Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe pickling tanks, in particular to an environmentally friendly steel pipe pickling tank. Background Art

[0002] Oxide scale will be formed on steel pipes during the production process. Pickling can remove it and make the surface of the steel pipe cleaner. Pickling helps to improve the smoothness and flatness of the steel pipe surface and improve the appearance quality. After removing the oxide scale and impurities, the steel pipe can perform better in subsequent welding, painting and other processes, thereby improving the processing performance.

[0003] When a common steel pipe pickling tank is used for pickling of steel pipes, since the top of the pickling tank is exposed to the outside, pickling mist is easily emitted to the outside when cleaning the steel pipe, thereby polluting the environment and causing harm to the personnel. In view of this, we propose an environmentally friendly steel pipe pickling tank. Utility Model Content
