned The outer diameter of the end of the second pipe is formed to be slightly smaller than the inner diameter of the first flange or the first pipe to which the first flange is fixed to the outer circumferential surface of the end. When the two flanges are joined, the end of the second pipe enters the cylindrical part located deeper than the inclined surface on the inner peripheral surface of the first flange, or the inside of the first pipe. A pipe connection using a flange that is characterized by its flexibility.
