Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This remarkable spiral wound gasket is equipped with both a solid outer and inner ring, enhanced by the addition of an inner ring to elevate gasket performance to exceptional levels. An expertly crafted external guide ring ensures precise centering of the gasket on the flange face, a critical feature to prevent any inadvertent implosion into the pipe during installation. This innovative design also protects the sealing element from harsh temperatures and challenging mediums, while meticulously filling the void between flanges to avert flange erosion and minimize failure risks. Crafted predominantly from the same alloy as the winding, the inner ring adheres to the rigorous DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and highly recommended for those with graphite fillers. Ideal for both raised and flat-faced flanges, the design incorporates an external ring offering additional radial strength to avert gasket blowout and serving as a compression stop. Typically crafted from carbon steel, either painted or zinc-plated to resist corrosion, the outer ring can also be tailored from specialized alloys for heightened temperature resilience and more demanding applications.
