ASME B16.20 Metal Gasket – Spiral Wound Type
The ASME B16.20 Metal Gasket is a spiral wound gasket engineered for reliable sealing performance in a wide range of industrial applications. Designed and manufactured in accordance with ASME B16.20, it ensures precise dimensions, consistent quality, and compatibility with standard flange connections.
Design and Construction
This gasket features a spiral wound construction consisting of alternating layers of stainless steel 304/304L (SS304/304L) hoop material and flexible graphite filler. The combination of these materials provides an excellent balance of mechanical strength, chemical resistance, and resilience to temperature and pressure variations.
The gasket includes both an inner ring made from stainless steel 304/304L and a centering ring made from carbon steel (CS). The inner ring enhances structural stability, prevents inward buckling, and protects the filler from erosion or media attack. The carbon steel centering ring ensures proper gasket alignment within the flange, controls compression during tightening, and adds rigidity to the overall assembly.
Pressure Rating
Designed for Class 150LB pressure service, this gasket is suitable for low to medium pressure systems while maintaining excellent sealing integrity under thermal and mechanical stress.
Material Advantages
- Stainless Steel 304/304L: Offers outstanding corrosion resistance, oxidation resistance, and durability in a wide range of temperatures and process media.
- Flexible Graphite Filler: Provides superior sealing adaptability, excellent compressibility, and long-term resistance to heat and chemicals.
- Carbon Steel Centering Ring: Adds mechanical strength and stability during installation and operation.
Applications
The ASME B16.20 Spiral Wound Metal Gasket with CS centering ring, SS304/304L inner ring, and flexible graphite filler is widely used in oil and gas, petrochemical, power generation, chemical processing, and marine industries. It provides a dependable, leak-free seal for steam lines, valves, pumps, and pipeline flanges, even under fluctuating temperature and pressure conditions.
