Sealmax Style 930
Sealmax Style 930 – Spiral Wound Gaskets are high-performance metallic sealing solutions designed for demanding service conditions involving high pressure, high temperature, and fluctuating operating parameters.
Style 930 consists of a V-shaped metal winding strip spirally wound with a soft filler material, providing excellent resilience, recovery, and sealing integrity across a wide range of industrial applications.
Style 930 is available in standard configurations as well as customized sizes and designs to suit specific flange dimensions and operating requirements. These gaskets are manufactured in accordance with ASME B16.20 and other relevant international standards, ensuring reliable performance in critical flange joints.
- Metal Winding Strip – provides mechanical strength and resilience
- Soft Filler Material – ensures sealing performance and conformability
- Outer Ring (optional) – ensures proper centering and prevents over-compression
- Inner Ring (optional) – enhances sealing performance and protects winding from process media
Available configurations (drawings provided at the end):
- Basic Type (without rings) – recommended for tongue and groove flanges
- With Outer Ring – recommended for raised face and flat face flanges; ensures proper centering and prevents over-compression
- With Inner and Outer Ring – recommended for raised face and flat face flanges; this type prevent turbulence, protects flanges from erosion, and shields the inner winding from high temperatures
- With Inner Ring – recommended for male – female flanges
- Excellent sealing performance under extreme pressure and temperature conditions
- High mechanical strength and blowout resistance
- Outstanding recovery and resilience
- Suitable for cyclic loading and thermal fluctuations
- Wide chemical compatibility depending on filler selection
- Available in standard and customized dimensions
