Spiral Wound Gaskets
Spiral wound gaskets are one of the most reliable sealing solutions for high pressure and high temperature flange connections, making them a core offering at GasketZone.com. Manufactured in accordance with ASME B16.20, these gaskets are constructed from alternating layers of formed metal strip and soft filler material that work together to create a tight, resilient seal. The V shaped metal winding acts like a spring, allowing the gasket to maintain sealing stress even as operating conditions fluctuate. By selecting different metal alloys and filler materials, spiral wound gaskets can be tailored to meet a wide range of chemical compatibility and service requirements.
Spiral wound gaskets are available with outer centering rings, inner rings, or both, depending on the application. The centering ring ensures proper alignment within the flange and helps control compression, while the inner ring adds radial strength, minimizes flange erosion, and protects the sealing element from process media. Known for their strength, flexibility, and durability, spiral wound gaskets are widely used in refineries, chemical processing plants, power generation facilities, aerospace applications, and demanding valve and specialty services. In line with current ASME recommendations, graphite filled spiral wound gaskets are typically supplied with inner rings unless otherwise specified, while remaining fully compliant and stamped to the ASME B16.20 standard.
