SPIRAL WOUND GASKET
Product Type: XINSEN-SD
Features:
Introducing a marvel of engineering: the 5" 300# spiral wound gasket, a semi-metallic masterpiece utilizing PTFE filler. This gasket is designed with a solid outer and inner ring, but what truly sets it apart is the strategically inserted inner ring. This ingenious addition not only elevates gasket performance but also ensures precise alignment on flange faces with an external guide ring. The inner ring acts as a guardian for the sealing element, shielding it from harsh temperatures and corrosive mediums, while filling voids between flanges to thwart flange erosion and mitigate failure risks. Fabricated typically from the same alloy as the winding, the inner ring adheres to strict DIN 2699 standards and is crucial for PTFE fillers as per ASME B16.20 standards, making it indispensable for gaskets with graphite fillers too. This superior profile is perfectly suited for both raised and flat-faced flanges. Meanwhile, the robust external ring bestows additional radial strength to ward off gasket blowout and functions as a compression stop. Often crafted from carbon steel with options for protective coatings or made from alloys for extreme conditions, the external ring ensures adaptability for higher temperature and challenging applications.
