The service life of stainless steel flanges is generally between 20 and 70 years. Although the shelf life of stainless steel flanges can theoretically be considered indefinite, in practical use, their service life will be affected by various factors.

Firstly, the service life of the material is one of the important factors affecting the lifespan of stainless steel flanges. Generally speaking, the service life of stainless steel flanges is about 20 years.

In high-frequency usage scenarios, maintenance and inspection work should be strengthened to ensure the performance and safety of the flange.

Finally, different types of stainless steel materials can also affect the service life of flanges. For example, 304 and 316 are two common stainless steel materials with different corrosion resistance and applicable environments.
