1. Many factors affect service life
Under normal working conditions, the expected service life of Stainless Steel Airtight Parts is affected by a variety of factors, making it difficult to give an exact fixed value. First of all, the medium in the working environment has a significant impact on its service life. If the medium is corrosive, even if stainless steel itself has certain corrosion resistance, the corrosion effect may gradually weaken the structural integrity of the seal over time. For example, in the chemical industry, Stainless Steel Airtight Parts that are exposed to acidic or alkaline solutions for a long time may have a significantly shorter service life than seals that work in a neutral medium environment.
2. The role of pressure and temperature
The pressure and temperature experienced while working are also key factors. At higher pressures, Stainless Steel Airtight Parts are required to withstand greater stresses, which can cause microscopic deformation of the seal. If this deformation exceeds its elastic limit, it will cause fatigue damage to the seal, thereby affecting the sealing effect and shortening its service life. Similarly, changes in temperature will change the physical properties of stainless steel. High temperatures may reduce the hardness of stainless steel, and low temperatures may cause its toughness to decrease. For example, Stainless Steel Airtight Parts that continue to work in high-temperature environments may gradually lose their sealing ability due to thermal expansion and softening of the metal, and their service life may be reduced as the temperature increases.
3. The quality and design of the seal itself
The quality and design of Stainless Steel Airtight Parts themselves also have an important impact on their service life. High-quality Stainless Steel Airtight Parts are more secure in terms of material purity, processing accuracy and manufacturing technology. For example, seals manufactured using advanced forging and precision machining processes have a more uniform internal structure, higher dimensional accuracy, and can better withstand various stresses during work. In terms of design, if the seal has a reasonable structure that can evenly distribute pressure and reduce stress concentration points, it will be less likely to be damaged under normal operating conditions and its service life will be extended accordingly.
4. Approximate range under normal working conditions
Although it is difficult to determine a precise value, under normal operating conditions, that is, when the medium is relatively mild, the pressure and temperature are within a moderate range, and the seals are of good quality and properly designed, the expected service life of Stainless Steel Airtight Parts may be several years. It can vary from several decades to several decades. For some lightly used and relatively stable working environments, such as Stainless Steel Airtight Parts in ordinary plumbing systems, they may be used for ten years or even longer. In some industrial environments, although it is normal working conditions, it is relatively complex. For example, in some equipment in the food processing industry, the service life may be about 3-5 years. However, this is only a rough range, and the actual service life still needs to be evaluated based on the specific working environment and usage.
