<P>PROBLEM TO BE SOLVED: To reduce concentration of stress caused by a temperature difference in a flange of a piping with a high temperature fluid flowing therethrough, and to prevent crack and plastic distortion from increasing gradually. <P>SOLUTION: A plurality of cut-out parts 4 recessed toward a radial-directional inside of the flange 3 is formed with a space P along a circumferential direction of the flange 3, in an outer circumferential part of the flange 3 of the piping 1, as to flange structure of the piping 1 with the high temperature gas (high temperature fluid) flowing through an inside thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT |
