Bright heat treatment device of steel pipe

The utility model relates to a bright heat treatment device of steel pipe. Bright heat treatment device of steel pipe includes as the vent pipe in thermal treatment place, still includes atmoseal part, preheater, heating furnace and cooler bin, vent pipe passes in proper order preheater, heating furnace and cooler bin, the atmoseal part has two, sets up respectively vent pipe's head and the tail both ends, still include ammonia decomposition device, ammonia decomposition device decompose the hydrogen that obtains pass through gas transmission pipeline with the vent pipe intercommunication. The utility model discloses whole journey at thermal treatment all adopts hydrogen as protective gas and reducing gas for the problem that conventional thermal treatment can make steel pipe emergence oxidation with the oxygen contact, has not been solved at ann in-process to the steel pipe, thus the process of making the utility model discloses the oxidation reaction does not take place for the steel pipe of handling, and the annealing back directly obtains bright steel pipe, has removed processes such as pickling polishing from.
