Zusammenfassung:	PURPOSE: A blow-branch pipe is provided to reduce operation costs for a furnace such as a blast furnace in which the blow-branch pipe is used, and to save energy. CONSTITUTION: A blowpipe includes an articulated expansion controller, a nozzle elbow, and a nozzle tip(1). One end of the articulated expansion controller is connected to the nozzle elbow, and the other is connected to a hot-air main pipe. At least one insulating material is arranged between a metal external structure and the fire-proof lining which form at least one of the articulated expansion controller, the nozzle elbow, and the nozzle tip. The insulating material comprises a high heat-resistant insulation inserted into a cladding material. The cladding material is melt when the blow-branch pipe is operated. The cladding material is a plastic foil and includes an inorganic siliceous material.
