Quantity
The Zhejiang SS316 Spiral Wound Gasket is a premium semi-metallic sealing solution engineered for critical flange connections in demanding industrial environments. Manufactured in strict accordance with ASME B16.20 and designed for ASME B16.5 flanges, this 6-inch, Class 300LB gasket delivers exceptional reliability where high pressure, elevated temperatures, and corrosive media are present .
Construction & Materials
This gasket features a robust SS316L inner ring that prevents buckling of the spiral winding into the pipe bore under vacuum or pressure cycling conditions, paired with a Carbon Steel (CS) outer ring that provides precise centering and compression control during installation . The sealing element comprises an alternating spiral wound of SS316 metal strip and high-performance Flexible Graphite (FG) filler, creating a resilient structure that compensates for thermal cycling, bolt creep, and flange surface irregularities .

Performance Characteristics
The SS316 winding provides excellent corrosion resistance against seawater, acids, and chloride-containing fluids, while the graphite filler maintains sealing integrity up to approximately 550°C . The gasket's spring-like recovery properties ensure leak-tight performance under fluctuating pressure and temperature conditions, with a maximum operating pressure capacity up to 45 MPa depending on flange rating .
