The invention relates to a paint removing method used for a baking-typed coating oil pipe and special equipment thereof, which comprises the steps as follows: used coating oil pipe to be disposed is wholly pushed into a carbonization heating furnace system and heated to 450-470 DEG C with the heating time of 100-140 minutes; the carbonization heating furnace system stops running subsequently; after the used coating oil pipe is cooled, the disposed used coating oil pipe is moved out to carry out the restoration disposal; the carbonization heating furnace system comprises a system base, a trolley device and a sealing carbonization heating furnace; the system base is arranged below the sealing carbonization heating furnace and the trolley device; the system base is provided with a track on which the trolley device slides; the track extends below the sealing carbonization heating furnace; the length of the internal chamber of the sealing carbonation heating furnace is slightly more than the length of the disposed used coating oil pipe. The method and the equipment of the invention can cleanly carbonize the coating on the surface of the coating oil pipe without affecting the mechanical performance of the oil pipe, thus leading the used coating to be used repeatedly and greatly saving the cost; furthermore, the disposal time is greatly shortened.
