Spiral Wound Gaskets

Product Details:

This is a 2-inch, high-performance spiral wound gasket (SWG) with an SS304 metal winding and graphite filler, featuring a Carbon Steel (CS) outer guide ring, designed for excellent resilience, temperature/pressure stability (often Class 900+), and easy centering on flanges, ideal for fluctuating conditions in oil, gas, and chemical industries, preventing blowouts and flange erosion. Key Features & Breakdown:

• SS304 (Stainless Steel 304): The winding metal, offering corrosion resistance and strength for standard industrial uses.
• Graphite Filler: A soft, resilient material providing superior sealing, high-temp resistance (up to 550°C/1000°F), and chemical stability, even with imperfect flange faces.
• CS Outer Ring (Carbon Steel): Acts as a centering and compression-limiting stop, protecting the windings, preventing flange erosion, and ensuring correct placement on the flange.
• 2-inch Size: Specifies the nominal pipe size (NPS) it's designed for, with specific dimensions for flange compatibility.
• Spiral Wound: The construction of alternating metal and filler layers provides outstanding resilience and self-adjusts to pressure/temperature changes. 

Applications:

• High-pressure/temperature services (Class 900 and above).
• Fluctuating temperature/pressure conditions.
• Flanges requiring centering (Raised Face, Flat Face).
• Petrochemical, power, chemical, and general industrial piping.

Product Details:

This is a description for a 1-inch, Class 150, SS304 spiral wound gasket with a Carbon Steel (CS) outer guide ring, designed for piping systems, featuring a flexible metal winding (usually SS304) with a soft filler (like graphite) to seal flanges, where the outer ring centers the gasket and prevents over-compression, ideal for moderate pressures/temps, meeting ASME B16.20 standards. Detailed Breakdown:

• SS304: The metal winding inside the gasket is made from Grade 304 Stainless Steel, offering good corrosion resistance.
• Spiral Wound: The sealing element is formed by winding a V-shaped metal strip (SS304) and a soft filler material (typically flexible graphite) together, providing resilience and sealing under pressure.
• 150# (Class 150): Denotes the pressure class, indicating it's for standard low-to-moderate pressure applications, per ASME B16.5 flange standards.
• CS Outer Ring (Carbon Steel): An outer solid metal ring that centers the gasket on the flange, acts as a compression stop, and protects the windings from blowout and erosion.
• 1" (One Inch): The nominal pipe size (NPS) the gasket is designed for, meaning it fits 1-inch flanges.
• ASME B16.20: The manufacturing standard for spiral wound gaskets, ensuring quality and interchangeability with ASME B16.5 flanges.
