SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Introducing an advanced spiral wound gasket enhanced with a robust outer and inner ring. The strategically inserted inner ring elevates performance by ensuring precise centering on the flange face, safeguarding against potential implosion into the pipe, and shielding the sealing element from extreme conditions. This essential addition fills flange voids, preventing erosion, and significantly reduces failure risks. Crafted typically from the same alloy as the winding, the inner ring aligns with the DIN 2699 German standard, mandating its presence in all spiral wound gaskets. It is particularly crucial for gaskets with PTFE fillers as per ASME B16.20 standards and is highly recommended for those with graphite fillers. This design is adept for both raised and flat-faced flanges. Complementing the design, the external guide ring, often forged from carbon steel and optionally painted or zinc-plated, offers additional radial strength, acts as a compression stop, and shields against gasket blowout. For higher temperature and more demanding applications, alloy-made outer rings are available, ensuring unparalleled durability and reliability.
