PURPOSE: An expansion joint pipe is provided to absorb vibration and shock, and to prevent the corrosion of the pipe caused by fluid. CONSTITUTION: Both ends of a corrugated pipe(5) are fit into a connection hole(10) in each flange(1a,1b). A first welding unit(6) is formed at both ends of the corrugated pipe, and fixes the corrugated pipe on the connection hole. A gasket(7) is fixed on the flange by a second welding unit(8). The second welding unit covers a portion of the first welding unit, and prevents the exposure of the connection hole.
