PURPOSE: An air supply pipe of an annealing furnace is provided to fix securely without using a separate fastening member in an installation of a combustion filter. CONSTITUTION: An air supply pipe of an annealing furnace comprises a combustion filter (100) inhaling an outside air, a transfer pipe (200), a connection pipe (120), a second joint part (210), multiple base parts, and a clamp (230). In a lower end circumference surface of the connection pipe, a first joint part is protruding and formed. The second joint part is combined with the first joint part. The base part is protruding from an upper circumference surface of the transfer pipe. The clamp is rotatable by being hinge-combined with the base part. The clamp fixes the first joint part by being adhered closely to an upper end of the transfer pipe when the transfer pipe and the combustion filter are combined. |
