Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover our Spiral Wound Gasket, thoughtfully engineered with a robust solid outer and inner ring. An innovative inner ring has been meticulously inserted to significantly enhance the gasket's performance. This enhancement serves multiple crucial purposes: it ensures precise centering on the flange face with an external guide ring, offers a safeguard against implosion during installation, and provides effective protection for the sealing element against extreme temperatures and aggressive mediums. Additionally, it fills the void between flanges to prevent erosion and significantly reduces the risk of failure. The inner ring matches the alloy of the winding, adhering to the DIN 2699 standard (German), which mandates inner rings for all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and hold great importance for those with graphite fillers. Ideally suited for raised and flat faced flanges, this profile offers exceptional reliability. The external ring is designed to enhance radial strength, preventing potential blowouts while acting as a reliable compression stop. Typically crafted from carbon steel, it features a painted or zinc-plated finish to resist corrosion, though it can also be fabricated from specialized alloys to withstand higher temperatures and more severe conditions. This profile is your trusted choice for both raised and flat faced flanged applications.
