[Case Study] Replacement of Metal Seals (Spring-Loaded Seals)
Reusing the seal is possible at the customer's discretion! We are applying surface pressure using the elasticity of the spring!
【Issues】 When installing a metal seal, a mirror finish of generally 0.4Rmax or higher is essential. This has led to problems such as the inability to reuse seals and the hassle of regrinding. 【Improvements and Effects】 The spring-loaded seal uses Teflon as the main sealing material and applies surface pressure using the elasticity of the spring. Therefore, it does not damage the hardware during installation. For fluids that are prone to leakage (such as cryogenic temperatures, helium gas, and hydrogen gas), a finish of 0.4 to 0.8Rmax is required, but generally, a finish of 0.8 to 1.6Rmax is sufficient for use. *For more details, please refer to the PDF document or feel free to contact us.
