SS316 Spiral Wound Gasket – ANSI B16.20, 6 Inch, Flexible Graphite Filled, CGI Type

This SS316 Spiral Wound Gasket is engineered to provide exceptional sealing performance in demanding industrial applications, particularly for flanged joints conforming to ANSI B16.5 standards. Designed to withstand high pressures and temperatures, it offers reliable, long-lasting sealing solutions for critical pipeline systems.

Key Features:

• Gasket Type: Spiral Wound Gasket (CGI Type) — features a combination of winding stainless steel strips and filler materials, designed to maintain tight sealing under varying temperature and pressure conditions.

• Standard: Manufactured in accordance with ANSI B16.20, the recognized standard for spiral wound gaskets used in piping flanges.

• Size: Specifically sized for 6-inch flange connections, suitable for mid-sized piping systems.

• Material Composition:

  • Metallic Component: Made from Stainless Steel 316 (SS316), known for its excellent corrosion resistance, mechanical strength, and durability, suitable for harsh and corrosive environments. Both the inner ring and outer ring are fabricated from SS316 for enhanced protection and sealing performance.

  • Filler Material: Filled with Flexible Graphite, which offers excellent compressibility, resilience, and thermal stability. Flexible graphite ensures tight sealing, compensating for flange surface irregularities and thermal expansion.

• Design Pressure: Rated for 300 LB (Class 300) service pressure, making it appropriate for moderate to high-pressure applications.

• Type: CGI Type — Spiral wound gasket with concentric inner and outer rings designed for use with ANSI B16.5 flanges, providing stable sealing under dynamic conditions and preventing gasket blowout.

Applications:

• Widely used in oil and gas, petrochemical, power generation, and chemical processing industries.

• Suitable for sealing pipelines transporting steam, gases, liquids, and other aggressive fluids requiring high-integrity flange connections.

• Ideal for applications requiring a combination of corrosion resistance and mechanical strength in flange sealing.

Benefits:

• Excellent Sealing Reliability: The spiral wound design allows for high resilience and tight sealing even under fluctuating temperature and pressure.

• Corrosion Resistance: SS316 rings resist corrosion from a variety of chemicals, ensuring extended gasket life.

• Thermal Stability: Flexible graphite filler withstands high temperatures and provides excellent compressibility and recovery.

• Flange Protection: Inner and outer stainless steel rings protect the flange faces from damage during gasket compression.Know more about China Manufacturer
