Lifespan of Metal Bellows

The lifespan of metal bellows is affected by many factors, including the operating environment, working conditions, and material manufacturing processes. In corrosive environments (such as chemical workshops and coastal areas with high salt spray), the lifespan may be shortened to 1-3 years; while in dry, non-corrosive indoor environments, the lifespan can reach 10-20 years. Operating pressure (high pressure or frequent fluctuations) accelerates fatigue damage; stable low pressure conditions result in a longer lifespan. Products using high-quality materials (such as high-corrosion-resistant alloys) and precision manufacturing processes (reducing stress concentration) typically have a lifespan of 8-15 years. Overall, the lifespan range of metal bellows is 1-20 years, and appropriate parameters need to be selected based on the specific application scenario (such as chemical pipeline sealing and hydraulic system buffering).
