Pipe processing production line

The invention discloses a pipe processing production line which comprises an automatic pipe feeding device, an assembling and welding device, a pipe overturning device capable of overturning a pipe from the automatic pipe feeding device to the assembling and welding device, and a station crane capable of cooperating to hoist and transport the pipe on the assembling and welding device, wherein theassembling and welding device is connected with the automatic pipe feeding device through the pipe overturning device. According to the pipe processing production line, the assembling and welding device is connected with the automatic pipe feeding device through the pipe overturning device, the pipe is transferred to the pipe overturning device via the automatic pipe feeding device, and then the pipe overturning device overturns the pipe to the adjacent assembling and welding device to quickly finish the welding process of a pipe fitting and the end face of the pipe; all devices are reasonablein layout, the turnover l
