Description

Technical Field

[0001] The utility model relates to the technical field of pickling, in particular to a seamless pipe pickling tank. Background Art

[0002] A seamless pipe is a long steel strip with a hollow cross-section and no seams around it. Oxide scale and rust will be produced on the surface of the seamless pipe during production. In order to improve the appearance and corrosion resistance of the seamless pipe, the seamless pipe needs to be pickled, and the surface oxide scale and rust are removed using an acid solution. For example, a stainless seamless pipe pickling tank with a prior art publication number of CN210438845U rinses the pickled seamless pipe in the pickling tank through a high-pressure water spray head, and then blows the pickled seamless pipe in the pickling tank dry through an air spray head, thereby improving the pickling quality of the seamless pipe after pickling.
