Spiral Wound Gaskets
Spiral wound gaskets have proven themselves to be the most reliable sealing element in piping and equipment applications. They are designed to provide superior sealing performance in demanding industrial environments.
The gasket consists of a spirally wound V-shaped metal strip and a soft filler material. The metal provides strength and resilience while the filler material provides excellent sealing capabilities. This combination makes spiral wound gaskets ideal for high-pressure and high-temperature applications.
Available in various sizes and materials to suit your specific application requirements.
1. With Outer Guide Ring
The outer ring centers the gasket on the flange and provides additional radial strength. Ideal for applications where precise centering is critical.
2. With Inner & Outer Ring
Provides maximum stability and prevents inward buckling. The most commonly specified type for standard flanged connections.
3. With Inner Ring
Inner ring prevents inward buckling and protects against erosion from high-velocity gases or fluids.
4. Without Ring (Basic Type)
Most economical option. Suitable for applications with proper bolt alignment and adequate compression.
