Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing an exceptional spiral wound gasket, meticulously crafted with an enduring outer ring and an avant-garde inner ring that elevates gasket performance to unparalleled heights. The addition of the inner ring is instrumental in enhancing durability, while the outer guide ring guarantees impeccable alignment on the flange face. This indispensable inner element not only prevents implosion during installation but also provides robust protection against extreme temperatures and aggressive environments. It seamlessly fills the gap between flanges, effectively minimizing erosion risks and significantly lowering failure probabilities. Expertly forged from the same high-caliber alloy as the winding, the inner ring adheres strictly to DIN 2699 standards, ensuring its necessity in all spiral wound gaskets. For gaskets with PTFE filler, ASME B16.20 standards mandate inner rings and acknowledge their critical value for graphite fillers as well. This adaptable profile is perfectly compatible with both raised and flat-faced flanges, with the external ring enhancing radial strength to prevent blowout and serving as an essential compression limiter. The outer ring, typically crafted from corrosion-resistant painted or zinc-plated carbon steel, can optionally be fashioned from alloys to endure elevated temperatures and more rigorous conditions.
