SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket features a robust outer and inner ring, with a specifically engineered inner ring to elevate gasket performance. The inner ring plays a critical role: it accurately centers the gasket on the flange face, prevents the gasket from collapsing into the pipe during installation, and safeguards the sealing element from extreme temperatures and harsh mediums. Furthermore, it fills voids between flanges, prevents flange erosion, and minimizes failure risks. Typically crafted from the same alloy as the winding, the inner ring conforms to the stringent DIN 2699 (German) standard, mandating inner rings for all spiral wound gaskets. As per ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and recommended for graphite fillers. This advanced profile is ideally suited for raised and flat-faced flanges. Additionally, the external guide ring offers superior radial strength to thwart gasket blowout and acts as a crucial compression stop. The outer ring, often made from carbon steel (either painted or zinc-plated to resist corrosion), can also be fabricated from alloys to endure higher temperatures and more demanding applications.
