316 stainless steel pipe maintenance
The use of 316 stainless steel pipes has become more widespread with economic development. People are closely related to stainless steel pipes in daily life. However, many people do not have a good understanding of the performance of stainless steel pipes, and there are fewer known about the maintenance of stainless steel pipes. Many people think that the stainless steel pipe never rusts. In fact, the stainless steel pipe has good corrosion resistance because a purified film forms on the surface. In nature, it exists in the form of a more stable oxide. In other words, though the degree of oxidation differs depending on the conditions of use, stainless steel pipes are eventually oxidized. This phenomenon is usually called corrosion.
Electrochemical reaction or chemical reaction occurs on the metal surface exposed to the corrosive environment and is uniformly corroded. Among the 316 stainless steel pipe surface where the corrosion resistance is weak among the purified films, pitting reaction is formed due to the self-excitation reaction and a small hole is generated. With the close proximity of aerobic ions, a strong corrosive solution is formed, accelerating the speed of the corrosion reaction. There is also an intergranular corrosion cracking inside the stainless steel tube, all of which damages the purified membrane on the surface of the 316 stainless steel tube.
Therefore, the surface of the 316 stainless steel pipe must be regularly cleaned and maintained to maintain its surface and extend its service life. When cleaning the surface of 316 stainless steel pipe, care must be taken not to scratch the surface, and to avoid the use of bleaching components and abrasive cleaning liquids, steel wire balls. To remove the washing liquid from the grinding tools, etc., rinse the surface with water after washing.
316 stainless steel pipe maintenance method
1, the surface of stainless steel pipe dust and easy to remove the dirt can be used soap weak detergent to wash, adhesive composition, use alcohol or organic solvents (ether, benzene) scrub.
2. The grease on the surface of stainless steel pipe is contaminated with oil lubricating oil. After wiping it with a soft cloth, wash it with neutral detergent or ammonia solution or with special detergent.
3. The bleaching agent and various acids adhere to the surface of the stainless steel pipe. Rinse immediately with water, then dip in ammonia solution or neutral carbonated soda solution, and wash with neutral detergent or warm water.
4, the rainbow surface of the stainless steel tube, is caused by excessive use of detergent or oil, wash with warm water detergent can be washed.
5, stainless steel pipe surface dirt caused by rust, can be washed with 10% nitric acid or grinding detergent, can also be washed with specialized washing drugs.
As long as we use the right maintenance method, we can extend the service life of stainless steel tubes.
