A pipeline connecting structure is provided to delay the progress of corrosion and to extend the service life, and to cut off the leakage of water by forming a sealing gasket to make contact with the entire corresponding sides of each flange of pipelines to be connected with each other. A pipeline connecting structure connects a first pipeline(100) and a second pipeline(200) by equipping with a flange(110) fixed to one end of a first pipeline and a flange(210) fixed to one end of a second pipeline, inserting a sealing gasket(300) between the flange of the first pipeline and the flange of the second pipeline, and coupling the outer parts of the flanges mutually using a coupler(400) and compressing the sealing gasket, wherein a pressure projection(P) is projected in the shape of a ring on the location equivalent to the inside of the coupler among at least one or more corresponding sides of the flange of the first pipeline and the flange of the second pipeline, and two sides of the sealing gasket are formed to make contact with each other all over the corresponding sides(111,211) of the flange of the first pipeline and the flange of the second pipeline, and a setting groove(S), where the pressure projection is placed, is formed on the corresponding side to the pressure projection.
