<P>PROBLEM TO BE SOLVED: To provide a new pipe structure with a flange, in which a flange joint is fixed to a pipe body with sufficient fixing strength by simple work, and to provide a pipeline structure in which the pipe structure with the flange is connected to another pipe body. <P>SOLUTION: A flange joint 3 in the inner peripheral face 313 of which a projected or recessed second engaging part 314 is provided, is externally fitted to a pipe body 2 in the outer peripheral face 22 of which a projected or recessed first engaging part 21 is provided. The flange joint 3 is fixed to the pipe body 2 with a reinforced material layer 5 which is formed by overlaying a fiber-reinforced resin in an area from an outer peripheral face of a short pipe 31 of the flange joint 3 to the outer peripheral face 22 of the pipe body 2 while filling an annular level difference formed between the pipe body 2 and the short pipe 31 of the flange joint 3, and curing the resin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
