SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This meticulously engineered spiral wound gasket showcases a robust design featuring solid outer and inner rings. An inserted inner ring enhances the gasket's performance by ensuring accurate centering on the flange face and preventing any potential implosion into the pipe during installation. This crucial component also shields the sealing element from extreme temperatures and aggressive mediums, fills voids between flanges to avert erosion, and minimizes the risk of failure. Constructed from the same alloy as the winding, the inner ring meets DIN 2699 standards, making it a staple in all spiral wound gaskets. For gaskets with PTFE and graphite fillers, the inclusion of inner rings is mandated by ASME B16.20 standards due to their significant role in maintaining integrity. This spiral wound gasket configuration is ideal for raised and flat-faced flanges. The external guide ring adds radial strength, preventing blowouts and acting as a compression stop. Typically made of carbon steel (with protective paint or zinc plating for corrosion resistance), the outer ring can also be crafted from specialized alloys for higher temperature and more demanding applications.
