Overview
This industrial-grade spiral wound gasket is engineered for high-integrity sealing in critical piping and vessel flanges. Manufactured in strict compliance with ASME B16.20-2007 standards, it is designed for nominal pipe sizes of 24 inches with a 150-pound pressure class rating. The gasket features a robust construction combining a 316L stainless steel outer ring with spiral windings of 316L stainless steel filled with flexible graphite. This design delivers a reliable, pressure-energized seal capable of withstanding thermal cycling, system vibration, and mechanical stress, making it a trusted solution for demanding process environments.
Key Features
ASME B16.20-2007 compliant construction for guaranteed dimensional accuracy and performance 316L stainless steel outer centering ring ensures proper flange alignment and prevents gasket blow-out Spiral wound core with alternating layers of 316L stainless steel and flexible graphite filler
Graphite filler provides excellent thermal conductivity and resilience across a wide temperature range Pressure-energized seal that increases sealing force as internal system pressure rises Suitable for applications involving thermal cycling and vibration due to its flexible, recovery-enabled design
Intended for indoor use in controlled industrial environments
