A rapid pipe freezing method including a process of wrapping the pipe with a cooling coil along the outer circumference surface of the pipe rapidly is disclosed. The method includes bending the cooling coil not to be blocked by itself so that a refrigerant flow through the inside thereof and arranging the cooling coil to form a freezing area, fixing the cooling coil to fix the cooling coil on one surface of the cover sheet such that at least one part of the freezing area may be overlapped with the cover sheet, installing the cover sheet wrapping the outer circumference surface of the pipe with the cover sheet such that the cooling coil of the freezing area may face the outer circumference surface of the pipe, and flowing a refrigerant by connecting a refrigerant cooling device to the one end of the cooling coil and the other end of the same and flowing a refrigerant through the inside of the cooling coil to freeze the inside of the pipe where the freezing area is overlapped. |
