Claims

[Scope of Claim for Utility Model Registration] A connecting flange is fitted onto the outer periphery of the end of a pressure-feeding pipe, and this connecting flange is integrally fixed to the pressure-feeding pipe by welding, and the connecting flanges are connected with a joint to form a pressure-feeding pipe. A connection structure for pressure-feeding pipes configured to connect, the connecting flange having a first inner circumferential surface equal to the outer diameter of the pressure-feeding pipe and a second inner circumferential surface equal to the inner diameter of the pressure-feeding pipe, on the inner periphery of the connection flange.
By connecting the inner circumferential surface of the connecting flange to the inner peripheral surface of the pressure-feeding pipe, the end face of the connecting flange is made to protrude a predetermined length from the end face of the pressure-feeding pipe, and the connecting flange is fitted to the outer periphery of the end of the pressure-feeding pipe. A connecting structure for pressure-feeding pipes, characterized in that a reinforcing ring is fitted around the outer periphery of the pressure-feeding pipes.
