In the production of seamless steel tubes today, the perforation process is widely used and very economical. In the production of seamless steel tubes, the perforation process is more reasonable, and the perforation process is automated. Common perforators include cone-roll perforators and drum-roll perforators.

The role of perforation technology in modern steel pipe production?
In the production of seamless steel tubes, the function of the perforation process is to perforate the solid tube blank into a hollow capillary tube. The entire production process generally includes perforation, tube rolling, and sizing and reducing processes. Perforation is the first process of metal deformation. The pierced tube is thicker, shorter in length, and has poorer inner and outer surfaces, so it is called a capillary. If there are some defects in the capillary, it is difficult to eliminate or alleviate them after the subsequent process. Therefore, the perforation process plays an important role in the production of seamless steel tubes.

How to carry out the pickling process for seamless steel tube?
In the rolling process of seamless steel tubes, especially precision seamless steel tubes, the pickling process is very important to remove the oxide scale and rust on the surface. So how does pickling of seamless steel tube work?

seamless steel tube

The method of removing scale and rust on the surface of steel with an acid solution is called pickling. Iron oxides such as scale and rust (Fe3O4, Fe2O3, FeO, etc.) chemically react with the acid solution to form salts, which are dissolved in the acid solution and removed. Pickling acids include sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, and mixed acids.

Common media for pickling of precision seamless steel tubes:
Sulfuric acid, nitric acid, phosphoric acid, and hydrofluoric acid. When pickling, be sure to add a pickling inhibitor to prevent the acid from corroding the metal.
