Stainless Steel Inner & Outer Rings with Graphite Filler Spiral Wound Gaskets: Ultimate Corrosion Resistance for Severe Environments
For applications where atmospheric corrosion, aggressive chemical media, or external washdowns rule out standard carbon steel, the All-Stainless Steel Ring Style CGI spiral wound gasket is the ultimate choice.
Featuring both a stainless steel outer ring and a stainless steel inner ring paired with a flexible graphite filler, this configuration offers maximum structural integrity and uncompromised protection against harsh environments.
This premium sealing solution is designed for critical piping systems where component failure is not an option and where the external environment is just as demanding as the internal process.
Key Feature Breakdown:
- Stainless Steel Outer Ring: Unlike carbon steel rings, an all-stainless outer ring (such as 304 or 316L) will not rust, scale, or degrade when exposed to coastal salt air, chemical splashes, or rigorous clean-in-place (CIP) washdowns. This guarantees long-term flange alignment and easy removal during maintenance.
- Stainless Steel Inner Ring: Provides robust internal reinforcement. It eliminates the risk of vacuum collapse, prevents filler extrusion, and creates a smooth, non-turbulent flow path while resisting aggressive internal media.
- Flexible Graphite Filler: Offers exceptional chemical resistance across a broad pH range (0-14) and maintains a reliable, highly resilient seal during extreme thermal cycling up to 450°C (840°F).
Ideal Applications:
- Offshore oil rigs and marine environments where saltwater corrosion degrades standard metals.
- Chemical processing plants handling aggressive fluids or operating in corrosive atmospheres.
Pharmaceutical and food processing facilities requiring cleanable, highly sanitary, and rust-free external components.
