[0002] Metal pipes play a vital role in the industrial production process. Since metals are easily corroded in a humid environment, in order to protect metal pipes from corrosion, they need to be passivated before leaving the factory. The traditional passivation methods for metal pipes are divided into electrical passivation and chemical passivation.

[0003] For example, the utility model patent with announcement number: CN206768232U discloses a metal pipe pickling device, which can be rotated and adjusted to improve adaptability; it is easy to move and has strong reliability in use; it includes a pickling basin, a working chamber is arranged inside the pickling basin, a take-in and put-out port is arranged at the top of the pickling basin, and a liquid outlet pipe is arranged on the side wall of the pickling basin; it also includes a support plate, a rotating shaft, four sets of legs and four sets of rollers, the top of the support plate is provided with a placement groove, and ball bearings are arranged in the placement groove; it also includes a left mixing barrel, a left connecting pipe and a left motor, the bottom output end of the left motor is provided with a left transmission shaft, and the left transmission shaft is provided with a left stirring blade; it also includes a right mixing barrel, a right connecting pipe and a right motor, the bottom output end of the right motor is provided with a right transmission shaft, and the right transmission shaft is provided with a right stirring blade.
