The service life of metal seals is a relatively complex issue, because it is affected by a variety of factors, including but not limited to working conditions, medium properties, use environment, mode of transport, material, quality, installation method and storage conditions.
Service life under normal circumstances
In general, the normal service life of metal seals may be between 1 and 3 years. However, it should be noted that this is only a rough range, and the actual service life may vary due to the above factors.
Under certain conditions, such as high temperature, high pressure or corrosive media, the service life of metal seals may be shortened. On the contrary, in a milder use environment, its service life may be longer.
How the service life is calculated
For metal seals used in short-stroke mechanisms or hydraulic components, their service life can be calculated according to the number of operations, generally 150,000 to 250,000 times.
For metal seals used in long-stroke hydraulic cylinders, their service life may be calculated according to the mileage of the movement, generally between 100 and 1500 km.
For metal seals with static seals, their service life may be calculated according to the actual use time, generally 1.5 to 20,000 hours or 1.5 to 2 years.
Methods for extending service life
In order to extend the service life of metal seals, you can start from the following aspects:
Select the right material: According to the specific use environment and requirements, select metal materials with excellent high temperature resistance, high pressure resistance, corrosion resistance and other properties.
Optimized design and installation: Ensure that seals are properly designed and correctly installed to avoid damage or leakage caused by improper installation during installation.
Maintain a good working environment: reduce the adverse factors such as pollutants and corrosive substances in the environment of the seals, and reduce the damage to the seals.
Regular maintenance and inspection: Regular inspection and maintenance of seals, timely detection and treatment of potential problems, to prevent the expansion of problems resulting in seal failure.
Matters needing attention
It should be noted that the shelf life and service life of metal seals are two different concepts. Shelf life usually refers to the time that the seal can maintain its performance and function without loss during storage, while the service life refers to the effective working time of the seal in actual use.
In the process of use, if the metal seal is found to leak, deformation or other abnormal conditions, it should be replaced or repaired in time to ensure the normal operation and safety of the equipment.
To sum up, the service life of metal seals is a complex issue affected by many factors, and cannot be simply given a definitive answer. However, by choosing the right material, optimizing the design and installation, maintaining a good working environment and regular maintenance and inspection measures, the service life of metal seals can be effectively extended.
