PROBLEM TO BE SOLVED: To provide a heat insulating pipe cover superior in product quality, handling property and workability, applicable to an already constructed pipeline and capable of maintaining a function as a heat retaining material under any bad conditions. SOLUTION: A pipe cover body 8 molded of a glass fiber mat is cut at its center to be split into two parts and then an aluminum foil 10 is adhered thereto while encircling one center cut face as a starting point. Thus, it can be installed on the already constructed pipeline. It also has waterproof property with the aluminum foil 10. Preferably, the pipe cover body 8, when molded, uses a proper amount of water repellent coating agent mixed into a binder. It is therefore usable as a heat retaining material for the pipeline at an oil refinery company or a general plant site because of water repellent property with the coating agent and waterproof property with the aluminum foil 10.
