凍結防止用保温構造。 A belt-shaped electric heater for freezing prevention is wrapped around the piping, and heat is kept in a heat-retaining tube made of hard urethane foam whose inner diameter is slightly larger than the outside diameter of the belt-shaped electric heater for freezing prevention wrapped around the piping. In addition, by injecting hard urethane foam foamed on-site into the end portion of this heat-insulating cylinder, a structure is created that blocks the free flow of the heat-insulating internal air and outside air. Heat retention structure.
