Factors effecting gasket performance
There are many factors effecting gasket performance
A gasket creates a positive seal between two stationary parts. To function properly, a gasket must create an initial seal, and then maintain the seal over a desired length of time. When the useful life is complete, a gasket should be easily removed in order to be replaced. Optimal gasket performance is dependent on how well the gasket functions.
Factors affecting gasket sealing performance
1. Seals system fluid.
2. Chemically resists system fluid to prevent serious impairment of its physical properties.
3. Deforms enough to flow into the imperfections on the gasket seating surfaces to provide intimate contact between the gasket and the sealing surfaces.
4. Withstands system temperatures without serious impairments of its performance properties.
5. Is resilient and creep resistant enough to maintain an adequate portion of the applied load.
6. Has sufficient strength to resist crushing under the applied load, and maintain its integrity when being handled and installed.
7. Does not contaminate the system fluid.
8. Does not promote corrosion of the gasket sealing surfaces.
9. Is easily and cleanly removable at replacement.
During the gasket product selection process that follows, Sealing Devices recommends that these factors be used as a checklist to determine optimal seal performance for your application.
Here are some critical items to consider when choosing gasket materials, including correct bolting patterns recommendations for common configurations.
- There are also Size, temperature, application, media, pressure (STAMPS) guidelines for improving gasket sealing performance. Insure correct bolt-torque, and re-torque within 24 hours.
