The service life of metal bellows is a relatively complex issue, because it is affected by many factors, including the use of the environment, the material of the pipe, the quality of the bellows themselves, and the way of use and maintenance.

In general, the service life of metal bellows can be quite long, but the specific time will vary due to the above factors. From the publicly released information, the service life of metal bellows can range from a few years to several decades. For example, it is pointed out that the normal life of a good bellows is more than 50 years, but this is the conclusion reached under the ideal use environment. In actual use, metal bellows may shorten their service life due to long-term exposure to humidity, exposure to sunlight or other adverse factors.

For products such as stainless steel metal bellows, their service life is usually longer. Data show that the service life of stainless steel corrugated metal hoses can reach 8-10 years. However, this does not mean that all stainless steel metal bellows can achieve this life, because other factors such as the use of the environment, installation quality, use, etc., need to be considered.

In addition, the method of improving the service life of metal bellows is also worth noting. For example, the correct selection and installation of metal bellows, avoiding long-term exposure and overload use, choosing high-quality bellows and regular inspection and maintenance can extend their service life to a certain extent.

In summary, the service life of metal bellows is a relatively flexible concept, and the specific time needs to be evaluated according to the actual situation. In order to ensure its long-term stable operation, it is recommended that users pay attention to the above factors during use, and take appropriate measures for maintenance and maintenance.
