。[Claims for Utility Model Registration] (1) A first pipe and a second pipe having a smaller inner diameter than the first pipe are connected to each other by a flange formed at the connecting end of each pipe. In the connection part structure of the piping, the connecting end of the first piping has a cylindrical part inserted into the first piping from the tip, and a cylindrical part formed at the rear end of the cylindrical part. A flow regulating member consisting of a flange interposed between the pair of flange parts is disposed, and the inner surface of the cylindrical part is formed with a curved or tapered surface whose diameter gradually decreases from the tip side to the rear end side. Further, the inner diameter of the tip of the cylindrical part is made almost the same as the inner diameter of the first pipe, and the inner diameter of the rear end is made almost the same as the inner diameter of the second pipe. A piping connection structure characterized by: (2) The axial length of the cylindrical portion is greater than the length obtained by subtracting the inner diameter of the second pipe from the inner diameter of the first pipe. structure. (3) The piping connection structure according to claim 1 or 2, wherein the first piping or the second piping is a piping section formed integrally with the device.
