Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Behold the pinnacle of sealing technology with our Graphite Spiral Gasket featuring JIS Compliance and SS347 Winding, crafted by Ningbo Dongheng Sealing Co., Ltd. This remarkable spiral wound gasket is meticulously engineered with robust outer and inner rings, ensuring superior performance and reliability. The inner ring, a crucial component, has been thoughtfully inserted to bolster gasket performance by preventing implosion into the pipe during installation and safeguarding the sealing element against extreme temperatures and aggressive mediums. Moreover, it fills the void between flanges, shielding them from erosion and significantly minimizing the risk of failure. Crafted from the same alloy as the winding, the inner ring aligns with the stringent DIN 2699 standard (German) that mandates inner rings in all spiral wound gaskets. Essential for gaskets with PTFE fillers as per ASME B16.20 standards, this inner ring is also deemed vital for those with graphite fillers. The profile's versatility allows it to be adeptly used in both raised and flat-faced flanges. Complementing this, the external guide ring precisely centers the gasket on the flange face, providing additional radial strength to avert blowouts, acting as a reliable compression stop. Typically composed of carbon steel, painted or zinc-plated to ward off corrosion, the outer ring can also be constructed from specialized alloys to withstand higher temperatures and more severe mediums, making it an ideal choice for demanding applications.
