とするフランジ管接続部の防食構造。 An annular plate-shaped synthetic resin foam with approximately the same diameter as the flange and cut in at least one radial direction is attached to both sides of the flange of the flange pipe connection section connected with bolts and nuts. The protruding bolt portion and nut portion are fitted into holes formed on the side surface of the foam, and the outer circumferential surface of the flange pipe connection portion including the foam has a mating flange in a shape that approximately matches this. An anti-corrosion structure for a flange pipe connection, characterized in that it is closely covered with a split-shaped anti-corrosion adhesive cover whose inner surface is coated with an adhesive, and the corresponding mating flanges are in close contact with each other.
