Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the exceptional engineering of our Spiral Wound Gasket, thoughtfully crafted with both solid outer and inner rings. Experience enhanced performance with an integrated inner ring, skillfully designed to boost gasket reliability during installation. This innovation prevents the risk of gasket implosion into the pipe, safeguarding the sealing element against extreme temperatures and aggressive media, and effectively filling voids between flanges to protect them from erosion. Additionally, the inner ring significantly reduces the likelihood of failure. The inner ring typically matches the alloy of the winding to ensure consistent performance. Adhering to the rigorous DIN 2699 standard, this spiral wound gasket is fitted with inner rings, as mandated for all such gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE fillers and are recommended for those with graphite fillers. This robust profile is ideally suited for raised and flat-faced flanges, delivering reliability in every application. The external guide ring precisely centers the gasket on the flange face, providing additional radial strength to prevent blowouts and serving as a dependable compression stop. Typically made of carbon steel, which is either painted or zinc plated to combat corrosion, the outer ring can also be composed of alloys for demanding high-temperature applications and severe media conditions.
