As a common pipe material, stainless steel pipe has important applications in industrial production and life. In many cases, the inner wall of stainless steel pipes needs to be polished to increase its surface finish and improve its service life. Among them, electrolytic polishing technology is a commonly used and effective polishing method. Let's take a closer look at how to electrolytically polish the inner wall of stainless steel pipes.
1. Overview of the process of electrolytic polishing of stainless steel pipes
Electrolytic polishing refers to dissolving a layer of material on the surface of the pipe through electrochemical reaction to achieve the purpose of smoothness and cleanliness. Specifically, the stainless steel pipe that has been pretreated (such as mechanical grinding, pickling, etc.) is used as an anode and placed in an electrolytic tank. The electrolyte is used as the medium and electrolysis is performed under certain conditions. Through anode dissolution, electrolysis induction accumulation, The anode is weakened or detached, etc., causing the inner surface of the tube to be polished.
2. Operating steps for electrolytic polishing of stainless steel pipes
(1) First, the stainless steel pipe to be polished is pretreated to make the inner wall surface of the pipe flat and smooth to facilitate subsequent electrolytic polishing operations.
(2) Place the pretreated pipe in the electrolytic tank to make it an anode, and install the electrolyte circulation system, electrolyte heating system, etc.
(3) Turn on the heating, electrolyte circulation and other equipment of the electrolytic tank, set appropriate current density, electrolyte temperature, electrolysis time and other parameters in the electrolyte. After the temperature, current, and liquid level are stable, start electrolytic polishing. .
(4) After polishing, close the electrolytic tank, electrolyte circulation and other equipment, take the tube out of the electrolytic tank, and perform cleaning, drying, quality inspection and other operations.
