The present invention relates to a flange assembly for connecting ducts, wherein a hollow insertion member of which one side is inserted and coupled to the inside of a duct is made of a synthetic resin material and a flange member integrally formed on the other side of the insertion member is made of a metal material and the insertion member and the flange member are integrally molded through an injection molding method in order to reduce time and manufacturing costs required for processing, having excellent chemical resistance to be semi-permanently used. To this end, according to the present invention, the flange assembly for connecting ducts (100) comprises: the cylindrical hollow insertion member (110) of which one side is inserted into and coupled to the inside of the duct (1) and made of the synthetic resin material; and the metallic flange member (120) integrally coupled to the outer circumferential surface of the other side of the insertion member (110) and protruding to have a larger diameter than the outer diameter of the duct (1). |
