The invention relates to a tool in the technical field of steel pipe processing, in particular to a steel pipe local heating device with cooling water jackets. The steel pipe local heating device comprises a device body, and the device body is provided with a rack. Steel pipe placement tables are arranged at the two ends of the rack, and a cantilever is arranged in the middle of the rack. A base is arranged on the rack under the cantilever, a plurality of flame nozzles are arranged under the cantilever and on the base and face the position of a steel pipe, and the outlets of the flame nozzlesare arranged in a circular array. The steel pipe local heating device is characterized by also comprising one or more water jackets, the water jacket is of a circular ring structure on the whole, thesection of the water jacket is of an open box-shaped structure, and rubber sealing rings are arranged on the two sides of the opening. The water jacket is provided with a water inlet pipe and a wateroutlet pipe, and the water inlet pipe is connected with a water pump. Each rubber sealing ring is of a structure matched with the outer diameter of the steel pipe needing to be heated. Thus, when heating the local part of the steel pipe, the heating device has the advantages of strict limitation, other parts cannot be heated, and some technological requirements can be met.
