A one-time forming equipment for polyethylene corrugated pipes and a corrugated pipe thereof comprise a support, on which a turntable fixing support is installed. An annular guide rail is installed on the turntable fixing support, and a turntable is installed on the turntable fixing support, driven by a motor. An inner pipe extruder is fixed on the support, with an inner pipe feeding box arranged on the inner pipe extruder, and one end of the inner pipe extruder is connected to an inner pipe mold. The corrugated pipe produced by the equipment of the invention is formed in one step from polyethylene material, so that the inner wall of the pipe is smooth with a relatively thin wall thickness. The ring stiffness of the pipe is equivalent to that of existing polyethylene pipes, saving materials. It has high production efficiency, reduced production cost, and waste pipes are easy to recycle. The production efficiency of the corrugated pipe is more than 50% higher than that of existing polyethylene drainage pipes, the cost is 20%–30% lower, and waste pipes can be 100% recycled.
