PURPOSE: A weldlesss band-type pipe joint using a flaring process is provided to improve air-tightness by inserting a gasket extended in an inverse V-shape into pipes. CONSTITUTION: A weldlesss band-type pipe joint using a flaring process comprises pipes(110), first and second gaskets(120,130), a band(140), and multiple ring joints(150). Extended parts(111) are formed by extending the ends of the pipes through a flaring process. The first and second gaskets are coupled to the inner and outer surfaces of the extended parts of the pipes. A bolt(143) is coupled to one end of the band, and a rotary nut(147) is coupled to the other end. The ring joints are welded to the inner surface of the band at uniform intervals. The extended parts of the pipes are inserted into the insertion grooves of the ring joints.
