The utility model relates to a novel inner tube flange manufactured for a shield machine shell. The novel inner tube flange is characterized by comprising an inner tube body and adjusting devices. The inner tube body is of a circular ring structure, and radial through holes are formed in a ring of the circular ring structure. Through holes are formed in the walls of the radial through holes and point to the center of a circle. The connected relation is as follows: the adjusting devices are detachably connected with the inner tube body through the through holes. On the basis of an original technology flange, the adjustable bolts are arranged, so that the adjustment is convenient according to welding contraction conditions. The adjustable bolts are evenly arranged so that the shell can be evenly stressed, the circular degree is guaranteed, and the problem of welding internal stress is solved.
