Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our meticulously engineered spiral wound gasket, complete with a robust outer and inner ring construction. An integrated inner ring has been expertly inserted to significantly boost the gasket's performance. This essential component not only ensures precise alignment on the flange face with its external guide ring, but also provides unparalleled protection for the sealing element against extreme temperatures and harsh mediums. The inner ring adeptly fills the void between flanges, safeguarding them from erosion and mitigating the risk of gasket failure. Crafted typically from the same high-quality alloy as the winding, the inner ring complies with the DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. As per ASME B16.20 standards, inner rings are essential for gaskets with PTFE fillers, and highly recommended for those with graphite fillers. Designed for both raised and flat-faced flanges, the external ring further enhances radial strength, effectively preventing gasket blowout and serving as a reliable compression stop. While often composed of corrosion-resistant painted or zinc-plated carbon steel, the outer ring is also available in various alloys, catering to higher temperature and more demanding applications.
