The invention discloses a corrugated pipe. The corrugated pipe comprises a corrugated pipe body, outer wall protrusion wave crests and outer wall groove wave troughs are formed in the outer wall circumference of the corrugated pipe body, and the circumferences formed by the way that the outer wall protrusion wave crests and the outer wall groove wave troughs are closed and the radial cross section circumference of the corrugated pipe body are concentric. Corresponding inner wall protrusion wave crests and inner wall groove wave troughs are formed in the inner wall of the corrugated pipe body along the outer wall protrusion wave crests and the outer wall groove wave troughs, and the cross section shape of the inner wall protrusion wave crests and the cross section shape of the inner wall groove wave troughs are isosceles trapezoids. A metal wire which extends in a spiral winding mode in the axial direction of the corrugated pipe body is arranged in the corrugated pipe body. Due to the fact that the metal wire extends in the spiral winding mode in the axial direction of the corrugated pipe body, the axial tension force of the pipe body is increased, the brittleness of the pipe body is lowered, and the service life of the pipe body is prolonged. The cross section shape of the inner wall protrusion wave crests and the cross section shape of the inner wall groove wave troughs are the isosceles trapezoids, so that the corrugated pipe has higher deformation sensitivity, when the corrugated pipe is impacted by external force fiercely, deformation can happen more quickly, and therefore internal cables can be protected from being damaged.
