Stainless steel pipes (SS pipe) have a long service life. From the analysis of the use of stainless steel abroad, the service life of stainless steel water pipes can reach 100 years, at least 70 years, which is the same as the service life of buildings. The service life of composite pipes is affected and limited by the service life of the main materials and thermal expansion. Since composite pipes are a combination of two materials, the bonding layer is highly likely to fall off, which also affects the service life. Many people are interested in the service life of 304 stainless steel. Then the editor will briefly sort it out for everyone.
According to our field corrosion test data, the service life of stainless steel water pipes can be up to 100 years. According to my country's relevant regulations on personal residences, the service life of residences is generally 70 years. This means that stainless steel water pipes can ensure that they do not need to be replaced during use.
For ordinary residents, the house will be used for decades and the decoration will remain unchanged for decades. Therefore, it is important to use a material that will keep pace with life, especially for water pipes. Because it is hidden in the wall or under the floor, maintenance and replacement is a major undertaking.
Many users think that rusty stainless steel pipes are due to quality problems. In fact, this is a one-sided understanding. Stainless steel pipes are just relatively resistant to rust. Stainless steel pipe manufacturers recommend that users choose 304 stainless steel pipes when using stainless steel pipes. Under the same conditions, the rust resistance of 304 stainless steel pipes is 10 times stronger than that of 201 stainless steel pipes.
The service life of 304 stainless steel pipe is usually affected by the following points:
1. Harsh usage environment
304 stainless steel pipe itself has the ability to resist atmospheric oxidation, and also has the ability to corrode in media containing acid, alkali, and salt. Its corrosion resistance varies depending on the chemical composition of the steel, its mutual chemical state, usage conditions and environmental media types. Absolutely excellent corrosion resistance. In dry and clean air, mist with high salt content that moves to a seaside will quickly rust and affect the service life of 304 stainless steel pipes.
For example: Users use 304 stainless steel pipes in highly polluted areas such as seaside sewage treatment plants. When cleaning 304 stainless steel pipes with corrosive chemicals, they will rust.
2. Incorrect processing and installation
When stainless steel processors manufacture products and cut stainless steel pipes or iron, they will splash iron filings on the surface of the steel pipe. 304 stainless steel pipes will rust. If you paint the walls of your house after installing stainless steel products, it may also cause rust.
3. Improper cleaning and maintenance
Do not use a steel ball brush on the surface of the stainless steel pipe, otherwise it will damage the surface of the 304 stainless steel pipe. In addition, do not use bleach and abrasives such as acid and alkali cleaners. Finally, clean the surface of the 304 stainless steel pipe with clean water.
Conclusion:
304 stainless steel pipes have a long service life. Judging from the use of foreign stainless steel pipes, the service life of 304 stainless steel pipes is as long as 100 years and as short as 70 years, which is the same as that of buildings. Of course, the premise is that the quality of the 304 stainless steel pipe you buy is not too bad. The advantage of 304 stainless steel pipes is corrosion resistance. If the stainless steel pipes purchased are of good quality, they can be properly maintained and cleaned during use, effectively extending the life of the 304 stainless steel pipes.
