The invention provides a steel pipe plastic-lining production line. A support groove of an automatic plastic pipe kick-off machine is arranged corresponding to a discharge port of a plastic pipe forming device. A pipe-threading process cooling bed is arranged between the automatic plastic pipe kick-off machine and a pipe-threading machine. A first roller conveyor is connected between the pipe-threading process cooling bed and a super-audio frequency compound machine, a second roller conveyor between the super-audio frequency compound machine and a belt rolling machine, and a third roller conveyor between the belt rolling machine and a packing frame. Passivation devices are arranged on both the second roller conveyor and the third roller conveyor. The steel pipe plastic-lining production line of the invention features a high degree of automation throughout the whole process from plastic pipe production to final collection of plastic-lined steel pipes, is easy to operate, improves the production efficiency of steel-plastic pipes, and enhances operator safety.
