Overview
This 16-inch spiral wound gasket is engineered for high-pressure, high-temperature sealing in critical industrial flange connections. Designed to meet the rigorous ASME B16.20-2007 standard, it is constructed for service in demanding chemical, petrochemical, and power generation applications. The C-shaped, metal-wound design with a graphite filler provides superior resilience and sealing force, ensuring long-term leak prevention even under variable pressures and thermal cycling. The inclusion of a solid outer ring facilitates proper alignment during installation and protects the winding from damage.
Key Features
Manufactured to ASME B16.20-2007 standards for guaranteed dimensional accuracy and performance. Constructed with 316L stainless steel for both the outer ring and the metal winding, offering excellent corrosion resistance. Graphite filler material provides reliable sealing across a wide temperature range and is chemically inert in many services. The solid 316L stainless steel outer ring (C-type with outer ring) ensures easy centering on the flange and protects the vulnerable winding. Engineered for high-pressure applications with a rating of 900LB, suitable for severe service conditions. Spiral wound design allows for compression and recovery, maintaining a tight seal under fluctuating pressures and temperatures.
