Process Characteristics Of High Quality Stainless Steel EP (Electro Polishing) Tube/Pipe

The technology of using a metal workpiece as an anode and electrolyzing in a suitable electrolyte to selectively remove its rough surface and improve the surface finish is also called electrolytic polishing.

Electro polishing can increase the corrosion resistance of stainless steel, reduce the resistance of electrical contact points, prepare metallographic grinding slices, improve the reflective performance of lighting fixtures, improve the accuracy of various measuring tools, beautify metal daily necessities and handicrafts, etc. It is suitable for polishing steel, aluminum, copper, nickel, and various alloys.

The following are the main features and advantages of electrolytic polishing:

1. Bright surface: electro polishing can make the surface of the steel pipe achieve a bright, smooth, clean effect, showing a bright mirror luster.

2. Improve corrosion resistance: through electropolishing treatment, a uniform layer of chromium oxide film can be formed on the surface of the steel pipe, which can effectively improve the corrosion resistance of the steel pipe and make it more durable.

3. The reasonable surface treatment method: electrolytic polishing is an efficient, environmentally friendly, and controllable surface treatment method. It can adjust the corresponding process parameters according to different needs and materials to achieve a reasonable surface treatment effect.

4. High equipment cost: Compared with traditional surface treatment methods such as mechanical polishing and chemical polishing, electrolytic polishing has higher equipment and process costs, requiring more investment and technical support.

5. High requirements for surface quality: Electro polishing has high requirements for the quality of steel pipe surfaces. If there are serious scratching, holes, slag inclusion, precipitation, and other problems on the surface of the steel pipe, it may affect the success rate of electro-polishing.

6. Can control the thickness of chromium oxide film: by controlling the voltage, current, acid composition, and polishing time in the process of electrolytic polishing parameters, can control the thickness of chromium oxide film, to achieve different corrosion resistance and brightness requirements of surface treatment.

In short, EP electrolytic polishing is an advanced surface treatment technology that can make the surface of stainless steel pipes more beautiful, smooth, and clean, and improve its corrosion resistance. Although the production cost is relatively high, EP electrolytic polishing is a very surface treatment method for steel pipe products that require high quality and high durability.
