What are the polishing treatment methods for large-diameter seamless steel pipes?

Large-caliber seamless steel pipes pay more attention to the surface layer in the production and manufacturing. The surface layer should be polished to remove the barbs on the surface layer. It is very prone to scratches during the entire transportation process. What are the polishing treatment methods for large-diameter seamless steel pipes?

1. Dry milling and metal wire drawing

Polished metal wire drawing does not require investment in production equipment, the actual operation is simple and convenient, and the scope of application is wide. Generally speaking, stainless steel pipes can show excellent actual results after one polishing and wire drawing process.

2. Oil milling and metal wire drawing

The stainless steel pipe undergoes scraping and metal wire drawing production and processing, and is mainly used for the decoration design of elevator cars and some electrical products. After the metal wire drawing, the actual effect is very beautiful, and the decorative design effect is very good.

3.8K resolution

8K production cost is low. In the whole process of the continuous development trend, the 8K production and processing technology of sodium cyanide and iron oxide red is very fashionable in the field at this stage. The current technology can achieve the actual effect of mirror glass after the 8K solution is carried out on the cold-rolled surface of the stainless steel pipe.

4. Titanium

The titanium key is used as a high-end architectural decoration material, which has a very beautiful practical effect of decoration design. After the solution, its corrosion resistance will be greatly improved, and it can be widely used in various applications.
