The Fujian Metallic Spiral Wound Gasket is a high-performance sealing solution engineered for demanding industrial applications. This specific configuration—Size: 6 Inch, Class: 900LB, Material: SS304 Inner Ring and Outer Ring, Filler: Flexible Graphite (FG)—conforms strictly to ASME B16.20 standards and is designed for B16.5 flange sealing.
Design and Construction
The gasket employs a sophisticated spiral-wound construction, alternating precision-formed metal windings (typically V- or W-shaped) with layers of soft FG filler material . This design provides exceptional compression and recovery characteristics, creating a reliable, multiple-seal barrier that adapts to pressure fluctuations, temperature cycling, and mechanical vibration . The SS304 inner and outer rings serve critical functions: the outer ring acts as a compression stop and centering guide, while the inner ring provides additional sealing integrity and protects against flange corrosion .
Performance Capabilities
Rated for Class 900LB service, this gasket is validated for demanding pressure-temperature conditions . The FG filler offers excellent chemical resistance and high-temperature stability, while the SS304 components ensure robust performance in corrosive environments.
Application Across Industries
The Fujian Metallic Spiral Wound Gasket proves its versatility across numerous critical sectors:
- Aerospace: Specified for rocket engine manufacturing, withstanding extreme heat and pressure during launch operations.
- Nuclear Power: Essential in reactor primary coolant systems where conventional seals would fail under high-temperature, high-pressure conditions.
- Chemical and Petrochemical Processing: Handles aggressive media and high-pressure piping systems .
