Further, in step S1, the selected pipe diameter ranges from 89mm to 219mm, and the pipe diameter specifications include, but are not limited to, 114mm, 140mm, 168mm, and 219 mm.
Further, in step S1, the cutting of the pipeline is completed when the pipeline is blanked.
Further, in step S2, steel marks are stamped on the outer wall of the pipe according to the processing technology of the pipe, so as to distinguish the pipe in the subsequent processing process.
Further, in the step S3, the pipeline after being cut and stamped is assembled with the flange on the assembling machine, and spot welding is performed to ensure that the flange is connected with the pipeline.
Further, in step S4, the welding robot is controlled to weld the inner and outer side welds of the pipeline, and welding process parameters are preset for the robot.
Further, in the step S4, after the pipeline requiring no pipe bending is finished, the straight pipe is repaired and polished, and is subjected to surface treatment and inspection to complete the processing of the straight pipe in step S41.
Further, in step S5, the pipe fittings to be bent are put into the pipe bending station together with the flange, and the pipe is bent by the pipe bending machine.

The working principle is as follows: in step S1, a designated pipe is selected according to the production plan, and the pipe is blanked, and the pipe is cut during blanking, so as to facilitate subsequent processing. In step S2, steel stamping is performed on the pipeline, so as to facilitate the subsequent distinguishing of the pipeline; meanwhile, the end face of the pipeline is polished, so that subsequent butt joint with the flange is facilitated. In step S3, the flange and the pipe are assembled by an assembling machine and fixed by spot welding. In step S4, the robot is controlled to weld the inner and outer welds of the pipe and the flange, and the machining parameters of the robot are set in advance.
