304 stainless steel pipes have a long service life. From the application status of stainless steel pipes overseas, the service life of 304 stainless steel pipes can reach up to 100 years, or even 70 years, similar to that of housing construction.
Of course, the prerequisite is that the quality of the 304 stainless steel pipe you buy cannot be too poor. The advantage of 304 stainless steel pipe is its corrosion resistance. If the purchased stainless steel pipe is of good quality and can be properly maintained and cleaned during use, it can effectively extend the service life of 304 stainless steel pipe.
The factors that affect the service life of 304 stainless steel pipes generally include the following:

1. Harsh usage environment;
   304 stainless steel pipes themselves have the ability to resist atmospheric oxidation, as well as the ability to corrode in media containing acids, alkalis, and salts. However, its corrosion resistance varies depending on the chemical composition, additive state, service conditions, and type of environmental medium of the steel itself.
   In a dry and clean atmosphere, it has excellent rust resistance, but when it is moved to coastal areas, it will quickly rust in sea mist containing a large amount of salt, affecting the service life of 304 stainless steel pipes.
   When users use 304 stainless steel pipes or clean 304 stainless steel pipes with corrosive chemical products in high pollution areas such as the seaside, chemical plants, brick factories, electroplating and pickling plants, water plants, sewage treatment plants, etc., it can cause rust. We hope to keep in mind.
2. Improper processing and installation;
   Some stainless steel processors may splash iron filings onto the surface of the steel pipe when cutting stainless steel pipes or iron when making products. If not cleaned in a timely manner, it can cause 304 stainless steel pipes to rust. Installing stainless steel products before painting walls or houses can also cause stainless steel products to rust.
3. Improper cleaning and maintenance
   During the cleaning process, steel wire balls or brushes should not be used to remove water stains on the surface of stainless steel pipes, as this can cause scratches on the surface of 304 stainless steel pipes. In addition, it is necessary to avoid using bleach and abrasive cleaning solutions, including detergent containing acid and alkali properties. At the end, rinse the surface of 304 stainless steel pipes with clean water.
