The utility model relates to a pipeline connecting flange which comprises two flange plates in butt joint, a sealing gasket and a connecting screw, corresponding connecting holes are formed in the two flange plates, and the connecting screw penetrates through the connecting holes to fix the two flange plates. According to the improvement, the two flange plates are a through flange plate and a blind flange plate respectively, at least two through holes are formed in the through flange plate, blind holes corresponding to the through holes in the through flange plate are formed in the blind flange plate, the positioning screws penetrate through the through holes, and the front ends of the positioning screws are located in the blind holes. According to the connecting flange of the structure, when the sealing gasket is replaced, the positioning screw can always keep the concentricity of the two flanges unchanged, under the cooperation of the positioning screw and the connecting screw, the sealing gasket can be rap
