Quenching equipment for pipes

The utility model provides quenching equipment for pipes. The quenching equipment comprises a cold air gun and a cooling water tank, the cold air gun is arranged on the front end side of the pipe pulled by external force to move; the cooling water tank is arranged on the rear end side, pulled by external force to move, of the pipe, and the cooling water tank and the cold air gun are arranged at intervals. Wherein the cold air gun is used for providing cold air to carry out blowing coating and cooling on the pipe, and the cooling water tank is used for carrying out quenching operation on the pipe arranged in the cooling water tank in a penetrating mode. Before quenching operation is carried out, blowing and cooling operation is carried out on the pipe through the cold air gun, it is ensured that after the temperature of the pipe is reduced to the required first temperature, the input pipe subjected to preliminary cooling is further cooled in a cooling water immersion mode through the cooling water tank, and th
