ASME B16.20 Spiral Wound Gasket, 2 Inch NPS 900LB, with Inner and Outer Rings
Overview
This precision-engineered spiral wound gasket is manufactured in strict compliance with the ASME B16.20-2007 standard, ensuring reliable performance in high-pressure, high-temperature piping systems. Designed specifically for NPS 2 inch, Class 900LB steel pipe flanges, it provides a robust and leak-tight seal for critical industrial applications. The construction incorporates a resilient graphite filler wound with a metallic strip, reinforced by both inner and outer retaining rings. This design delivers superior sealing integrity under variable pressures and thermal cycling, making it an essential component for maintaining system safety and efficiency.
Key Features
Full compliance with ASME B16.20-2007 standard for dimensional consistency and performance. Engineered for Class 900LB flange pressure ratings, suitable for demanding service. Dual retaining ring design with inner and outer rings constructed from 304 stainless steel. Outer ring centers the gasket on the flange for easy installation. Inner ring provides internal support to prevent gasket buckling and over-compression into the pipe bore. Resilient graphite filler provides excellent conformability and a reliable seal across a wide temperature range. V-ring construction allows the gasket to compensate for minor flange irregularities and bolt stress fluctuations. Designed specifically for use with standard steel piping systems.
