The invention provides a novel spiral pipe production line and belongs to the field of production of spiral pipes. The production line comprises a decoiling device, a shovel head device, a rough leveling device, a fast butt joint device, a fine leveling device, an edge milling device, a traction device, a centering device, a cutting device and a rear axle carrier roller. A molding device comprises a bottom plate, a molding frame, a first roller beam, a second roller beam, a third roller beam, a fourth roller beam, a fifth roller beam, a sixth roller beam, a seventh roller beam and a welding pad roller. A work area used for making steel pipes is reserved in the center of the molding frame. The seven roller beams are arranged in the work area of the molding frame. An included angle is formed between every two roller beams, and the roller beams are spirally arranged. An automatic roller beam vertical sliding device and an automatic roller beam horizontal moving device are further arranged on the bottom plate. The automatic roller beam vertical sliding device is connected with the roller beam right opposite to the welding pad roller. The automatic roller beam horizontal moving device is connected with the roller beam located on the center horizontal plane of the work area. According to the novel spiral pipe production line, the structure of the production line is greatly adjusted, arrangement of the devices is more reasonable, and the yield is higher.
