Rust condition of ASTM A213 TP316H stainless steel pipe

ASTM A213 TP316H stainless steel pipe is easy to rust under what circumstances? When other metals are attached to the surface of the stainless steel pipe, the probability of rusting will be relatively large, and the surface adhesion contains acids, alkalis, and salts, or when there are many harmful substances in the exhaust, the stainless steel pipe is also prone to rust. . Let's take a look at the specific introduction.

1. When other metals are attached to the surface of ASTM A213 TP316H stainless steel pipe, the probability of rusting will be relatively large. The rust caused by other metals attached to the stainless steel pipe is generally not serious. We can use a sponge or cloth, neutral detergent, toothpaste or soapy water to clean the rust on the stainless steel pipe.

2. Organic juices (such as vegetables, noodle soup, sputum, etc.) adhere to the surface of stainless steel. In the presence of water and oxygen, organic acids are formed, and organic acids will corrode the metal surface for a long time.

3. The surface of stainless steel adheres to substances containing acids, alkalis and salts (such as alkali water and lime water splashing from the decoration walls), causing local corrosion.

4. When there are many harmful substances in the exhaust gas, ASTM A213 TP316H stainless steel pipe is also easy to cause rust. For example, in factories or areas with heavy traffic on urban streets, there will be more harmful substances in the air, and the appearance of stainless steel pipes will be easily polluted. Small rust spots may appear on stainless steel pipes that have been in this condition for a long time.

If the pollution of ASTM A213 TP316H stainless steel pipe is light, you can use the previous method. If it is more serious, you can use stainless steel rust remover to scrub. If it is serious, it is recommended to consult whether it needs to be replaced.
