In the process of seamless steel pipe processing, the steel pipe with oxidation on the outer surface needs to be pickled to clean the oxides on the surface of the steel pipe and enhance the service life of the steel pipe. The current pickling method for steel pipe processing is usually to immerse the steel pipe horizontally in the pickling tank until the oxides on the surface of the steel pipe are removed. However, there may be some pickling liquid left in the pipe after pickling, which may cause the pickling liquid to drip randomly when the steel pipe is taken.

[0003] In order to solve the above technical problems, the prior art patent (CN217536176U) discloses a seamless steel pipe pickling device, including a pickling box, a sealing cover, a mounting frame, a first limit frame, an elastic clamping mechanism, a rack, a gear and an ear plate and other components.
