[0022] When the pipe thawing device of this embodiment is in use, the first thawing pipe 1 is fixedly connected between two adjacent frozen pipes 3, and each frozen pipe 3 is also sleeved with a second thawing pipe 2. When the weather is extremely cold, after the two frozen pipes 3 are frozen and blocked, the first valve 5 on the exhaust and drainage port is fully opened first, and then the first valve 5 on the steam pipe 4 is slowly opened to ensure that the pressure inside and outside the pipe is balanced, and the external hot steam enters the two frozen pipes 3 through the steam pipe 4, the steam inlet and the first thawing pipe 1, and thaws the medium in the two frozen pipes 3.
