Stainless steel pipe railings mainly refer to railings made of stainless steel pipes. Stainless steel railings are corrosion resistant and have simple lines and aesthetics. Therefore, it has gradually become an essential railing for decoration.

Stainless steel railings can also rust if they are not well protected. The stainless steel railing is a layer of extremely thin and strong and stable chromium-rich oxide film (protective film) formed on the Surface to prevent the oxygen atoms from continuing to infiltrate and continue to oxidize, thereby obtaining the ability to resist rust. Once for some reason, the film is continually destroyed, oxygen atoms in the air or liquid will continue to infiltrate or iron atoms in the metal will continue to separate out, forming loose iron oxide, and the metal Surface will be continuously rusted. There are many forms of such Surface film damage, and the following are common in daily life:
1. The Surface of the stainless steel railing is filled with dust or other metal particles containing other metal elements. In the humid air, the condensed water between the attached material and the stainless steel is connected into a micro battery, which triggers the electrochemical. In response, the protective film is destroyed, which is called electrochemical corrosion.
2. The Surface of the stainless steel railing adheres to the organic juice (such as melon, noodle soup, glutinous rice, etc.), and in the case of water and oxygen, constitutes an organic acid, and the organic acid corrodes the metal Surface for a long time.
3. The Surface of the stainless steel railing adheres to acid, alkali and salt substances (such as alkali water and lime water splashing on the wall), causing local corrosion.
4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), in the case of condensed water, sulfuric acid, nitric acid, acetic acid liquid point is formed, causing chemical corrosion.
Identification of the advantages and disadvantages of stainless steel railings
Method one is observed through the eyes. The quality of stainless steel railings can be distinguished by luminosity and color to see if the color is even and bright.
Method two, through the touch of the hand. Look at the Surface of the stainless steel railing by hand to see if the stainless steel railing is smooth and smooth. The other important aspect is to look at the thickness of the stainless steel railing wall. Press the Surface of the pipe to see if there is any indentation to see the thickness.
Method 3: By listening to the sound of the stainless steel railing, the thickness of the stainless steel railing can be judged by the sound quality, and the sound quality of the thick and thick steel tube is thicker than the sound quality.
