Large thin-wall steel pipe production transfer system

The invention provides a large thin-wall steel pipe production transfer system, and relates to the technical field of steel pipe machining. An automatic positioning steel pipe allocation and transportation device is used for grabbing semi-finished or finished steel pipes and transferring the steel pipes to corresponding stations; the steel pipe damping and supporting device is arranged at the first station and used for temporarily supporting the semi-finished steel pipes grabbed by the automatic positioning steel pipe dispatching and transporting device, and meanwhile the damping and buffering effects are achieved. The automatic positioning steel pipe allocating and transporting device is arranged at the second station and used for supporting the finished steel pipe after the finished product machining is carried out on the semi-finished steel pipe grabbed by the automatic positioning steel pipe allocating and transporting device through the steel pipe damping and supporting device; pipelines with different d
