Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Unveiling a pioneering spiral wound gasket, expertly engineered with a durable outer ring and a cutting-edge Monel inner ring, alongside precision graphite winding. The Monel inner ring significantly amps up the gasket's performance, while a skillfully crafted external guide ring ensures perfect centering on the flange face. This indispensable inner element not only prevents the gasket from collapsing during installation but also provides protection against extreme temperatures and aggressive environments. It efficiently seals the gap between flanges, reducing erosion risk and significantly minimizing failure potential. Made from the same premium alloy as the spiral winding, the inner ring meets the rigorous DIN 2699 standard, which mandates its inclusion in all spiral wound gaskets. For those with PTFE filler, the ASME B16.20 standards require inner rings, underscoring their critical role in graphite applications too. This adaptable design is perfectly tailored for both raised and flat-faced flanges, with the external ring enhancing radial strength to prevent blowout and serving as an essential compression stop. The outer ring, typically made from painted or zinc-plated carbon steel to resist corrosion, can also be optionally crafted from specialized alloys to endure higher temperatures and more demanding environments.
