Zusammenfassung:	The utility model discloses a groove type monolithic flange. A groove type single-piece flange comprises an upper semi-circular-ring flange piece, a lower semi-circular-ring flange piece and a sealingrubber ring and further comprises a hollow stamping pin shaft, and the left end of a circular structure part, provided with a circular hole A correspondingly, of the upper semi-circular-ring flange piece and the lower semi-circular-ring flange piece is connected in a rotating and riveting mode through the hollow stamping pin shaft. In a non-use state, the right ends of the circular structure parts, provided with the circular holes B correspondingly, of the upper semi-circular ring flange piece and the lower semi-circular ring flange piece are movably connected through locking fixing bolts. The consumption of mounting bolts and nuts is reduced, the groove type single-piece flange is conveniently mounted, and the mounting efficiency is improved; the overall circular structure of the groovetype single-piece flange i
