SS304 Inner Ring Spiral Wound Gasket – ASME B16.20 Standard
The SS304 Inner Ring Spiral Wound Gasket is a high-quality metallic gasket manufactured in full compliance with ASME B16.20, ensuring precise dimensions, dependable sealing performance, and compatibility with standard industrial flanges. It is engineered for use in a wide range of pressure and temperature applications, providing a durable and reliable seal under demanding conditions.
Size and Pressure Rating
This gasket is specified for a 6-inch nominal size with a Class 150 pressure rating, making it suitable for low to medium pressure systems such as pipelines, valves, and flanged connections in oil and gas, petrochemical, power generation, and water treatment industries.
Material and Construction
The gasket is constructed with a 304L stainless steel (SS304L) hoop wound with flexible graphite (FG) filler, combining the mechanical strength of stainless steel with the excellent sealing properties of graphite. The inner ring and centering ring are made from stainless steel 304 (SS304), providing strong corrosion resistance, structural stability, and precise flange alignment. The outer ring is made from carbon steel (CS), offering additional rigidity and resistance to mechanical deformation during installation.
Design Features
This spiral wound gasket features both an inner ring and a centering ring, ensuring optimal compression control and protection against overloading. The inner ring enhances sealing reliability by preventing inward buckling and shielding the filler from erosion or chemical attack. The centering ring provides accurate positioning within the flange assembly, ensuring even pressure distribution for a consistent, leak-free seal.
Applications
The ASME B16.20 SS304 Spiral Wound Gasket with FG Filler is ideal for sealing steam, gas, oil, and chemical process lines. Its robust design and high adaptability to thermal and mechanical fluctuations make it a preferred choice for industrial systems requiring long-term sealing integrity and maintenance-free performance.
