The utility model discloses a corrugated pipe for blast furnace cooling wall pipe penetration. The corrugated pipe comprises a corrugated pipe body, wherein the corrugated pipe body is a hollow pipe; the corrugated pipe is characterized in that the corrugated pipe body comprises a wide corrugated section and a narrow corrugated section; the wide corrugated section and the narrow corrugated section are arranged at an interval in a cycle combined mode; the wide corrugated section is a cylindrical hollow pipe; the narrow corrugated section is recessed inwards radially relative to the wide corrugated section; the width of the wide corrugated section is larger than that of the narrow corrugated section. The difference between the width of the wide corrugated section and the width of the narrow corrugated section is fully utilized, and a blind area can be prevented from being formed in the corrugated section. Meanwhile, dirt accumulated in the corrugated section is avoided, so that local overheating or local boiling is unlikely to be caused, a cooling effect of the corrugated pipe can be effectively improved, and the service life of the corrugated pipe is prolonged. Compared with a conventional corrugated pipe, the corrugated pipe has the advantages that the thickness of a pipe wall can be increased through the corrugated sections, so that the service life of the corrugated pipe can be further prolonged.
