SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This spiral wound gasket is meticulously designed with a robust outer and inner ring. An inner ring is thoughtfully incorporated to amplify gasket performance, while an external guide ring precisely centers the gasket on the flange face. Key advantages of the inner ring include preventing potential implosion during installation, shielding the sealing element from extreme conditions, filling voids to prevent flange erosion, and minimizing failure risks. Constructed of the same alloy as the winding, the inner ring is mandated by DIN 2699 standards for all spiral wound gaskets. ASME B16.20 standards specify inner rings for gaskets with PTFE filler and deem them crucial for graphite fillers. Ideal for both raised and flat-faced flanges, the external ring bestows additional radial strength, averts gasket blowout, and serves as a compression stop. Typically, the outer ring is manufactured from carbon steel, either painted or zinc-plated for corrosion resistance, but can also be made from specialized alloys for high-temperature and severe-medium applications.
