The invention provides a large-pipe-diameter circular pipe cutting production line, and belongs to the technical field of flame cutting. Comprising a plurality of lifting trolleys used for longitudinally or transversely adjusting the position of a round pipe to be cut and two cutting mechanisms used for cutting the round pipe through flames, the lifting trolleys are located on the sides, close to each other, of the two cutting mechanisms, and the cutting mechanisms and the lifting trolleys are linearly arranged; the cutting mechanism comprises a cutting main machine frame. By arranging the cutting main machine frames, the flame cutting gun head, the position adjusting assembly and the rotating assembly, the flame cutting gun head can conduct rotary cutting around a round pipe, after cutting is completed, the two cutting main machine frames are far away from each other along a straight line through the driving wheels, and the cut round pipe is lifted away from the lifting trolley. A worker does not need to pos
