How Long is the Service Life of Vacuum Stainless Steel Bellows?
The service life of stainless steel bellows is very long, about 5-7 years, but many people will ask, is there any way to increase the service life of vacuum stainless steel bellows and make it last longer?
The main factors affecting the service life of the stainless steel bellows are the correct installation of the stainless steel bellows, the control of the working environment, and the manufacturing process.
- Correct selection and installation of stainless steel bellows: Whether it is installed properly or not is directly related to the service life of the bellows. There are many products on the market. No matter what choice is made, make sure to use the same bellows and not mix them at will.
- Use environment: Try to avoid long-term exposure and long-term direct exposure, which may cause deformation of the bellows and affect its life.
- Use skills: Do not use overloaded, the greater the load, the service life of the bellows will be reduced, and it must be used within the allowable range of the bellows and should not be exceeded.
- Learn to see: Look at the craftsmanship, choose high-quality bellows, and check for damage when buying.
Although the calculation and evaluation of several aspects of the national standard and the American EJMA standard have clear regulations, it is found that the stability of the calculation and evaluation method given in the standard is not comprehensive from the practical application and failure analysis of stainless steel bellows for many years.
In addition, sometimes it is not ruled out that a product that fully meets the required standards may have some problems in actual use. The large deformation of stainless steel bellows not only affects the stability, but also provides favorable environmental conditions for stress corrosion.
