Stainless Steel Tube Mill: How to extend the service life of stainless steel pipes?YXH will give you a solution
People are closely related to stainless steel products in their daily lives, but many people do not know much about the performance of stainless steel, thinking that stainless steel is the same as its name. Stainless steel will never rust. In fact, the corrosion resistance of stainless steel is good because a purified film is formed on the surface. In nature, it exists in the form of a more stable oxide, but although the stainless steel has different oxidation levels according to different conditions of use, but Eventually they are oxidized. This phenomenon is usually called corrosion.
The parts with weak corrosion resistance in the purification film on the surface of stainless steel products, due to the electrochemical or chemical reaction exposed on the metal surface in the corrosive environment, thus forming pitting imagination, generating small holes, plus oxygen ions close to form a strong Corrosive solutions accelerate the rate of corrosion reactions.
In order to prolong the service life of stainless steel, the following points are summarized for the possible corrosion phenomena and measures of stainless steel:
1. Cleaning method
When cleaning the stainless steel surface, care must be taken not to scratch the surface, avoid the use of bleaching ingredients and abrasives, washing liquid, steel balls, abrasive tools, etc. In order to remove the washing liquid, rinse the surface with clean water at the end of the washing.
2. How to deal with dust
The stainless steel surface has dust and easy to remove dirt can be washed with soap and weak detergent. The binder component is scrubbed with alcohol or organic solvents (ether, benzene).
The grease on the surface of the stainless steel and the oil and lubricating oil are contaminated. After cleaning with a soft cloth, wash with a neutral detergent or ammonia solution or with a special detergent.
4. Acid corrosion
The surface of the stainless steel has bleach and various acids attached to it. Immediately rinse with water, then dip with ammonia solution or neutral carbonated soda solution, and wash with neutral detergent or warm water.
5. Rainbow pattern on the surface
The surface of the stainless steel has rainbow patterns, which is caused by excessive use of detergent or oil. It can be washed away with warm detergent in warm water.
6. Attach rust
The rust caused by the dirt on the stainless steel surface can be washed with 10% nitric acid or abrasive detergent, or with special cleaning chemicals
