Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing a groundbreaking spiral wound gasket, meticulously designed to offer unparalleled reliability and performance in demanding environments. It boasts a robust outer ring paired with an innovative Alloy20 inner ring, creating a harmonious synergy that dramatically enhances the gasket's functionality. The inner ring is a marvel of engineering, expertly preventing implosion during installation and offering formidable protection against extreme temperatures and aggressive mediums. This essential component fills the flange gap with precision, effectively mitigating erosion risks and significantly reducing failure potential. Crafted from high-grade alloy, the inner ring adheres strictly to the DIN 2699 standard, underscoring its necessity in all spiral wound gaskets. For those with PTFE fillers, ASME B16.20 standards make inner rings compulsory, acknowledging their critical role with graphite fillers as well. This versatile profile fits seamlessly with both raised and flat-faced flanges, boasting an external guide ring that enhances radial strength to prevent blowout and serves as a crucial compression stop. The outer ring, typically made from corrosion-resistant carbon steel—either painted or zinc-plated—ensures longevity and can be customized with alloys for superior temperature resilience and performance in challenging environments.
