Disclosed in the present invention is a method for rapidly freezing a pipe, which includes a process of rapidly surrounding the outer circumferential surface of a pipe with a cooling coil. The disclosed method for rapidly freezing a pipe comprises: a cooling coil aligning step for forming a freezing area from a cooling coil, which is extended to allow a refrigerant to flow therein, by aligning the cooling coil to not be closed; a cooling coil fixating step for aligning and fixating the cooling coil at one side surface of a cover sheet in order to make at least one part of the freezing area to overlap with the cover sheet; a cover sheet installing step for covering the outer circumferential surface of the pipe with the cover sheet so that the cooling coil of the freezing area can face the outer circumferential surface of the pipe; and a refrigerant flowing step for connecting a refrigerant cooling device at one side end and the other side end of the cooling coil and freezing the inside of the pipe that overlaps with the freezing area by making the refrigerant flow inside the cooling coil. |
